Cosmetic agents for temporarily shaping keratin fibers, comprising a) a cosmetic preparation, including, based on the total weight of the cosmetic preparation, a1) 0.01 to 1.0 wt.-% of at least one hydrophobically modified metal oxide powder; a2) 0.01 to 0.5 wt.-% of at least one aminofunctional silicone; and a3) 40 to 95 wt.-% of water, are characterized by a high level of hold and volume.

System and methods for treating and shaping a keratin fiber are provided. A light-based system includes an activation system configured with one or more light source. The light source is configured to apply electromagnetic radiation at a target region including the keratin fiber. The light-based system applies the electromagnetic radiation to the target region to effectuate photocrosslinking with the assistance of a photosensitizer on the keratin fiber and transition the keratin fiber from a first physical state to a second physical state.

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.

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 means of a foam-type waving agent (M1) and then lightened or colored by means 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.
