A method for the permanent shaping and color modification of keratinic fibers, in a single process, includes the following method steps in sequence:deforming keratinic fibers, using deformation aids,applying an aqueous composition, including at least one keratin-reducing compound and at least one alkalizing agent, to the keratinic fibers situated on the deformation aids, and leaving this composition for a period of 5 to 50 minutes,rinsing the keratinic fibers situated on the deformation aids,applying a composition, including at least one oxidation dye precursor, at least one oxidizing agent, at least one alkalizing agent, and at least one surfactant, as foam from an applicator to the keratinic fibers situated on the deformation aids, and leaving this composition for a period of 10 to 45 minutes,removing the deformation aids from the keratinic fibers and rinsing the keratinic fibers, andoptionally applying an aftertreatment agent to the keratinic fibers.
