Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a hair extension system and
method for attaching such a system to a wearer's head.
[0002] In my co-pending application Ser. No. 09/836,918 filed Apr.
18, 2001, a hair integration system for extending over the entire
head is described. However, in some cases, it is desired to add a
lesser amount of hair to the head, and smaller hair extensions are
often used for this purpose.
[0003] Hair extensions of natural or artificial hair are often used
in the hairdressing field in order to provide the appearance of
longer or thicker hair. Such extensions are used for cosmetic
reasons, in order to enhance the appearance of natural hair or
change its look, or in order to supplement thinning hair. Some hair
extension methods involve adhering bunches of extension hair to a
person's natural hair, which is an expensive and time consuming
process. A method of this type is described, for example, in U.S.
Pat. No. 5,107,867 of Barrington. In U.S. Pat. No. 5,894,846 of
Gang, a method for lengthening and thickening hair is described. In
this method, a knotted strand of the persons own hair is disposed
in one end of a tube. An extension piece of hair extends from the
other end of the tube. This process is repeated over the person's
head. Again, the process is extremely time consuming, typically
taking several hours to complete.
[0004] One problem with attaching hair extensions by adhering to
the person's own hair is that the hair extensions will grow out as
the natural hair grows. Also, significant shedding of supplemental
hair tends to occur as a result of brushing, washing, or other
normal hair grooming activities. This is frustrating for the client
who has invested a significant amount of time and money in the hair
extension process.
SUMMARY OF THE INVENTION
[0005] It is an object of the present invention to provide a new
and improved hair extension system and method.
[0006] According to one aspect of the present invention, a hair
extension system is provided, which comprises a skin-simulating
layer having an inner face for attachment to a wearer's scalp and
an outer face, the skin-simulating layer having an opening for
pulling a portion of a wearer's existing hair through the opening,
and a plurality of hair strands secured to the skin simulating
layer around the opening to extend from the outer face of the layer
in order to imitate naturally growing hair.
[0007] In an exemplary embodiment of the invention, the
skin-simulating layer is of a stretchable material having a
curvature for substantially matching the curvature of the wearer's
scalp, so that it can adhere in close, face-to-face engagement with
the scalp. The layer may comprise two arcuate strips or bands which
are connected together at their outer ends, with the opening being
generally crescent-shaped. The layer may be formed integrally in
one piece from a single sheet of material having a curvature and
with a suitable crescent-shaped cut-out to form the hair
pull-through opening.
[0008] The skin-simulating material may be a product of the type
generally known as artificial or man-made skin, which is normally a
polyurethane material of a skin-tone color, and is stretchable to
be more readily conformed and adhered to a wearer's scalp. It may
be adhered to the scalp by a suitable grafting agent or
adhesive.
[0009] According to another aspect of the present invention, a hair
extension method is provided, which comprises the steps of:
[0010] parting a wearer's hair to form a central bunch of hair with
first and second part lines following a generally crescent-shaped
path;
[0011] tying the bunch of hair together in a pony tail;
[0012] applying a layer of adhesive to an inner face of a
skin-simulating layer of a hair extension device having hair
attached around the outer face of the skin-simulating layer, the
skin-simulating layer having upper and lower generally arcuate
strips joined together at their outer ends and defining a generally
crescent-shaped opening between the strips;
[0013] pulling the pony tail through the opening in the hair
extension device with the inner face facing towards the wearer's
scalp;
[0014] pressing the inner face of the skin-simulating layer along
the part lines of the wearer's scalp around the opening to adhere
the hair extension device to the scalp; and
[0015] releasing the wearer's hair from the pony tail and
integrating the hair extending through the opening with the hair
attached to the layer surrounding the opening.
[0016] This arrangement allows a hair extension device to be
adhered directly to the wearer's scalp, so that it does not grow
out as the hair grows. The arrangement of a hair extension device
with an opening through which the wearer's own hair extends allows
the natural hair to be integrated with the hair on the extension
device for a more natural look.
BRIEF DESCRIPTION OF THE DRAWINGS
[0017] The present invention will be better understood from the
following detailed description of an exemplary embodiment of the
invention, taken in conjunction with the accompanying drawings in
which like reference numerals refer to like parts and in which:
[0018] FIG. 1 is a perspective view, from the inside of the hair
extension device according to an exemplary embodiment of the
invention.
[0019] FIG. 2 is a side view of a head showing the extension fitted
under and incorporated into the hair; and
[0020] FIG. 3 is a side view with the hair cut away to show the
attachment of the hair extension.
DETAILED DESCRIPTION OF THE DRAWINGS
[0021] The drawings illustrate a hair extension system and method
according to an exemplary embodiment of the present invention. A
hair extension device 10 comprises a layer of skin-simulating
material having a central, generally crescent-shaped opening 12
defining an upper strip 14 and a lower strip 15 of the material
which are joined together at their outer ends or corners 16. The
skin layer has an outer face 17 from which hair strands 18 project
so as to substantially cover the entire outer surface of the
device. The strands 18 extend outwardly from the device so as to
imitate naturally growing hair. The hair strands may be of any
desired color or blend of colors, depending on the wearer's own
natural hair color. Normally, at least two to three separate hair
colors are blended to produce the desired natural effect.
[0022] The upper band or strip 14 may be narrower than the lower
strip 15 so that more hair is added at the back of the head. In an
exemplary embodiment, the upper strip had a width of around 3/4",
while the lower strip width was 1". This provides medium hair
density at the crown and temples of the head, and medium heavy hair
density at the nape, when the extension is installed. The hair used
in the extension system may be natural or artificial, and in the
exemplary embodiment a type of human hair known in the hairdressing
field as "Remi" hair was used.
[0023] The skin layer is suitably formed in one piece from a
stretchable, skin simulating polyurethane material which is
skin-toned. The material is molded to form a relatively thin layer
which is curved to follow the natural curvature of the scalp,
before cutting out the central, generally crescent-shaped opening
12. Thus, rather than using a flat sheet of material and cutting it
out to the illustrated shape, a curved sheet is used to form the
device 10. This will more naturally follow the contours of a
wearer's head when attached to the scalp, so there is a better,
closer bond to the scalp and less risk of the device becoming
loose. The hair strands have ends which are actually embedded in
the polyurethane material of the skin layer while it is curing,
providing a much stronger bond and reducing the risk of premature
shedding. The ends are formed into a V-shape before embedding into
the polyurethane while it is still molten, and the material is then
allowed to cure while the hair ends are in place. This produces a
natural appearance and flow to the hair. The hair can be parted or
brushed to one side, since the V-root technique will allow each
hair to pivot through 360.degree..
[0024] The inner face 19 of the skin-simulating layer is designed
to be bonded or adhered to the wearer's scalp 20 with a layer of
adhesive or grafting solution 21, as best indicated in FIG. 3.
Prior to application to the scalp, the wearer's hair is parted
along two spaced lines corresponding generally to the stretched
shape of the opening 12, and the hair is separated along the part
lines. The portion or bunch 22 of hair contained within the part
lines is secured together in a pony tail by a suitable band or pony
tail holder, and the other hair is clipped out of the way. Grafting
solution is applied to the scalp along the part lines, and to the
entire inner face of the skin-simulating layer. The bunch 22 of
hair is then pulled through the opening 12, and the two strips 14,
15 of the extension device are pressed down along the part lines to
bond to the wearer's scalp. Once the device is bonded or grafted to
the wearer's scalp 21, the pony tail holder is removed and the
wearer's hair protruding through the opening 12 is integrated with
the hair 18 extending from the extension device.
[0025] The extension device may be trimmed readily around its
periphery if desired, for example if a customer has a smaller head
or if they want less added weight on their head. For example, the
hairdresser may cut across the outer ends to shorten them, or even
separate the upper band from the lower band. In this case, each
band will be adhered separately to the scalp. Alternatively, or
additionally, the outer edge of each band may be trimmed. The
artificial skin is relatively thin and easily cut to any desired
size.
[0026] The curvature and peripheral shape of the skin-simulating
layer of the hair extension device is such that it can be bonded
closely in face-to-face engagement with the scalp. The extension
hair follows the natural growing direction of hair from the
wearer's scalp and can be more readily integrated with the wearer's
remaining hair, as can be seen in FIG. 3. Since the bands or strips
forming the skin layer follow the natural curvature of the head,
they can be adhered more closely to the scalp, with less risk of
separation. The hair extension device can be worn for six to eight
weeks without requiring re-attachment, which is significantly
longer than for existing hair extension devices and techniques.
[0027] This hair extension system is particularly suitable for
individuals with fine or relatively thin hair, unlike previous
extensions which typically worked best with relatively thick, dense
hair in order to camouflage the attachment. Since the hair
extension device of this invention has a base which bonds in a
thin, flexible layer directly to the wearer's scalp, it will not be
visible to the eye, even for user's with relatively thin or fine
hair, and will actually remain securely attached to the scalp for a
longer period of time when the wearer has thin hair, since there
will be less grow out. The stretchable artificial skin contours
easily to the curvature of the wearer's head, ensuring a more or
less perfect fit. Since it has no seams or bumps, it is very
comfortable to wear and can be slept in without problem. It is
undetectable to the touch or to the eye, even on running the
fingers through the hair or combing or brushing the hair.
[0028] Although an exemplary embodiment of the invention has been
described above by way of example only, it will be understood by
those skilled in the field that modifications may be made to the
disclosed embodiment without departing from the scope of the
invention, which is defined by the appended claims.
