Abstract: 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).

Abstract: A process for treating keratin fibres may include applying a hair treatment composition to the keratin fibres. The composition may comprise at least one of fatty substances, surfactants, polymers with a glass transition temperature (Tg) ranging from about 40° C. to about 150° C., oxidation dye precursors, and direct dyes. The process may also include inserting the keratin fibres into a device comprising two elements that are moveable relative to each other between an open position and a closed position. In the closed position, the two elements may define a substantially leaktight closed space. The process may further include moving the two elements into the closed position to confine the keratin fibres in the closed space, and heating the keratin fibres to a temperature ranging from about 40° C. to about 250° C. while the keratin fibres are confined in the closed space.

Abstract: The present invention relates to a cosmetic hair treatment method comprising at least the steps consisting of: a) applying a mechanical tension to said hair, b) exposing said hair under mechanical tension to microwaves, in the presence of a solvent in vapour form in contact with said hair, without complete drying of the hair during microwave exposure, the solvent in vapour form being entirely generated by the evaporation of a compound which is present, before emission of the microwaves, in contact with the treated hair.
