Abstract: 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.

Abstract: 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.

Abstract: 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.
