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 colors 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.

A human hair implant procedure involves inserting a length of barbed surgical thread through a cannula so that a first portion including a distal end of the barbed surgical thread is near a distal end of the cannula and a second portion is outside the proximal end of the cannula, then inserting the distal end of the cannula through an entry point of the skin of the human and advancing the cannula under the skin until the proximal end of the cannula is near the entry point of the skin. Then, removing the cannula from under the skin, leaving in position under the skin the first portion of barbed surgical thread which secures a hold to tissue under the skin, and finally, attaching hair to the second portion of barbed surgical thread.

Apparatus and associated methods relate to refreshable hair weft installation structure. In an illustrative example, the structure includes a bead placement. The bead placement, for example, may include N anchor beads disposed from an end of a hair parting line until a longitudinal line of one side of a user's head along a first latitudinal contour at a distance x1 below the hair parting line. For example, the bead placement may also include M foundation beads disposed between the N-th anchor beads and a back of the user's head along a second latitudinal contour above the first latitudinal contour. The anchor beads are attached to a hair weft with a surface stitch tying only wefts and multiple backward stitches tying the wefts with a hair pocket of the anchor beads. Various embodiments may advantageously remove stress around the anchor beads and/or provide a refreshable edge without re-installation of the wefts.

A method of integrating a hair extension weft on a human scalp is disclosed. The hair extension weft includes a polyurethane strip enclosing a plurality of meshes arranged in a longitudinal direction of the strip. Each mesh is configured to have a plurality of contiguous hairs attached in a transverse orientation. The hair extension weft includes several gaps formed between the plurality of meshes in the longitudinal direction. Each gap is configured to receive a plurality of hairs from the human scalp. Upon clipping the hair extension weft to the human scalp, the plurality of hairs is pulled through each gap with a needle shaped tool placed under the each gap of the hair extension weft. A microbead is clamped to the plurality of hairs pulled through the each gap, to anchor the hair extension weft to the human scalp.

A handheld tool attaches hair extensions. The tool has two hand members. The members are mechanically coupled to each other and moveable with respect to each other. The tool includes a fastening mechanism. The fastening mechanism is configured to crimp a pliable material to form a fastener that attaches the hair extension to the recipient's hair. The tool includes a shield mechanism, which is coupled to one hand member. The shield mechanism includes safety feet having first and second positions. The shield mechanism is in the first position when the apparatus is in a quiescent position, and the shield mechanism is in a second position when the fastening mechanism is crimping the fastener. In the second position, the feet are interposed between the recipient's scalp and a cornrow of the recipient's hair. The safety feet move from the first position to the second position as the fastener is being crimped.

A system having a sleeve with a circumscribing sidewall formed of elastic, compliant material, the sleeve having an internal axial bore sized to have an inside diameter equal to or less than an outside diameter of a host hair to be received in the bore, the sidewall formed of thermoplastic resilient, compliant material, and at least one supplemental hair embedded in the sidewall or attached to the sidewall of the sleeve.
