Methods of setting up, caring for and later removing a temporary
rasta hairstyle
Abstract
A method of setting up, caring for and later removing a
temporary rasta hairstyle is disclosed. This method includes
applying a roughness-increasing substance to the hair to roughen
the hair, optionally, but preferably, applying an
adherence-increasing substance to the hair to increase adherence of
hairs to each other, and subsequently setting up the temporary
rasta hairstyle by intertwining hair strandwise. The cleaning of
the temporary rasta hairstyle occurs preferably using a concave
sponge, without disturbing the temporary rasta hairstyle. To again
remove the temporary rasta hairstyle a composition that increases
the combability is applied to the hair and the rasta strands are
opened and unwound or untwisted. Multi-component kits and
compositions for performing the method are also described.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to methods for setting up,
caring for and later removing a temporary rasta hairstyle, to
compositions and ingredients used in the methods and to multi-part
kits for performing the methods.
[0003] 2. Description of the Related Art
[0004] A permanent rasta hairstyle is a hair fashion comprising
tightly braided long braids usually comprising thin and extremely
strongly interlocked hair strands. These types of hairstyles are
also called dreadlocks. Both names are used synonymously in the
following description. Ethnic hair (e.g. African or Afro-American
hair, so-called kinky hair) is ideal for setting up dreadlocks or
rasta hairstyles because of its naturally curliness and its nature.
However rasta hairstyles can be set up with other, among others,
smooth, hair, such as middle European or Asiatic hair, with
suitable techniques. It is necessary however to produce a hair
structure that tends to facilitate strongly interlocking the hair
strands prior to forming the locks. This usually occurs by a
combination of chemical and mechanical treatments of the hair.
First it is necessary that the hair is made dull. Hair flake or
scale should not be present on the hair shaft, but should be
removed as much as possible. The chemical treatment can occur with
a hair reducing agent (e.g. thio compounds, such as thioglycolic
acid), such as is used in a permanent wave treatment, but with the
difference that the effective concentration and/or action is
greatly increased. During this latter treatment the cuticle layer
is probably at least partially or entirely removed to increase the
required tendency of the hair strands to interlock. Another
chemical treatment is an alkaline treatment with strong alkali
compositions, e.g. corn soap or an alkaline shampoo without care
additives. Furthermore an intense mechanical treatment of the hair
is required to remove the flake or scale. This can occur by an
intense "toupier" of the hair as strong as possible for several
hours with a very fine comb, e.g. with a lice comb or similar comb,
usually with stable metal teeth. "Toupier" of the hair is also
called "back combing". These terms are used synonymously in the
following.
[0005] During back combing there is an intense irreversible
interlocking of the hair and the hair is irreparably damaged.
Another problem besides hair damage is that the rasta hair style is
permanent when set up with the conventional hair techniques and is
not removable. The interlocking of the hair is irreversible, i.e.
it cannot be reversed without more. Those who set up this hairstyle
once only remove it by cutting off the hair with a scissors. Some
fashion-conscious users would like to have a rasta hairstyle only
temporarily or only for a certain occasion, e.g. for a party on the
weekend, and would like to switch back to their original hairstyle
the next day without damaging their hair. Thus there is a strong
demand for a removable temporary rasta hairstyle that does not
entail damaging hair treatment steps.
[0006] An additional problem with the conventionally set up rasta
hairstyle is hygienic. There is thus a need for cleaning strongly
interlocked hair strands, which is currently difficult or not
possible. There is thus a danger that the interlocked hair strands
can come apart from within, can be damaged and even break off or
fall out. Thus for the user, who wants to have a rasta hairstyle
for a long time, a method is thus desirable, which permits the
opening or separation of the strands after a certain time. Thus the
desired rasta hairstyle can be set up anew after an intense hair
cleaning and/or hair care treatment.
SUMMARY OF THE INVENTION
[0007] It is an object of the present invention to provide a method
of setting up a temporary rasta hairstyle, which does not suffer
from the above-described disadvantages and which can be removed
later without damaging the hair.
[0008] It is a further object of the present invention to provide
compositions for effectively performing the method of setting up a
temporary rasta hairstyle according to the invention.
[0009] It is another object of the claimed invention to provide a
multi-part kit for the method of setting up a temporary rasta
hairstyle according to the invention.
[0010] It has now been found that these objects can be surprisingly
attained by a method according to the invention of setting up a
temporary rasta hairstyle and later removing it.
[0011] According to the invention this method includes the
following steps:
[0012] a) applying one or more roughening substances to the hair
that increases the roughness of the hair surface;
[0013] b) preferably but optionally applying one or more
adhesion-increasing substances to the hair to increase adherence of
hairs to each other; and
[0014] c) setting up temporary rasta strands by intertwining the
hair strand-wise, without essentially, i.e. irreversibly,
interlocking the hairs.
[0015] The intertwining of the hair strands can occur e.g. either
by gently back combing or by one or more of dividing, drawing apart
and twisting the divided hair strands, or by a combination of
twisting the strands around their long axis and gently back combing
the twisted strands. The cleaning of the temporary rasta hair style
can occur using a concave sponge, without destroying the hair
style. In order to remove the temporary rasta hairstyle a
composition increasing the wet combability of the hair is applied
to the hair. The rasta strands are opened and/or unwound,
preferably mechanically using an ordinary comb or brush.
[0016] It was surprisingly found that it is possible to produce an
authentic or at least nearly authentic rasta-look or rasta
appearance, like a "true" permanent rasta, without damaging the
hair and without the up to now strongly irreversibly interlocked
hairs considered as a prerequisite. Furthermore it was surprising
that the removal of the rasta hairstyle is possible simply without
problems. The hair makes an even better cared for and healthier
impression than prior to treatment after removal of the temporary
rasta hairstyle, especially regarding the feel, luster and
combability. This is immediately astonishing, since up to now a
rasta hair style is almost synonymous with strongly damaged and
uncared for hair. Now with the methods according to the invention
the opposite has been achieved. The care action is partially what
one would have expected from the action of the remover composition
C that is described in detail hereinbelow. This means that it is
based on a synergistic care action of the remover composition C in
combination with the pre-treatment composition A and/or B described
in more detail below.
[0017] The subject matter of the invention is thus a method of
setting up a rasta hairstyle, in which at least one roughening
substance for roughening the hair surface is applied to the hair
and subsequently a temporary rasta hairstyle is set up. The term
"temporary rasta hairstyle" means a hairstyle with the appearance
of a rasta look, which is again removable in contrast to a
permanent rasta hairstyle. In contrast to the permanent rasta
hairstyle the hair is not essentially or substantially interlocked,
but only intertwined, i.e. the hairs that are twisted together can
be mechanically separated from each other again. The roughening
substance that increases the roughness of the hair surface is a
substance, which adheres to the hair surface and causes clean hair
to feel rough or dull in contrast to hair that has not been
treated. This substance can be applied to the hair by means of
composition A, which is described in more detail hereinbelow.
[0018] The stability of the temporary rasta hairstyle is clearly
increased when an adhesion-increasing substance that increases the
adherence of the hairs with each other is applied to hair and/or to
the hair tips that has or have been pre-treated with the roughening
substance increasing the surface roughness. The application of the
adhesion-increasing substance increasing the adhesion of the hairs
with each other can occur by means of the composition B that is
described in more detail hereinbelow. The adhesion-increasing
substance can be applied either prior to or after setting up the
rasta hairstyle as necessary.
[0019] Setting Up of the Temporary Rasta Hairstyle
[0020] To set up the temporary rasta hair style hairs that are
predetermined according to the invention are arranged or put in one
or more temporary dreadlocks. This can occurs by several methods.
One of the three following methods is recommended for doing this.
The recommended methods are to be understood as exemplary
embodiments. In all of these techniques the setting up of the
dreadlocks begins on the neck. Moreover one section (for example of
about three cm thick) is divided from side to side transversely to
the head. The base surface of the individual dreadlocks (individual
strands) depends on the desired thickeness/density, amounting
usually to 6 to 9 cm.sup.2 and can be square, rectangular,
trapezoidal or triangular. One works in the direction of the
forehead in these methods or techniques. The dreadlocks are laid
over each other in the manner of shingles. In order to improve the
planed hairstyle, the dreadlocks are preferably held directly in
the desired direction during setting up of the hairstyle.
[0021] An Especially Preferred Method
[0022] The separated individual strand is uniformly gently
back-combed (intertwined, not interlocked) with a back comb from
the hair roots to the hair tips. During the back combing the
individual strand is twisted over its long axis, whereby a special
round and "true" appearing dreadlock is produced.
[0023] An Additional Preferred Method
[0024] The separated or divided individual strand is strongly
twisted with the fingers over its long axis. After 2 to 3 twists
the hair strand is arbitrarily divided at the tips. Both hair
strands arising by the division are now spread from each other,
whereby the two to three prior twists move toward the hair roots
and intertwine (similar to back bombing). The twist, division and
spreading of the hair strand is performed until the entire length
of the individual strand is intertwined.
[0025] Additional Possible Method
[0026] The separated or divided individual strand is strongly
twisted with the fingers over its long axis, until the entire
strand is effectively "knurled". The hair tips of the hair strand
are held fixed and the spreading on the long axis is somewhat
reduced. Now the already twisted strand is gently back combed with
a suitable back comb, without interlocking the hairs. The back
combing occurs over the entire axial length of the individual
strand. After that the twisted and back combed strand is rolled
between the thumb and index finger once more in order to augment
the intertwining effect.
[0027] Composition A
[0028] The application of the roughening substance increasing the
roughness of the hair surface can occur by means of a first
composition A. Suitable substances are e.g. those substances, which
are solid at room temperature (25.degree. C.) and are present in
the form of particles. Silica, silicates, aluminates, clays, micas,
salts, especially inorganic metal salts, metal oxides, e.g.
titanium dioxide, minerals and polymers are somewhat suitable.
Polymers, which impart a rough dull feel to the hair, are suitable.
The suitability of a polymer is established by half-side tests of
polymerically treated hair in contrast to untreated hair.
[0029] Suitable roughening polymers are, for example, copolymers of
alkylacrylamides, especially C.sub.1-C.sub.8-alkyl groups, and at
least one monomer selected from the group consisting of acrylic
acids, methacrylic acids and their simple esters, especially the
C.sub.1-C.sub.4-alkyl esters (INCI: acrylates/octylacrylamide
copolymer, acrylates/t-butylacrylamide copolymer, e.g.
Amphomer.RTM. HC and/or Ultradhold.RTM. 8); copolymers of vinyl
methyl ether and alkyl hemiesters of maleic acid, especially
C.sub.1-C.sub.5-alkyl hemiesters (INCI: butyl ester of PVM/MA
copolymer, e.g. Gantrez.RTM. ES 425; copolymers of vinyl acetate
and crotonic acid (INCI: VA/crotonates copolymer, e.g. Luviset.RTM.
CA 66).
[0030] The roughening substance can be present in the form of solid
particles in the composition A and preferably the solid particles
are dispersed in the composition to form a stabile dispersion.
Alternatively they can be present in dissolved form in a suitable
cosmetically acceptable solvent. They are then separated from the
solution after applying the solution to the hair and evaporating
the solvent. A stabile dispersion can be attained, when the
composition A is provided with a flow limit, which is sufficiently
large, in order to prevent the settling of the solid particles. A
sufficient flow limit can be adjusted to a suitable value by using
a suitable gel former.
[0031] Silica (silica gel, silicon dioxide) and metal salts,
especially inorganic metal salts, are especially preferred as the
roughening substance applied to the hair. Silica is most preferred.
The metal salts include, e.g., alkali or alkaline earth metal
halides, such as sodium chloride and potassium chloride; alkali or
alkaline earth sulfates, such as sodium sulfate or magnesium
sulfate. In the event that a soluble metal salt is used composition
A is preferably an aqueous solution of this salt and is preferably
in combination with a spraying device, e.g. a mechanically operated
spray pump. In case insoluble particles are used, which are not
soluble in water, alcohol and/or an alcohol/water mixture, such as
silicon dioxide or a metal oxide, composition A is preferably a gel
having a flow limit or yield point and contains at least one gel
former that establishes the flow limit. Alternatively composition A
is a foamable composition containing at least one foam-forming
surfactant and/or foam-forming polymer. The foaming can occur by an
aerosol propellant or by means of a mechanically operated apparatus
for making foam.
[0032] In the case of the embodiments of composition A that are
gel, thickening polymers are included, which impart a plastic or
pseudo-plastic behavior to the compositions. The rheological flow
properties of the gel according to the invention are characterized
by the existence of a flow limit. The flow limit preferably amounts
to at least 3 Pascal, measured with a Haake Rotation Viscometer RV
12, measurement system PKV-0.5 at 30.degree. C. and at a linearly
increasing shear rate of 0 to 100 s.sup.-1. After exceeding the
flow limit the gel preferably has a viscosity of 1,000 to 100,000
mPa.s, especially from 5,000 to 50,000 mPa.s at 25.degree. C.,
measured with a Haake Rotation Viscometer Type VT 501 at a shear
rate of 12.9 per second. The flow point or flow limit is selected
according to weight and surface area of the particles so that it is
at least as large as the pressure exerted by the particles. The
settling of the particles is thereby prevented. The thickeners are
preferably contained in an amount of from 0.05 to 10, especially
preferably from 0.1 to 4, percent by weight, in composition A. The
optimum concentration is dependent on the type of thickener and the
weight of the particles. Suitable thickeners are cross-linked or
not cross-linked polyacrylic acids or polymethacrylic acids. These
thickeners, which can be contained in the compositions according to
the invention, include homopolymers of acrylic acid with a
molecular weight of 2,000,00 to 6,000,000 g/mol, which are marketed
e.g. by Goodrich, USA under the trademark Carbopol.RTM.. Additional
thickeners are e.g. the acrylic acid polymers, acrylic
acid/acrylamide copolymers or Sclerotium Gum, marketed under the
trademark Modarez.RTM. V 600 PX of Protex, France or under the
trademark Carbopol.RTM. ETD 2001 by Goodrich, USA. Copolymers of
acrylic acid or methacrylic acid, such as those marketed under the
trademark Carbopol.RTM. 1342 or Pemulen.RTM. TR1 of Goodrich, USA,
are suitable. Guar gum, xanthan gum, bentonite and hectorite are
additional suitable thickeners.
[0033] In an advantageous embodiment of the composition thickeners
are included in the composition besides those that impart a
sufficient flow limit or flow point in the viscosity range typical
for gels in addition to those thickeners that impart a sufficient
flow limit or flow point to the composition. These latter
thickeners include especially cellulose and cellulose derivatives,
such as carboxymethyl cellulose, cellulose ether and hydroxyalkyl
cellulose compounds. The thickeners contain acid groups, which are
at least partially neutralized with cosmetically compatible bases.
Suitable organic or inorganic bases that are appropriate for
cosmetic applications can be used as the neutralizing agents. For
example, the bases can include amino alcohols, such as
aminomethylpropanol (AMP), triethanolamine or monoethanolamine and
ammonia, NaOH and others.
[0034] Composition A also can be in the form of an aerosol or
non-aerosol sprayable or foamable product. The aerosol products
include a pressure-tight aerosol container with a spray or foam
head, which contains the foamable or sprayable composition. The
pressure-tight aerosol container of the aerosol spray product
according to the invention can be made from any material known for
aerosol spray or foam products. Metals, such as aluminum or tin,
are especially suitable materials. Preferably the aerosol
propellants are employed in an amount of from 1 to 20, especially
preferably from 2 to 10, percent by weight. For example, lower
alkanes, such as n-butane, i-butane, propane, butane, or also their
mixtures and dimethyl ether or fluorohydrocarbons, such as F 152a
(1,1-difluoroethane) or F 134 (tetrafluoroethane) are suitable as
the aerosol propellants. In addition, propellants present in
compressed gaseous form, such as N.sub.2, N.sub.2O and CO.sub.2,
and their mixtures are suitable as the propellants.
[0035] Preferably the composition comprises an aqueous or an
aqueous-alcoholic medium with preferably at least 10 percent by
weight water. The solvent system is preferably present in the
composition in an amount of 50 to 98, especially preferably from 75
to 95, percent by weight. The alcohols included in the solvent
system especially include lower alcohols having one to four carbon
atoms that are suitable for cosmetic purposes, such as ethanol and
isopropanol. Organic solvents or mixtures of solvents with a
boiling point under 400.degree. C. are suitable as co-solvents in
amounts of from 0.1 to 15, especially from 1 to 10, percent by
weight. Branched or unbranched hydrocarbons, such as pentane,
hexane, isopentane and cyclic hydrocarbons, such as cyclopentanes
and cyclohexane, are suitable as additional co-solvents. Glycerol,
ethylene glycol and propylene glycol are additional especially
suitable water-soluble solvents.
[0036] In the case of non-aerosol sprays and non-aerosol foams, the
compositions are present in combination with a mechanically
operated apparatus for spraying or forming.
[0037] The foamable products usually contain at least one
foam-producing substance, e.g. a foam-forming surfactant and/or a
foam-forming polymer. The surfactant can have nonionic, anionic or
amphoteric character. Nonionic foam-forming surfactants are
preferred. The surfactants can be used individually or in a
mixture. The amount of the surfactants can be varied and is
selected so that a sufficient amount of foam is formed for working
into the hair, when the composition is delivered from the aerosol
container or the product dispenser. The surfactant amount is
preferably typically from 0.01 to 5, especially preferably from 0.1
to 2, percent by weight. Suitable nonionic surfactants are, for
example, the C.sub.8- to C.sub.18-fatty alcohols, which can be
ethoxylated with from 8 to 45 mol ethylene oxide, e.g. lauryl
alcohol, tetradecyl alcohol, cetyl alcohol, oleyl alcohol or
stearyl alcohol, ethoxylated with up to 40 mol ethylene oxide per
mol fatty acid, alone or in a mixture; hydrogenated castor oil
ethoxylated with 8 to 45 mol ethylene oxide; C.sub.8- to
C.sub.18-fatty acid alkanolamides; fatty alcohols of ethoxylated
lanolin orethoxylated lanolin; polyglyceryl ethers of saturated or
unsaturated fatty alcohols and alkyl phenols with 8 to 30 carbon
atoms in alkyl groups and with 1 to 10 glyceryl units per molecule;
polyethylene/polypropylene block copolymers and ethoxylated
sorbitan fatty acid ester. Derivatives of natural surfactants, e.g.
alkylpolyglycosides, are especially preferred as the nonionic
surfactants. For example, alkyl sulfates, alkyl ether sulfates,
alkyl sulfonates, alkoyl sarcosinates, akly isethionate or
dialkylsulfosuccinates, which contain from 8 to 18 carbon atoms,
are suitable anionic surfactants. Betaines are especially suitable
as amphoteric surfactants. For example, the betaines include

cocodimethylcarboxymethylbetaine,
lauryldimethylcarboxymethylbetaine,
lauryldimethyl-alpha-carboxyethylbetaine,

acid alkylamidobetaines, such as coconut fatty acid
amidopropylbetaine, and N-coconut fatty acid
amidoethyl-N-[2-(carboxymethoxy)ethyl]glycerol (CTFA:

[0038] Composition B
[0039] The application of the adhesion-increasing substance causing
the hairs to adhere to each other can occur by means of a second
composition B. Suitable substances are, e.g., waxes, waxy materials
and/or adhesive polymers. Waxes and waxy materials are especially
those substances with the properties according to the definition of
waxes in Ullmanns' Encyclopedia of Industrial Chemistry, 4.sup.th
Edition, Volume 24, page 3. According to this Encyclopedia the
waxes are kneadable at 20.degree. C., solid to brittle and hard,
fine to gross crystalline, at least translucent to opaque, however
not glassy, melting over 40.degree. C. without decomposition,
comparatively low viscosity a little over its melting point,
strongly temperature dependent in its consistency and solubility
and polishable under a gentle pressure. In the following the terms
"wax substance" and "waxy or wax-like substance" are synonymous in
the following. Adhesive polymers, which are suitable, include those
polymers, which impart an adhesive feel to the hair, as established
by half-side tests of polymerically treated hair in comparison to
untreated hair.
[0040] Suitable hydrophobic waxes include animal, plant, mineral
and synthetic waxes, microcrystalline waxes, solid paraffins,
petrolatum, Vaseline.RTM., ozokerite, montan wax, Fischer-Tropsch
wax, polyolefin waxes, for example polybutene, beeswax, wool wax
and its derivatives, e.g. wool wax alcohols, candelilla wax,
carnauba wax, Japan wax, hardened fats, fatty acid esters and fatty
acid glycerides with a solidification point of over 40.degree. C.,
polyethylene waxes and silicone waxes. The waxes have a
solidification point of over 40.degree. C., preferably over
55.degree. C. The needle penetration number (0.1 mm, 100 g, 5 s,
25.degree. C., according to DIN 51 579) is preferably in a range of
from 2 to 70, especially from 3 to 40, especially preferably less
than 20. Carnauba wax, ceresin wax and their mixtures are
especially preferred. The waxes and waxy materials in composition B
are preferably contained in an amount of from 4 to 50, especially
preferably from 8 to 30, and particularly preferably from 10 to 25,
percent by weight.
[0041] In an especially preferred embodiment composition B is an
aqueous emulsion of a hydrophobic wax and contains at least one
emulsifier and water in addition to the wax. The term "emulsion"
includes wax dispersions in water, but also suspensions of solid
wax particles in water. The emulsifiers are, preferably, contained
in an amount of 0.5 to 50, especially from 3 to 40, and
particularly from 20 to 35, percent by weight.
[0042] Preferably the emulsifiers are nonionic surfactants. The
following emulsifiers are especially suitable: [0043] addition
products of 2 to 30 mol ethylene oxide and/or 1 to 5 mol propylene
oxide to C.sub.8- to C.sub.22-fatty alcohols, to C.sub.12- to
C.sub.22-fatty acids or to alkanol phenols with C.sub.8- to
C.sub.15-alkyl groups; [0044] C.sub.12- to C.sub.22-fatty acid
monoesters or diesters of addition products of from 1 to 30 mol
ethylene oxide to glycerol; [0045] addition products of 5 to 60 mol
ethylene oxide to castor oil or to hardened (hydrogenated) castor
oil; and [0046] mon-, di- and triesters of phosphoric acid with
addition products of 2 to 30 mol ethylene oxide to C.sub.8- to
C.sub.22-fatty alcohols.
[0047] In an especially preferred embodiment the total amount of
the emulsifiers present is larger than the total amount of the
waxes. That means that the weight ratio of the emulsifier to wax is
larger than 1:1, preferably up to 5:1, especially preferably from
1.5:1 to 3:1. These embodiments are characterized by a combination
of individual active ingredients. Directly after the application to
the hair the adhesion force of the hairs is very high, which very
much simplifies the setting up of a rasta hairstyle. After drying
the adherence is greatly reduced, which leads to an improved
pleasant feel. A reduced, not unpleasant, residual adhesion remains
and causes the finished rasta strands to adhere loosely to each
other, which provides additional fresh hair styling possibilities.
The preferably advantageous automatically decreasing adhesion force
is especially strongly expressed in combination with silica as the
roughening substance that increases the roughness of the hair. An
additional especially advantageous effect is the sufficiently good
residue-less removal of the hydrophobic wax, especially using the
composition C described further below for removing the rasta
hairstyle. Composition B is present ideally in liquid, i.e. liquid
or viscous form. It is preferably dispensed in liquid form by means
of a pumping device, sprayed as a spray by means of a spraying
device or as foam with an apparatus for producing foam. For
additional ingredients for the aerosol and non-aerosol embodiments
reference is made to the similar ingredients described above as
suitable for composition A.
[0048] As waxes however hydrophilic waxes can be used, especially
high molecular weight polyethylene glycols (PEG). The polyethylene
glycols are preferably waxy solids at room temperature (20 to
25.degree. C.) or at least soft waxy-like compositions with a
solidification temperature at about 30.degree. C., preferably at
about 40.degree. C. The molecular weight amounts to preferably from
850 to about 5000 g/mol, especially preferably from 1200 to 3500
g/mol. Polyethylene glycols have the general formula
H(OCH.sub.2CH.sub.2).sub.nOH. Suitable high molecular weight
polyethylene glycols are, e.g., those with n=19 to 113, preferably
with n=30 to 79. Suitable polyethylene glycols have the INCI-name
PEG-20 (n=20), PEG-32 (n=32), PEG-60 (n=60), PEG-75 (n=75), PEG-90
(n=90) and PEG-100 (n=100). Commercial products usually have a
molecular weight distribution. Suitable commercial products are,
e.g., polyglycol 1000, polyglycol 1350, polyglycol 1500, polyglycol
3000 or polyglycol 4000 of Clariant. The numerical values designate
approximately the average molecular weight.
[0049] Rasta-Cleaning
[0050] To care for the temporary rasta hairstyle as careful as
possible a cleaning without application of greatly stressing the
rasta strands is recommended. Careful cleaning comprises moistening
the hair and then applying a hair cleaning composition, which
contains at least wash-active surfactant, to the hair or a sponge.
Then the composition is cautiously distributed on the hair, e.g. by
dabbing with the sponge. Subsequently the cleaning composition is
removed from the hair, which occurs by rinsing with water or by
dabbing with the sponge after rinsing it many times in the
meantime. The sponge preferably has a concave shape. The concave
shape approximately corresponds to the shape of the head. The
application, distribution and/or removal of the cleaning
composition on the hair occur with the concave inner side of the
sponge.
[0051] Rasta-Removal
[0052] The removal of the temporary rasta-hairstyle set up
according to the invention can occur by moistening the hair,
applying a remover composition C to the hair and distributing it on
the hair. The rasta strands are then opened or unwound. Finally the
composition C can be rinsed from the hair.
[0053] Composition C
[0054] The composition C contains at least one substance that
enhances the wet or moist combability. This combability enhancing
substance is preferably contained in the composition C in an amount
of from 0.01 to 10, especially preferably from 0.05 to 5, percent
by weight. For example, cationic polymers, cationic surfactants,
amine oxides, cationic silicone compounds, oil ingredients, fatty
alcohol and glycerol fatty acid monoesters, are suitable. Suitable
cationic surfactants include those, which contain a quaternary
ammonium group and at least one organic residue with at least six
carbon atoms. Suitable carionic surfactants can be of the general
formula: N.sup.(+)R.sup.1R.sup.2R.sup.3R.sup.4X.sup.(-) wherein
R.sup.1 to R.sup.4 each represent, independently of each other, an
aliphatic group, an aromatic group, an alkyoxy group, a
polyoxyalkylene group, an alkylamido group, a hydroxyalkyl group,
an aryl group or alkylaryl group, each of the foregoing groups
having from 1 to 22 carbon atoms, wherein at least one of the
groups has at least six carbon atoms and X.sup.- represents an
anion. The anion can be a halogen anion, acetate, phosphate,
nitrate or alkyl sulfate, preferably a chloride anion. The
aliphatic group can contain cross-linking or other groups, such as
amino groups, in addition to the carbon and hydrogen atoms. The
groups can be linear, branched or cyclic. For example, the
following are suitable cationic surfactants: the chlorides or
bromides of alkyldimethylbenzyl ammonium salts, of alkyltrimethyl
ammonium salts, for example cetyltrimetyl ammonium chloride or
bromide, tetradecyltrimetyl ammonium chloride or bromide,
alkyldimethylhydroxyethyl ammonium chloride or bromide, the

at least six carbons in the alkyl groups. Cetyltrimethyl ammonium
chloride is particularly preferred as the cationic surfactant.
[0055] Cationic polymers in the sense or the present invention are
those polymers, which contain at least one cationic or cationizable
group that becomes a cationic group when protonated. Cationic
groups, for example, include quaternary amine groups. Cationizable
groups, for example, include primary, secondary or tertiary amine
groups. The cationic polymers can be homopolymers or copolymers, in
which the cationic or cationizable groups are either in the polymer
chain or preferably present as substituents on one or more of the
monomers.
[0056] Suitable monomers of the cationic polymer, which have
cationizable groups, are unsaturated radically polymerizable
compounds, which have at least one neutralized or not neutralized

halides or methacrylamidoalkyltrialkyl ammonium halides,
trialkylmethacryloxyalkyl ammonium halides, trialkylacryloxyalkyl
ammonium halides, dialkyldiallyl ammonium halides or quaternary
vinyl ammonium monomers with groups containing cyclic, cationic
nitrogen, such as pyridinium, imidazolium or quaternary
pyrrolidone, e.g. alkylvinylimidazolium, alkylvinylpyridinium, or
alkylvinylpyrrolidone salts, are suitable. The alkyl groups of
these preferred monomers preferably include lower alkyl groups,
such as C.sub.1- to C.sub.7-alkyl groups, especially preferably
C.sub.1- to C.sub.3-alkyl groups. Acrylamidopropyltrimethyl
ammonium chloride and methacrylamidopropyltrimethyl ammonium
chloride are particularly preferred.
[0058] The cationic polymer can be polymerized, as needed, with

[0060] Chitosan or a chitosan derivative, which is neutralized with
a cosmetically compatible acid, is also suitable as a cationic

Additional chitosan and chitosan derivatives are also suitable. The

which deposits a polymer film on the hair, when applied to the hair
in a 0.01- to 5-percent aqueous, alcoholic or aqueous-alcoholic
solution.
[0087] Suitable synthetic, nonionic film-forming hair-fixing
polymers are homo- or copolymers, which are built up from at least
one of the following monomers: vinyl pyrrolidone, vinyl
caprolcactam, vinyl esters, such as vinyl acetate, vinyl alcohol,
acrylamide, methacrylamide, alkyl- and dialkylacrylamides, alkyl-
and dialkylmethacrylamides, alkylacrylates, alkylmethacrylates,
propylene glycol or ethylene glycol. The alkyl groups in these
monomers preferably have from one to seven carbon atoms, especially
preferably from one to three carbon atoms.
[0088] Suitable nonionic film-forming hair fixing polymers are, for
example, homopolymers of vinylcaprolactam, of vinyl pyrrolidone or
of N-vinylformamide. Additional suitable synthetic film-forming,
nonionic, hair-fixing polymers are, for example, copolymerizates of
vinyl pyrrolidone and vinyl acetate, terpolymers of vinyl
pyrrolidone, vinyl acetate and vinyl propionate, polyacrylamides,
polyvinyl alcohols and polyethyleneglycol/polypropyleneglycol
copolymers. Polyvinyl pyrrolidones and copolymers of vinyl
pyrrolidone and nonionic comonomers, especially polyvinyl
pyrrolidoine/vinyl acetate copolymers, are particularly preferred.
Suitable natural film-forming polymers are, e.g. cellulose
derivatives, especially hydroxyalkyl cellulose compounds, such as
hydroxypropyl cellulose.
[0089] The compositions of the invention can also include the
following conventional cosmetic additive ingredients suitable for
this type of hair treatment composition: e.g. perfume oils, in an
amount of from 0.01 to 0.5 percent by weight; propellants, e.g.
ethylene glycol distearate, in an amount of about 0.2 to 5.0
percent by weight; preservatives, e.g. parabene in an amount of
from 0.01 to 1.0 percent by weight; buffer substances, such as
sodium citrate or sodium phosphate, in an amount of from 0.1 to 1.0
percent by weight; care substances, e.g. plant and vegetable
extracts, proteins and silk hydrolyzates, lanolin derivatives, in
an amount of from 0.1 to 5 percent by weight; physiologically
compatible silicone derivatives, e.g. volatile or non-volatile
silicone oils or high molecular weight siloxane polymers, in an
amount of 0.05 to 20 percent by weight; light-protective agents;
antioxidants, radical-trapping agents; anti-flaking agents, in an
amount of about 0.01 to 2 percent by weight, direct dye compounds,
luster-imparting substances, vitamins, softeners and de-fatting
agents.
[0090] The following example illustrates the invention in more
detail, but these details should not be considered as limiting the
claims appended hereinbelow.
EXAMPLE
Rasta Hairstyle Setup
[0091] The hair is washed with a conventional shampoo, preferably a
non-conditioning neutral shampoo. About 6 to 15 g (according to
hair length) of the following composition A is uniformly
distributed on the hair.
[0092] Composition A: TABLE-US-00001 1 g Fluisil .RTM. 300 (Silica)
0.8 g Rewoteric .RTM. AM CAS (Cocamidopropyl hydroxysultaine, 50
percept in water) 0.4 g Oramix .RTM. NS 10 (Decyl glucoside, 55
percent in water) to 100 g water
Filled with propane/butane in a ratio of 96:4.
[0093] After drying the hair a crest is pulled and the hairs on the
nape of the neck are divided into equal width portions. These
portions are subdivided into uniform sized squares or triangles.
The hair strands are back combed gently from the roots to the tips
with a gentle twisting motion. The strands are held in the desired
fall direction of the dreadlocks during working. After back combing
all the strands of the entire head are sprayed individually with
the following composition B and twisted or rotated into the desired
shape.
[0094] Composition B: TABLE-US-00002 17.8 g PEG-60 hydrogenated
castor oil 11.9 g Carnauba wax 8.9 g PEG-40 hydrogenated castor oil
to 100 g water
This composition is provided in a container with a pump spray
apparatus. Washing of the Rasta Hairstyle The hairstyle is
sufficiently moistened with a shower or gentle water jet under the
shower. A mild shampoo is applied to the concave inner side of a
concave moistened wash sponge. By dabbing the hair-do (no circular
motions) foam is produced from the shampoo. However it is rinsed
away gently. After the washing the dreadlocks are again twisted or
rotated using composition B. Removal of the Rasta Hairstyle
[0095] After washing a cationic hair care composition of the
following composition C is worked into the moist hair.
[0096] Composition C: TABLE-US-00003 6.0 g Cetearyl alcohol 1.35 g
Vaseline .RTM. 1.2 g Paraffinum Perliquidum 1.0 g Cetyltrimethyl
ammonium chloride 0.3 g Lanolin alcohol 0.15 g Lanolin 0.5 g
Silicone oil 0.5 g Citric acid to 100 g water
[0097] After an acting time of about five minutes, the dreadlocks
are released or removed. The hair care composition then remains on
the hair. The dreadlocks are cautiously combed out from the hair
tips to the hair roots with a hand comb. After removing the
dreadlocks the hair care composition is rinsed out of the hair.
Subsequently a desired new hairstyle is set up.
[0098] The disclosure in German Patent Application 102 34 804.9 of
Jul. 31, 2002 is incorporated here by reference. This German Patent
Application describes the invention described hereinabove and
claimed in the claims appended hereinbelow and provides the basis
for a claim of priority for the instant invention under 35 U.S.C.
119.
[0099] While the invention has been illustrated and described as
embodied in a method for setting up, caring for and removing a
temporary rasta hairstyle, to compositions and ingredients used in
the method and to a multi-part kit for performing the method, it is
not intended to be limited to the details shown, since various
modifications and changes may be made without departing in any way
from the spirit of the present invention.
[0100] Without further analysis, the foregoing will so fully reveal
the gist of the present invention that others can, by applying
current knowledge, readily adapt it for various applications
without omitting features that, from the standpoint of prior art,
fairly constitute essential characteristics of the generic or
specific aspects of this invention.
