Abstract
Method for simultaneously and permanently reshaping and coloring keratin fibers, particularly human hairs, in a single process in which the keratinic fibers are first waved by way of a foam-type waving agent (M1) and then lightened or colored by way of a foam-type coloring agent (M2). The permanent wave is simultaneously fixed by the oxidizing agent included in the oxidative dyeing agent. The method according to the invention brings about a uniform waving and coloring result and causes little or no damage to the hair.
