Abstract: A method for dyeing keratinous fibers, in particular, human hair, in which, after a thickened pre-treatment agent (M1) containing no oxidation dye precursors has been applied and allowed to react, a coloring agent (M2) is applied and allowed to react immediately thereafter and without rinsing.

Abstract: A method for the oxidative dyeing of keratinic fibers includes the following steps: applying a cosmetic agent (M1) to the keratinic fibers, allowing agent (M1) to act on the keratinic fibers for a time period of 30 seconds to 40 minutes at a temperature of at least 25° C., applying a cosmetic agent (M2) to the keratinic fibers treated with cosmetic agent (M1), allowing cosmetic agents (M1) and (M2) to act on the keratinic fibers for a time period of 1 to 70 minutes, and rinsing out of cosmetic agents (M1) and (M2). Cosmetic agent (M1) includes at least one oxidation dye precursor of the developer type (M1-1), at least one oxidation dye precursor of the coupler type (M1-2), at least one direct dye (M1-3), and at least one surfactant (M1-4).

Abstract: A method for dyeing keratin fibers, in particular human hair, in which, after a thickened pretreatment agent (M1) including at least one oxidation dye precursor has been applied and left to act, directly thereafter and without rinsing a coloring agent (M2) is applied and left to act. By virtue of this method, in one dyeing step the hair can be colored and at the same time a multi-tonal dyeing with lighter (“highlights”) or darker (“lowlights”) sections (strands) can be produced.

Abstract: Cosmetic agents for simultaneously lightening and temporarily shaping keratin fibers include a specific thickener and also at least one oxidant and have a viscosity of from 31,000 to 90,000 mPas. Despite the high viscosity, the agents can be easily removed from the packaging and moreover can be homogeneously applied to the keratin fibers without said agents dripping after application. The agents result in a homogeneous lightening and a good hairstyle hold. A method for lightening and temporarily shaping keratin fibers uses such cosmetic agents.
