The instant disclosure relates to methods for removing color from artificially colored hair. The methods include a two-step process: (I) applying a reducing composition to hair that has been colored with oxidation dyes and rinsing the reducing composition from the hair; and (II) applying an alkalizing composition to the hair and rinsing the alkalizing composition from the hair. The step can be carried out in either order. The methods effectively remove color from artificially hair in a quick and gentle manner without employing an oxidizing agent.

PROCESSES AND COMPOSITIONS FOR TREATMENT OF BLEACHED OR OXIDATIVELY COLORED HAIR This disclosure relates to processes and compositions that may be used at home to treat bleached or oxidatively colored hair. The processes include: (i) applying a strengthening composition to the colored or oxidatively bleached hair, the strengthening composition comprising citric acid, one of its salts, or a combination thereof, cyclodextrin, one of its derivatives, or a combination thereof, one or more polyols, and water; and (ii) without rinsing the strengthening composition from the hair, applying a conditioning composition to the hair, the conditioning composition comprising: one or more cationic surfactants, one or more non-silicone fatty compounds, one or more silicone oils, and water.The processes strengthen hair, improve curl retention, prevent frizz, and repair damage caused by bleaching or chemical coloring.

The disclosure provides a grey hair removal component, and a grey hair removal comb and a grey hair removal system composed of several grey hair removal components. The grey hair removal component includes at least one housing, and at least one identification unit and a grey hair removal unit arranged within the housing (0), and further includes a sensing unit arranged at an end of the housing, and the sensing unit responds to the contact of the component with a scalp and outputs a start signal; the identification unit identifies a grey hair in response to the start signal and outputs a removal signal; and the grey hair removal unit removes the identified grey hair based on the removal signal. By means of using the grey hair removal component and the grey hair removal system to scan the surface of the entire scalp (9), the aims of removing all grey hair and leaving colored hair can be achieved, and enhancing the personal appearance of a user.

COMPOSITION FOR KERATINOUS FIBERS The present invention relates to a composition for keratinous fibers, comprising: (a) at least one oxidizing agent; (b) at least one oil and (c) at least one branched hydrocarbon compound different from the (b) oil, wherein the amount of the (c) branched hydrocarbon compound is 0.1% by weight or more, based on the total weight of the composition. The composition according to the present invention can bleach or color keratinous fibers such as hair, while also improving the hand feel of the bleached or colored hair, even without the aid of cationic polymers.

The invention relates to the technical field of textile fiber material modification and wig manufacturing, and discloses a yak hair bionic human hair material based on tannic acid cross-linking modification and a preparation method thereof.The preparation method comprises the following steps that raw material pretreatment is conducted, specifically, healthy and stain-free yak hair raw materials are selected, preferably, fine and soft hair of the yak abdomen is selected, and the raw materials are pretreated; the method comprises the following steps: cleaning and degreasing to remove surface grease and impurities, rinsing with a warm water solution of a nonionic surfactant, fully rinsing with clear water, naturally airing or drying at low temperature, and bleaching as required to remove natural pigments, thereby obtaining the clean light-colored hair raw material. Through hexafluoroisopropanol pretreatment, keratin scale structures on the surfaces of yak hair fibers are swelled and recombined, and original rough scales which are loosely arranged and have a small stacking number become flat and ordered. A layer of flexible and uniform organic thin film is further formed on the surface of the fiber through the subsequent tannic acid cross-linking coating step, and the original rough texture of the yak hair is thoroughly changed.

It is provided a kit for obtaining a hair coloring composition, a hair coloring composition, and a method for treating hair. The hair coloring composition particularly provides the desired color shade and intensity, together with an enhanced root to tip evenness on hair, particularly on previously colored hair and on hair with a broad range of damage levels along hair length.

The present invention relates to a method for removing color from hair keratin fibers, comprising applying at least one color removing composition to hair keratin fibers that have been previously colored using at least one hair coloring composition, the at least one hair coloring composition comprising at least one (poly)carbodiimide compound; and at least one colorant selected from pigments, direct dyes and mixtures thereof; said color removing composition comprising at least one glycol ether; and optionally at least one alkyl or alkylene carbonate.

The present invention provides a first-agent hair dye composition that dyes light-colored hair a vivid primary red color, exhibiting high red color saturation and excellent colorfastness. [Solution] A first hair dyeing agent composition containing one or more selected from (A) 1-hydroxyethyl-4,5-diaminopyrazole, (B) 2,6-diaminopyridine, and (C) 5-(2-hydroxyethylamino)-2-methylphenol or m-aminophenol, wherein the mass ratio of component (C) to component (B) [(C) / (B)] is 0.10 to 0.80.

Included herein are methods and materials for nontoxic, biocompatible, optionally metal-free, tunable, and long-lasting coloration of human hair. More particularly, provided herein are methods, and associated formulations, for efficient formation and deposition of synthetic melanin to human hair, thereby coloration of hair, whereby the hair treatment formulation is viscous enough for treatment of hair without substantially loss of the formulation which further allows an easier application process that includes exposing the hair to the treatment formulation for an extended amount of time. For example, the hair treatment formulation, or viscous solution, can be applied and left on the hair, such as if it were a cream or gel, without requiring soaking the hair in a bath. Different colors can be achieved by tuning reaction conditions such as temperature and solution phase composition. These methods, and associated materials, can be used in salons and at home, for example, without degradation of the resulting colored hair and safety of the user of the present materials and methods.

COMPOSITION FOR KERATINOUS FIBERS The present invention relates to a composition for keratinous fibers, comprising: (a) at least one oxidizing agent; (b) at least one oil; and (c) at least one branched hydrocarbon compound other than (b) the oil, wherein the amount of (c) the branched hydrocarbon compound is 0.1% by weight or more, relative to the total weight of the composition. The composition according to the present invention can bleach or color keratinous fibers such as hair, while also improving the feel of bleached or colored hair, even without the aid of cationic polymers.
