The purpose of the present invention is to provide, in an emulsified base containing at least 5 mass % of water and a higher alcohol content, a hair cosmetic which imparts a desired shape, smoothness, and water repellency to hair and has excellent retention of this effect. The present invention relates to a hair cosmetic and a hair treatment method using the same, the hair cosmetic being characterized by containing: (A) a copolymer having, in a main chain thereof, a polysiloxane structure and a polyoxyalkylene structure, and having, in a side chain thereof, a trialkoxysilane group or a silanol group; (B) a surfactant containing one or two or more of (b-1) cationic surfactants in an amount of 2.0 mass % or less; (C) a higher alcohol; and (D) at least 5 mass % of water.

The invention provides a method of strengthening the fibres of oxidatively-treated hair, the method comprising the sequential steps of: (i) washing the oxidatively-treated hair; (ii) soaking the washed hair in an aqueous treatment composition, and (iii) drying the soaked hair; characterised in that the aqueous treatment composition comprises at least 1% N-acetyl glycine (by weight based on the total weight of the composition).15 The invention also provides the use of an aqueous treatment composition comprising at least 1% N-acetyl glycine (by weight based on the total weight of the composition), for the enhanced strengthening of oxidatively-treated hair fibres relative to virgin hair fibres.

The present disclosure relates to an active ingredient composition for shape change and surface modification of human hair. In particular, the present disclosure relates to a cosmetic agent for treating a keratinous material comprising a) at least one organic silicon compound and b) at least one thickener, the cosmetic agent being particularly suitable for treating colored hair.

The present disclosure relates to an active ingredient composition for the care and surface modification of human hair.
