Abstract: The present invention relates to a hair cosmetic composition for cleansing and conditioning hair fibers, in particular human hair fibers, the hair cosmetic composition comprising anionic surfactants, amphoteric surfactants, thiol-based compounds selected from thiolactic acid, thiolactic acid derivatives, their salts, and mixtures thereof, thickening agents; nonionic surfactants; and water; wherein the pH of the composition ranges from about 2 to less than 7. The invention also concerns a method for imparting hair care benefits to hair fibers such as straightening effects, volume reduction, frizz control, manageability, cosmeticity, and smooth feel, in addition to cleansing and conditioning benefits and a use for hair care employing the cosmetic compositions of the present invention.

Abstract: The disclosure relates to compositions and methods for treating keratin fibers. Compositions comprise part (A) comprising (a) at least one compound chosen from urea and urea derivatives; and part (B) comprising (b) at least one polyol compound. Methods comprise applying the composition to keratin fibers to provide long-lasting effects such as good curl definition and regularity, better movement and discipline, and/or good volume and frizz control. Kits comprising the composition are also disclosed.

Abstract: The present invention relates to compositions for conditioning hair fibers, in particular human hair fibers, comprising (a) cationic surfactants; (b) thiol-based compounds; (c) fatty alcohols in an amount of from about 6% to about 20% by weight; (d) a component selected from polyols, fatty substances other than a fatty alcohol, and mixtures thereof; (e) water; and (f) optionally, neutralizing agents, wherein the pH of the composition ranges from 2 to less than 7. The invention also concerns a process for imparting hair care benefits to hair fibers such as straightening effects, volume reduction, fizz control, manageability, cosmeticity, and smooth feel, in addition to conditioning benefits and a use for hair care employing the cosmetic compositions of the present invention.
