Abstract

Methods for styling, in particular for straightening, keratin fibers, in particular human hair, in which (i) a styling agent comprising carbocisteine and/or a salt thereof is applied to the keratin fibers and left there, (ii) the fibers, after a leave-in time, —are not rinsed, —are optionally dried, (iii) the fibers are mechanically deformed from exposure to heat, significantly minimize the negative consequences of styling and reduce in particular electrostatic charging and hydrophilization of the hair.
