A hair piece (1) comprises a foundation (3) having a boundary area (4) extending along a circumference (7); hairs (2) attached to the foundation; and at least one securing mechanism for securing the hair piece to natural hairs of its bearer. The securing mechanism comprises at least one slot (6) in the boundary area, which extends along the circumference and ends in the boundary area in both directions. An adhesive surface (8) extends from the slot towards the circumference. Hairs are attached to the foundation next to the adhesive surface in both directions of the circumference. A section (10) of self-adhesive hair band has an adhesive back to be glued to hairs of the bearer pulled through the slot and pressed against the adhesive surface. This section of self-adhesive hair band is permanently connected to the boundary area at that side of the slot opposite to the adhesive surface.

A hair system includes a thin skin hair unit having adhesive pre-applied to the inside surface, a sheet of silicone is located on a dome shaped form, and the hair unit is located on the form and silicone layer for storage, shipping to the client, and removal and use by the client.

An applicator for an artificial eyelash extension system having a plurality of filaments to which a first adhesive is disposed on a first surface thereof and to be attached to a user's natural eyelashes, the applicator includes: a tip portion having an adhesive area located on a predetermined portion of an upper surface thereof and a second adhesive applied to the adhesive area; and a tab portion connected to the tip portion and configured to be gripped by a user, wherein: a second surface of the filaments of the artificial eyelash extension system is temporarily fixed to the second adhesive, and a second adhesive strength of the second adhesive is smaller than a first adhesive strength of the first adhesive.

An eyelash extension includes an elongated base and a plurality of artificial lashes each attached to the elongated base. The plurality of artificial lashes is arranged in two or more clusters and each cluster includes two or more artificial lashes. The clusters are cinched together at a cinch point, which is spaced from the elongated base.

Replacement hair strands having a hair-joining element comprise a flat, thin platelet with one replacement hair strand embedded on an end of the platelet, and at least one thin rib that protrudes at an angle with respect to the strand direction of the replacement hair strand from one of two flat sides of the platelet. The rib has flat sides that taper toward its free end. The rib has a height and a base thickness, and the height is greater than the base thickness. The base thickness is approximately the same as a thickness of the platelet. The rib is configured to envelop natural hair strands longitudinally aligned with the strand direction of the replacement hair strand to securely connect the replacement hair strand to the natural hair strands.

A hair extension tape fixing tool includes two tape pressing plates and two pivoting half bodies that hold the plates. The elastic pressing plates are rectangular and have predetermined length, width and thickness. A method of attaching extension hair to a client's hair with the extension tape fixing tool includes steps of choosing strands of client's hair; bringing the tape patch of extension hair near the chosen strands of client's hair; positioning the strands of client's hair uniformly on the tape patch; and pressing the strands of client's hair on an adhesive surface of the tape patch with the hair extension tape fixing tool.

A hair extension comprises a plurality of extension hair strands and a hair extension tip that fixes the extension hair strands at one end of the extension hair strands. The hair extension tip comprises a flat thin body in which the extension hair strands are embedded and four parallel Protrusions formed on one surface of the flat body. The body has a rectangular shape, and the protrusions are aligned with the extension hair strands. The protrusion has a triangular cross-sectional shape having a height in a range from 1 mm to 2 mm. The hair extension tip is made of thermoplastic material.

A hair extension includes a section of hair and a substrate. Hair strands of the section of hair are affixed together at a first end by a solidified liquid polymer such that ends of the hair strands are retained within the polymer across a width of the section of hair. The substrate is attached to the polymer on one side (e.g., a rear side) of the section of hair across at least part of a width of the hair section. According to one exemplary embodiment, the substrate is also a solidified polymer. The width of the substrate, as measured along a length of the extension's section of hair, is substantially greater than a width of the polymer, as similarly measured. The wider substrate facilitates reliable attachment of the extension to the user's hair, while the narrower polymer enables the installed extension to remain virtually undetectable.

The invention relates to a hair extension. In a preferred embodiment, the hair extension comprises strands that are attached together in such a way as to provide a substantially flat configuration, such that opposed sides are defined. This helps the hair extension to lay flat against a person's head. The opposed sides may have different hair colours on them, allowing flexibility and additional styling options. Preferably, the aligned hairs are compressed into a narrowed tip section, which is used to fasten the hair extension to a person's natural hair, using a deformable member such as a micro ring. A method of manufacturing the hair extension, and a method of attaching the hair extension to a subject, are also disclosed.

An improved hair extension includes a base portion that is oblique with respect to a horizontal reference. The hair strands coupled to the base portion define an oblique (e.g., non-perpendicular angle) with respect to the base. In this configuration, the hair strands fall vertically while the base is angled. This prevents undue stresses in the hair and in the base due to bending when traditional hair extensions are placed in a tilted manner and reduces unwanted bumps due to these inflection points.
