Abstract

Abstract A method for the permanent shaping of hair, in which the hair is treated with an aqueous preparation of a keratin-reducing substance before and/or after a mechanical shaping step, rinsed with water and fixed by treatment with an aqueous preparation of an oxidizing agent and rinsed with water, wherein, after the oxidative fixing step, the mechanically shaped hair is aftertreated with an aqueous composition comprising a dissolved aluminium (III) salt and a hydroxydi- or tri-C4-6-carboxylic acid; the novel composition itself; and a kit for effecting such method.
