The invention relates to a cosmetic process for treating keratin fibers, preferably the hair, comprising at least the steps consisting in: a) applying to said keratin fibers a composition containing at least one substance chosen from fatty substances, non-silicone polymers and surfactants, b) applying a mechanical tension to said keratin fibers, and c) exposing said keratin fibers under mechanical tension to microwaves, at a pressure ranging from 50,000 to 250,000 Pa, in the presence of at least one solvent in vapor form on contact with the keratin fibers and without there being complete drying of the keratin fibers throughout the entire exposure to the microwaves, the solvent(s) in vapor form being entirely generated by evaporating at least one compound present, before emission of the microwaves, on contact with the keratin fibers, step a) taking place prior to step c).

This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. This is achieved through a judicious combination of an organic UV filter, a zinc compound and selective anti-dandruff agent. The composition comprises 0.01 to 3% by weight zinc pyrithione, an organic UV filter and 0.1 to 5% by weight additional zinc compound. The weight ratio of zinc compound to zinc pyrithione is over 3:1.

An agent for dyeing keratinous material is provided. The agent includes at least one amino-functionalized silicone polymer and at least one color-imparting compound. Further, the agent includes at least one preservative and at least one non-ionic surfactant from the group of addition products of ethylene oxide and C.sub.8-C.sub.24 fatty alcohols.

A process for dyeing keratinous material is provided. The process includes (1) applying a coloring agent (a) to the keratinous material. The coloring agent (a) includes (a1) at least one amino-functionalized silicone polymer and (a2) at least one colorant compound. The method further includes (2) allowing the coloring agent (a) to act on the keratinous material for a period of 15 seconds to 10 minutes, and (3) rinsing out the dye (a) under running water for a period of 15 seconds to 10 minutes. In the process, no further cosmetic agent other than the coloring agent (a) is used.

It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one amino-functionalized silicone polymer, and (a2) at least pigment,
the weight ratio of all the pigments (a2) contained in the composition to all the amino-functionalized silicone polymers (a1) contained in the composition, i.e., the weight ratio (a2)/(a1), being not more than 0.95.

A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.
