Disclosed herein is a device which supplements an amount of hair on a human head. More specifically, the device allows a wearer to give an appearance of having a fuller thicker head of hair while the use of the device is undetectable to others. That is, the device enhances desirable aesthetic characteristics of hair in manner that makes the hair appear to be part of the wearer's natural hair growth.

A hair accessory has a helical elastic band that forms a closed circle. The hair accessory also has a weft having a hair retention member and a plurality of strands that extend from the strand retention member. The weft is spirally wrapped around the elastic band so that the weft completely encases the helical elastic band and allows the helical elastic band to move between an enlarged configuration and a contracted configuration. The helical elastic band is biased to the contracted configuration.

A synthetic braiding hair and its manufacturing method are disclosed. A synthetic braiding hair creating a faux locs style and a bohemian hair style simultaneously is comprised of the plurality of the first synthetic fibers spirally wound to create a faux locs hair style, the plurality of the second synthetic fibers spirally wound simultaneously along the plurality of the first synthetic fibers and extended at one end longer than the plurality of the first synthetic fibers to create a bohemian hair style thereof, and a hook formed at the other end of the plurality of the first synthetic fibers.

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.

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 hair bundle apparatus is provided. The hair bundle apparatus includes: a first section comprising a loop member, a first end and a second end, wherein the first section is constructed of a first material comprising one of synthetic hair, an elastic band, wire, and thread; a second section comprising a locking member; and a third section comprising a third end and a fourth end, wherein the third section is constructed of a second material comprising human hair.

A hair extension device is provided having a first piece having a first attachment portion and a weft portion. The hair extension device can have a second piece comprising a second attachment portion. The first and second attachment portions are configured to be pressed against each other with the wear's hair intertwined there between. One or more wefts of filaments are attached to the backside of at least one of the first or second attachment portions.

A two-piece hair extension device is provided having a first piece comprising a first attachment portion and a weft portion and second piece comprising an second attachment portion. The first and second attachment portions are configured to be pressed against each other with the wear's hair intertwined there between. One or more wefts of filaments are attached to the backside of at least one of the first or second attachment portions.

A hair accessory includes bundled synthetic braiding hair. The bundled synthetic braiding hair can include a first bundle of synthetic hair strands having a first length, a second bundle of synthetic hair strands having a second length that is shorter than the first length. Other bundles with different lengths can be included as well. A binder can be coupled about a waist of the bundled synthetic braiding hair. When the bundled synthetic braiding hair is folded about the binder, the different strand lengths work to define a substantially cardioid shaped perimeter of the bundled synthetic braiding hair.

A hair extension device is provided having an attachment portion and a weft portion. The attachment portion has a front side having headed studs extending therefrom. One or more wefts of filaments are attached to the backside of the attachment portion.
