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 hair bundle 2, a double-sided adhesive tape 3, and a release paper 4. The hair bundle 2 has a base end including a first hair layer L.sub.1 formed by laterally aligning a plurality of hairs h.sub.1, h.sub.1 . . . such that base end edges of the plurality of hairs are linearly arranged and bonding vicinities of the base ends of the hairs h.sub.1, h.sub.1 with an adhesive so as to have a constant adhesive width, and a second hair layer L.sub.2 formed by laminating a plurality of hairs h.sub.2, h.sub.2 . . . to be laterally aligned on an upper side of the first hair layer L.sub.1 such that base end edges of the plurality of hairs are linearly arranged and bonding vicinities of the base ends of the hairs h.sub.2, h.sub.2 . . . with an adhesive so as to have an adhesive width narrower than the adhesive width of the first hair layer L.sub.1. Furthermore, the double-sided adhesive tape 3 is stuck to the first hair layer L.sub.1.

A biodegradable hairpin contains: a first clip, a second clip, and a C-shaped flexible retainer. The C-shaped flexible retainer includes a first leg, a second leg, an opening, a peak portion, a first shoulder, and a second shoulder. An inner wall of the C-shaped flexible retainer extends to the first leg and the second leg from the peak portion along a parabolic track, such that a thickness of a cross section of the peak portion is 1.666 times more than a thickness of a cross section of the first leg and a thickness of a cross section of the second leg. The biodegradable hairpin is made of any one or a combination of at least two of Bio-Polybutylene Succinate (PBS), Polylactic acid (PLA), D-polylactide (PDLA), toughener, and nucleating agent, such that the biodegradable hairpin has ductility, malleability, and toughness.

A method of attaching hair extensions includes sectioning, beading, securing, and stitching hair extensions into a client's hair. Sectioning allows a hairdresser to properly place the hair extension, which creates beads that are unseen. The beads may be placed so as to allow a flexible groove to place the wefts. Securing the wefts includes a pattern of stitching that places a stitch at a side, middle, opposite side, and between the beads. This stitching pattern promotes secure wefts as well as prevents damage to scalp and hair.

A method for attaching a hair extension to natural hair of an individual includes threading portions of natural hair through a first mesh and a fixing element. The first mesh including a first grid-based mesh with two or more openings and two or more first portions of snap buttons, where the natural hair is threaded through the two or more openings. The method further includes positioning the first mesh against the scalp, fixing the first mesh to the portions of natural hair with the fixing element positioned against the mesh, and fastening, with the snap buttons, a second mesh to the first mesh. The second mesh includes a second grid-based mesh with hair extensions affixed thereto, and two or more second portions of the snap buttons fixed to the second grid-based mesh where the first portions of the snap buttons align with the second portions of the snap buttons.

Apparatus and associated methods relate to a hand-tied hair weft having at least two hair bundles fixed to three or more thread-like filaments that provide a cortex, where each two adjacent hair bundles are separated by one or more knots formed by the three or more thread-like filaments. In an illustrative example, the two adjacent hair bundles may be separated by, for example, at least two knots. The knots may include overhand knots. By introducing one or one or more knots, the width of the hand-tied hair weft may be customized without the weft shedding or unraveling.

A method of installing and attaching a hidden row of hand-tied natural human hair extensions onto the wearer's hair to supplement hair thickness, volume, and length, wherein the method minimizes stress and tension on the wearer's hair and scalp, thereby increasing comfort and reducing adverse scalp health impacts.

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.

A hair extension system is a system that enables users to make their own custom hair extensions in any style or design. The system serves as a kit that includes the tools and materials necessary for the user to make their own custom-made hair extension. The system also facilitates the attachment of the custom hair extensions to the user's head. The system may include a fabric backing, a plurality of adhesive strips, and at least one hair-attachment mechanism. The fabric backing supports the structure of the custom hair extension and increases the comfort of wearing the custom hair extension. The plurality of adhesive strips facilitates the making of the custom hair extension by enabling the attachment of hair wefts onto the fabric backing in a simple manner. The at least one hair-attachment mechanism secures the custom hair extension to the user's head so that the user can perform everyday activities.

A hairpiece with identical front and back appearances includes a first hair layer, a support layer, and a second hair layer, where the support layer is located between the first hair layer and the second hair layer; and the first hair layer and the second hair layer are fixedly connected to the support layer. In the hairpiece, since the front and back sides of the hairpiece have the same appearance, the user can wear the hairpiece directly, without bothering to distinguish the front and back sides. This avoids the risk of reversing the front and back sides of the hairpiece, and improves the aesthetics and delicacy of the hairpiece.

A hair weave stand for unweaving, repairing, refurbishing and weaving hair is shown. The hair weave stand is useful for an easier and space efficient device for unweaving, repairing, replenishing and weaving a hair weave. Also, the hair weave stand is portable and requires less storage space, has a much smaller footprint when using than when performing those tasks currently.
