For obtaining a natural-looking hair without excessive volume compared with traditional hair extensions, there are provided a hair extension and manufacturing & attaching method of the same, comprising a linearly extending base member (200); a plurality of hair extension strands (300) to be provided longitudinally along the base member (200), each of the plurality of hair extension strands (300) including a knot part (310) being a knot formed on the base member (200) and a hair part (330) extending from the knot part (310); and a fixing part (400) to be fixed to a portion of the hair part (330) so as to be adjacent to the base member (200) for connecting the plurality of the hair extension strands (300) to the hair of a subject.

An enhanced apparatus and method are provided for adding length and bulk to natural hair using hair extensions comprising an elongated strip having a plurality of apertures through which natural hair is pulled, the natural hair threaded into a bead which adhesive qualities after threading.

A hair extension anchor fastening device includes hair anchor tubes, which has a tube wall. The tube wall includes a top opening, a bottom opening, a first hole and a second hole that is opposite to the first hole. A wire passes through the holes of the hair anchor tubes whereby the hair anchor tubes can slide along the wire. Hair fixing devices are provided. The hair fixing device includes a bead thread forming a loop and a bead handle that connects both ends of the bead thread and the bead thread passes through the hair anchor tube. The device may be provided as attached to a hair weft by sewing a hair weft band through the holes of the tube wall or sewing the wire to the weft band.

A method is provided for attaching a hair extension to a recipient's hair. The method comprises defining an anchoring structure for receiving attachment of the hair extension; positioning the hair extension adjacent to the anchoring structure; employing a hair extension attachment apparatus to attach the hair extension to the anchoring structure; wherein the employment includes manipulating a user manipulable hand member of the apparatus to position a shield mechanism between the recipient's scalp and the fastener as the fastener is being crimped; and to crimp a fastener to attach the hair extension to the anchoring structure. An apparatus is provided for attaching a hair extension to the recipient's hair. The apparatus comprises a mechanism for crimping a fastener to attach the hair extension; and a shield mechanism for preventing the fastener from contacting the recipient's scalp as the fastener is being crimped.

A skin weft hair extension includes an extension tip that fixedly holds a plurality of extension hair strands and a metal tube that is detachably assembled to the extension tip and fixes the skin weft hair extension to hair strands of a customer. The extension tip comprises a receiving device that receives and detachably holds the metal tube. The receiving device comprises a narrow-width portion that pass through the hair fixing tube, a stopper portion that is provided at one end of the narrow-width portion, which prevents the metal tube from falling off, and a hair holding portion that is wider than the narrow-width portion. The hair holding portion is provided at the other end of the narrow-width portion.

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 method of attaching hair extension to customer's hair includes steps of forming beads with strands of customer s hair using bead forming devices and attaching hair extension to the beads using a hair extension attachment device. The hair extension attachment device includes a weft that holds extension hair strands, an attachment thread fixed to the base weft, an attachment needle fixed to a free end of the attachment thread. The bead forming devices includes a bead tube, a first bead thread that passes through the bead tube, a first bead handle that connects both ends of the first bead thread, a second bead thread that passes through the bead tube and a second bead handle that connects both ends of the second bead thread. The bead tube is positioned between the first bead handle and the second bead handle.

Apparatus and associated methods relate to two or more hair wefts defined by respective filamentous cortices to which hair is secured, which cortices are secured together along their length by at least one binding filament, and to which cortices are coupled an elastic filament to form a hair extension configured such that the cortices and elastic filament are configured to circumscribe a wearer's head. In an illustrative example, a plurality of deformable beads may be disposed between the hair wefts and configured to releasably secure the hair extension to a wearer's natural hair. Each hair weft may, for example, have a plurality of individual hair bundles. Hair bundles may, for example, be separated by a predetermined cut point in the filamentous cortex. Various implementations may advantageously provide a visually undetectable, comfortable, and durable hair extension for a wearer.

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 system having a sleeve, a rod, a microtube, a transitional member, and an acceptance member. The rod is sized and shaped to have an outer diameter that is smaller than a width of an existing hair and configured to accept the sleeve. The transitional member is sized and shaped to enable the sleeve to be slid from the rod and stretched onto the microtube. The microtube is sized and shaped to accept the existing hair and the sleeve. The acceptance member is sized and shaped to enable the existing hair to be positioned into the microtube. When the sleeve is slid off the microtube and onto the existing hair, the sleeve constricts towards its original diameter, thus gripping the existing hair.
