Provided are adhesive compositions that include an acrylate component and a charcoal component. The adhesive compositions are useful for adhering articles, for example, lashes or lash extensions to surfaces such as skin.

A cosmetic treatment method. The method includes creating, on a region of the keratin materials to be treated, a set of adhesive areas and of non-adhesive areas extending between the adhesive areas. The method includes electrostatically projecting fibres onto the region.

An apparatus for curing adhesive gels used for lash and hair extensions. A housing includes a flexible tube extending from the front of the housing. An LED lamp is affixed within the flexible tube for illuminating a target area in front of the tube. A circuit is configured to drive the LED lamp. A front wedge is affixed to the bottom of the housing for holding and guiding a pair of tweezers for operation in the target area, and a rear wedge is affixed to the bottom of the housing in alignment with the first wedge for holding the back end of the pair of tweezers.

Problem

Provided is a practical hair extension configured to be very easily attached to head hair (natural hair) and attachment of which on the head hair is less likely to be noticed by other people.

Solution

A hair extension 1 includes a base member 2, a first hair bundle H.sub.1, a second hair bundle H.sub.2, a double-sided adhesive tape 3, and a release paper 4. The first hair bundle H.sub.1 is secured to a lower side of an inner surface of an approximately rectangular plate-shaped base member 2 in a state where hair ends are projected downward. The second hair bundle H.sub.2 is secured to an upper side of the inner surface of the base member 2 in a state where hair ends are projected upward, and the second hair bundle H.sub.2 is folded back at an upper end edge of the base member 2 having the hair ends drooped downward.

A removable device for temporary attachment to the head of a person having native hair, said device comprising a base and a substrate, said base comprising a top surface and a bottom surface and a plurality of nonnative hair pieces secured thereto and extending outward from said top surface, said base having a generally crescent shape comprising a center portion and at least two side portions extending outward from said center portion, said side portions aligned generally parallel to one another when attached to the head of a person, said substrate comprising a top and a bottom surface having a shape similar to at least a portion of the shape of said base, and at least one of said bottom surface of said base and said top surface of said substrate adapted to receive an adhesive.

Hair replacement piece (1) consisting of an essentially oval or polygonal flat structure (2) with embedded replacement hairs comprising in the area of its boundary a localized circumferential thread (3) attachable to one's own hair by hot-melt bonding. In order to enhance the seat and prolong the fastening period of the hair replacement piece at least one additional fastening thread (4) is provided which is connected to the thread (3) with at least on of its two ends (5;6) and runs loosely.

The present disclosure is directed to systems and methods for supplementing human hair. A system and method includes a wire coupled to an existing hair, wherein the wire pulls the existing hair through a funnel and microtube. A sleeve with supplemental hairs is positioned on the microtube and configured to be coupled to the existing hair. After the existing hair passes through the microtube, the wire, funnel, and microtube are removed, thus leaving the supplemental hairs coupled to the existing hair via the sleeve. An alternative system and method includes one or more tools for installing two halves of a sleeve with supplemental hairs extending therefrom onto a strand of existing hair. The one or more tools are configured to guide the strand of existing hair into engagement with the halves of the sleeve, thus securing the sleeve and the supplemental hairs on the strand of existing hair.

A tool for removing an adhesive from a hair weft includes a base portion having a first region with an interior surface, and a second region; a partial covering portion having a first region with an access aperture exposing the interior surface of the base portion, and a second region; a pivotable hinge coupling the base portion and the partial covering portion and configured to allow the base portion and the partial covering to bias relative to each other; and a containment aperture configured to hold a roll of a fabric therein, the aperture at least partially bounded by the second region of the base portion and the second region of the partial covering portion.

A seamless hair extension method, more particularly a seamless fast hair extension method for fast performing hair extension in a painless manner, includes a native hair processing step, a to-be-extended hair processing step, an adhesive bonding step, a bundle bonding step and a trimming step, so that the hair extension step and time can be shortened, and a hair extension effect is firm. Moreover, because they are radially serially connected into one piece, every bundle of hair is arbitrarily movable at a hair root, and no discomfort pain is caused by the long time of usage. Meanwhile, the scalp disease cannot be caused, and the personal scalp health can be promoted.

Extension devices for attaching hair extension elements to artificial hair elements that protrude from a subcutaneously implanted hair implant anchor body. One extension device involves a cylindrical structure having respective cavities on opposing ends. One cavity receives the distal end of the artificial hair element while the other cavity receives the hair extension therein. Another extension device involves a hair extension element forming a first portion of the device while a second opposite portion includes a projection that is received inside a hollow interior of the artificial hair element. A third extension device involves a core having a hair extension element projecting from one side of the core while a single cavity is located on a second side, opposite the one side, and which receives the distal end of the artificial implanted hair element therein. The hair extension may comprise ancillary hair elements and bud structures. Ornamental structures may be included on the distal ends of the hair extension element.
