Abstract

A method for the permanent shaping and color modification of keratinic in a single process includes the following steps. First, an aqueous composition, including at least one keratin-reducing compound and at least one alkalizing agent, is applied to the keratinic fibers and is left on the keratinic fibers for a period of 5 to 50 minutes at a temperature of 20 to 45° C. The keratinic fibers are rinsed, and optionally dried. Next, a composition including at least one oxidation dye precursor and at least one oxidizing agent is applied to the keratinic fibers and the keratinic fibers are deformed. That composition is allowed to act for 10 to 35 minutes. An aqueous composition including at least one oxidizing agent, is applied to the keratinic fibers for 30 seconds to 15 minutes. The keratinic fibers are rinsed out, along with removal of the deformation aids.

First claim
