[0005] Generally, the hair extension technology connects one or
more extension hair pieces to hair of a person or an animal. The
extension hair pieces are to make the person/animal's hair look
longer or thicker and/or add color accents to the person/animal's
hair. The extension hair pieces for hair extension are in various
forms and shapes, and include hair weaves, widgets, etc. In order
to attach hair extension to customer's natural hair, various
methods using metal tubes, double-sided tape, hair pins have been
used. Providing natural appearance and reducing user's discomfort
are the two key goals for hair extension attachment. Using less
material and reducing dimension of attaching means have always been
technological challenge. A thin, flexible yet strong bonding,
easy-to-remove hair extension has always been in need. The
foregoing discussion in this section is to provide general
background information, and does not constitute an admission of
prior art.
SUMMARY OF THE INVENTION
[0006] An objective of the invention is to provide a hair extension
with fixing tape that is light, thin and has strong fixing

layer.
[0012] The hair extension strip further comprises a second strip
adhesive layer between the glue layer and the one side of the hair
extension strip.
[0013] In another embodiment, the thin layer of hair strand is
contained in the hair extension strip.
[0014] The hair extension further comprises an attaching tape,
which comprises a first adhesive surface and a second adhesive
surface. The first adhesive surface is attached to the hair
extension strip, and the second adhesive surface is covered with a
non-adhesive liner strip.
[0015] The hair extension farther comprises a glue layer between
the first adhesive surface and the hair extension strip.
[0016] The glue layer is made of polyurethane or keratin. The glue
layer permeates to the first adhesive surface. Alternatively, the
glue layer is integrated with the first adhesive surface.
[0017] In still another embodiment, the hair extension strip
comprises a thermoplastic holding material that holds the thin
layer of hair strands.
[0018] The hair extension strip further comprises a first retention
mesh that retains softened thermoplastic holding material.
[0019] The hair extension strip may further comprise a second

retention mesh and applying thermoplastic holding material on the
second retention mesh.
[0024] Ultrasonic waves are applied on the hair extension strip.
The thermoplastic holding material consists of polyurethane or
keratin.
[0025] The advantageous effects of the present invention are: (1)
the hair extension strip is almost as thin as hair strands
themselves of the extension hair, thereby providing natural look
and better comfort for a customer; (2) the thin skin weft can be
attached to a customer's hair with various forms of fastening
devices; (3) urethane glue react with the adhesive surface of the
tape and provides firm bonding strength which is a way bigger than
that of the adhesive surface; and (4) when the hair extension is
removed with alcohol from a customer's hair, hair strands of the
extension hair maintain strong bonding with the hair extension
strip or the tape, thus there is no problem of incompletely removed
hair extension.
