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.

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.

COMPOSITIONS AND PROCESSES FOR REFRESHING COLOR-TREATED HAIR A hair refreshing composition that accomplishes neutralization and / or toning in 5 minutes and includes a color-toning system with at least one direct purple-tone dye, and an acid-bonding restoring base that includes at least one anionic surfactant including an isethionate surfactant, at least one ester including coco-caprylate / caprate, at least one cationic compound, at least one additional surfactant, and a cosmetically acceptable solvent including water. The composition provides the dual benefits of restoring hair texture and toning and / or neutralizing hair color, particularly in lightened or color-enhanced blonde hair, in a formulation that is stable (maintaining viscosity, raw tone, and effectiveness in toning / neutralizing brassy tones).
