Various methods are used to attach a hair extension to a user's natural hair, where the hair extension may include a section of hair that is secured together across its width proximate one of its lengthwise ends and is free hanging at its other lengthwise end. According to one such attachment method, a first adhesive is used to attach together a first side of the hair extension's secured end and a first section of the user's natural hair. A second adhesive is used to attach together a second side of the hair extension's secured end and a second section of the user's natural hair. Upon completion of both attachments, the hair extension is positioned between and adhered to the first and second sections of the user's natural hair. Each adhesive may be double-sided adhesive tape and may be pre-attached to its respective side of the hair extension's secured end.

A portable hair weave drying device utilizing an external heat or vacuum source is provided. Such a device includes three basic components that are configured to provide an enclosure and internal stand for hair weave placement during such a drying operation. A base for placement of such an internal stand and an ingress port is provided as well, with the port disposed at a bottom location of the overall device for insertion of a heat source (hair dryer nozzle, for instance) or vacuum source (a wet/dry vac nozzle, again, for instance) with an adapter to ensure a snug fit therein. A dome is further provided to place over and around the internal stand and contacted with the base to fully enclose the internal stand (and thus hair weave placed thereon during utilization) and having at least one controlled vent to allow for moisture and hot air to exit during operation.

Protein fibers for artificial hair include a polycation, wherein the protein fibers for artificial hair are crosslinked with an organic compound and/or a metal salt, and the protein fibers for artificial hair have curls. A method for producing the protein fibers for artificial hair includes treating artificial protein fibers that are crosslinked with an organic compound and/or a metal salt with a treatment solution containing a polycation, and curling the artificial protein fibers, or curling artificial protein fibers that are crosslinked with an organic compound and/or a metal salt, and treating the curled artificial protein fibers with a treatment solution containing a polycation.

A hair extension bar comb retains hair for a coloration or treatment process on an elongated base. In one embodiment, first and second comb teeth rows are respectively mounted in parallel on corresponding laterally spaced apart parallel side regions of the base (typically on a top flat base surface). In use, some teeth of at least one comb teeth row captures extension hair therein. A coloration/treatment process is engaged on captured extension hair in the lateral space between the first and the second comb teeth rows. A floor or table stand may be provided with a mounting coupler on the bottom of the base. A hair extension storage bag is elongated, defining a vertical bag cavity with an upper edge lip closure system. A horizontal bar with a single comb teeth row is mounted in the upper region of the bag cavity. Comb teeth capture extension hair which falls down into the vertical bag cavity. A vertical closure system is also included.

Implementations of a hair extension washboard are provided. In some implementations, the hair extension washboard comprises a hair extensions board, a hair clip assembly, and a board support. In some implementations, the hair extension washboard further comprises a hair drying enclosure. In some implementations, the hair extension washboard also comprises surface connectors.

In some implementations, a method of using the hair extension washboard comprises positioning the hair extension washboard in a sink or other suitable location, holding hair extensions with the hair extension washboard, and washing, coloring, drying, etc. the hair extensions while held by the hair extension washboard.

A conjugate fiber including a core part and a sheath part covering the core part such that the conjugate fiber has a core-to-sheath area ratio of core:sheath=2:8 to 7:3 and an eccentricity of 5% or more in a cross section thereof. The cross section is in a multilobed shape and has a major axis of length L and a first minor axis of length Si y satisfying a ratio of L/S1 being 1.10-3.00. The core part has a major axis of length Lc and a first minor axis of length Sc satisfying a ratio of Lc/Sc being 1.10-3.00. The major axis of the core part is in a direction that substantially coincides with a direction of the major axis of the cross section.

Certain embodiments of the disclosure may include devices, systems and methods for carrying hair pieces and coupling the hair pieces to an embodiment of the disclosure. According to an example embodiment of the disclosure, a hair carrying device can include a collapsible container having an internal surface and an external surface. The internal surface can include a top internal surface side, and external surface can include a top external surface side. The top internal surface side and the top external surface side can be coupled and define an opening comprising an area. The embodiment can also include at least one clamping device coupled to the internal surface.

Embodiments of the present teachings address torn hair from a person's scalp when receiving hair extensions by absorbing the mechanical stress of affixing such hair weft extensions to a person's scalp. The hair weave apparatus of the present disclosure comprises a first side, adapted to be affixed to a plurality of hair wefts, a second side, adapted to be affixed to a plurality of hair braids organized in parallel, and a plurality of apertures.

A drying cabinet has a housing; a door; a carousel drying rack rotatably mounted within the housing; a heat protecting cap; a heating element; a blower mounted in a diagonal configuration; and a controller. The housing includes a top surface with a hole, a base, a front wall with a loading opening, a rear wall, and two sidewalls, forming an inner chamber. The door is hingedly mounted to the front wall, to close the loading opening. The drying rack is a ring having an upper surface, a lower surface, a perimeter, and suspension appendages extending from the lower surface. The cap has a handle and is removably mounted within the top hole. The controller is mounted within one of the sidewalls and has a user interface to selectively operate the heating element and/or the blower. The blower outputs air at a predetermined angle to spin the hair while drying it.

The proposed invention is uniquely configured to allow for the efficient organization, storage and use of hair extensions in a salon setting where it can easily fit into a typical salon work station or cart. The two-piece book design allows for ease of operation and transport as well as the stacking of multiple cases. The specialized cut-out sections in each end of invention facilitate direct access to the attachable end of a hair extension and allow for the storage of longer hair extensions when the invention is closed. The vertical pin arrangement on the interior of the invention prevents damage to the hair extensions and keeps them organized, lying flat and separated. These design elements help the stylist to stay organized and work quickly and efficiently. Because the invention can be easily cleaned and sanitized, it can be manufactured to meet most, if not all, state cosmetology sanitation codes.
