A method of attaching hair extensions to hair on a user's head includes attached a first plurality of wefts to hair in an upper section on a first horizontal side of a user's head. A second plurality of wefts is attached to hair in the upper section on a second side horizontal side of the user's head. A third plurality of wefts is attached to hair in the lower section on both the first side and the second side of the user's head. The wefts are of varying lengths and include extension hair of varying lengths.

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.

The present disclosure is drawn to weft hair extensions, and a method for attaching hidden rows of weft hair extensions to a wearer's natural hair. The hidden row of weft hair extensions is unexposed and undetectable on a wearer, allowing for a fuller, longer, more natural appearance.

An artificial hair fastening tool is provided which enables efficient operations of putting a human hair into a loop of an artificial hair and making a knot in the human hair for preventing the artificial hair from coming off. An artificial hair fastening method for fastening an artificial hair to a human hair efficiently and without imposing strain on the human hair is also provided. The artificial hair fastening tool includes: a front end portion having a spindle shape with a groove on a circumferential surface along a longitudinal direction and having a tip end on one end; and a rear end portion having a rod-like shape and extending from the front end portion toward an opposite side to the tip end.

A hair bundle, including: at least one hair; and at least one linear core material that is bundled together with the hair. The core material is capable of maintaining a deformed state when deformed together with the hair.

A hair accessory includes bundled synthetic braiding hair. The bundled synthetic braiding hair can include a first bundle of synthetic hair and a second bundle of synthetic hair strands. Other bundles with different lengths can be included as well. The first bundle and the second bundle can have different lengths and can be bundled at a common center, or alternatively can have a common length and can be bundled with their centers offset by a predefined distance. 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.

The present invention provides an artificial hair and a method for producing same. The method for producing an artificial hair according to the present invention comprises: a step of mixing polyamide 6 powder and a master batch at a predetermined weight ratio; a step of drawing an artificial hair from the mixture; a step of forming a loop part by knotting a distal end of the drawn artificial hair; a step of cutting the distal end of the artificial hair, leaving just 1-1.5 mm from the knotted part of the loop part; a step of trimming the artificial hair to a predetermined length after the cutting; and a step of bundling a plurality of the trimmed artificial hair.

The presently disclosed subject matter is generally directed to a pre-threaded needle assembly that can be used in the hair weaving process. Particularly, the needle assembly comprises a base around which a portion of thread is wound. The base is operably connected to a needle that is used in the weaving process. The assembly therefore includes a base pre-wound with thread such that the assembly can be immediately used (as compared to prior art needles that must be hand wound before use). The disclosed assembly therefore is pre-wound to save time and effort. The needle can further be pre-attached to the base to save even more time.
