METHOD FOR CHEMICAL SMOOTHING OF HUMAN HAIRS

摘要

A method for reshaping, in particular for straightening, keratin-containing fibers, in particular human hair, in which (i) a pretreatment agent containing amino-functional silicone(s) with terminal hydroxyl group(s) is applied onto the keratinic fibers and left there, (ii) the fibers are optionally dried, (iii) the fibers are treated in the damp or dried state with a reshaping agent which, relative to the weight of the reshaping agent, contains 0.05 to 20 wt. % of alkali metal hydroxide(s), (iv) the fibers are optionally straightened with a comb or a brush during the reshaping treatment, (v) the fibers are shampooed with a shampoo which has a pH of 2.5 to 6.5, rinsed and neutralized, (vi) the fibers are optionally subsequently additionally mechanically deformed with exposure to heat, distinctly minimizes the negative consequences of reshaping, in particular electrostatic charging and hydrophilization of the hair.
