A hair extension structure, configured to arrange at least one second hair bundle on at least one first hair bundle, is provided. The hair extension structure includes a spiral member and a fixing member. The first hair bundle passes through the spiral member and the fixing member. The second hair bundle is arranged on the spiral member and located at a periphery of the first hair bundle. The fixing member is flexible and arranged at an end of the spiral member to abut against the spiral member. The first hair bundle passes through the fixing member and is clamped when the fixing member is deformed.

A weft hair extension clip assembly, system, and method of using the same is provided. Each weft hair extension clip assembly has a planar base, along a first surface thereof the artificial weft hair is attached. On the second, opposing surface of the planar base is a frame joined thereto by opposing end caps for each clip of the weft hair extension assembly. Each end cap supports prongs movable between an inactive mode and an active mode, relative to the frame, where in the active mode the prongs intersect the plane of the frame in such a way as to urged hair of the user between the prongs and frame for a secure hold. The frame may also move in concert with the prongs from a convex configuration to a concave configuration hugging the head of the user in the active mode.

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.

Disclosed are a hairpiece, a hair extension structure, and a hair extension method that attaches a fake-hair bundle to a root position of a real-hair bundle to complete a hair extension. The hairpiece includes an inwardly folded fixing strip having fake-hair compositions with an upper end connected to the fake-hair bundle, and a thermosetting layer pre-combined with an inner side of the fixing strip. The hair extension structure has both fixing strip and thermosetting adhesive layer inwardly folded and the thermosetting adhesive layer covered and adhered onto both upper and lower sides of the real-hair bundle. The hair extension method includes measuring a user's head, preparing equal-division marks, grabbing the real-hair bundle according to the equal-division marks, covering and gluing the thermosetting adhesive layer of the hairpiece onto the real-hair bundle, and heating, melting, and solidifying the thermosetting adhesive layer to complete the hair extension structure of the hairpiece.

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.

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.

An eco-friendly crochet style synthetic braiding hair and its manufacturing method are disclosed. The synthetic braiding hair is comprised of a plurality of the first synthetic fibers configured to easily form a curly shape; a plurality of the second synthetic fibers configured to be half-length of the plurality of the first synthetic fibers and have a high elastic recovery to maintain curly shape; and a plurality of the combined synthetic fibers is made by plurality of the second synthetic fibers being combined in the middle of the plurality of the first synthetic fibers and folded together.

Hair enhancements, additions, and extensions that are, realistic, seamless, comfortable, secure, durable, and hygienic are disclosed. Embodiments include a hair product including a first layer, a second layer having an open weave structure, a third layer, the first and third layers encasing the second layer, and a plurality of strands of hair, each of the plurality of strands of hair being affixed to the second layer and extending therefrom. Other embodiments include a hair piece including a base comprising first, second, and third layers, the first and third layers at least partially encasing the second layer, and a plurality of strands of hair extending from the second layer. Various embodiments comprising different styles of hair enhancements are disclosed.

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.
