Abstract

The subject of the invention is a composition and a method for permanent hairwaving, in which 1-thio-.beta.-D-glucose or its salts are used as keratin-reducing active ingredients. The composition affords a gentle and even shaping of the hair in a skin- and hair protective pH range of 7.0 to 8.5, without causing allergic and sensitizing reactions.
