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 vapor form in contact with said hair, without complete drying of the hair during microwave exposure, the solvent in vapor form being entirely generated by the evaporation of a compound which is present, before emission of the microwaves, in contact with the treated hair.

Hair treatment method

Keratin fibers, in particular human hair and especially artificially dyed human hair, are protected against the action of atmospheric agents and especially against the action of light by application to the keratin fibers/hair of a composition containing at least one protective agent having a log P of less than or equal to 6, followed by the application to the fibers hair of a heating iron at a temperature of greater than or equal to 60&#xb0; C.

Photoprotective treatment of keratin fibers by application of heat

The invention relates to a process for dyeing keratin fibers, in which said fibers are treated: &#x25aa; with a composition (A) comprising i) one or more indole or indoline compounds; ii) one or more metal salts; iii) hydrogen peroxide or one or more systems that generate hydrogen peroxide; and then &#x25aa; with a composition (B) comprising iv) one or more basifying agents. The invention also relates to a hair dyeing process for obtaining better colorations, which are more uniform, chromatic and remanent and which do not impair the cosmetic properties of keratin fibers.

Hair dyeing process using a composition comprising at least one indole or indoline compound, a metal salt, hydrogen peroxide and a basifying agent

Disclosed are methods and kits for coloring the hair involving a color base composition comprising at least one primary dye intermediate, and a developer composition comprising an oxidizing agent chosen from persulfates, perborates, percarbonates, and mixtures thereof. Preferably, the color base composition and developer composition are substantially free of an oxidation catalyst.

Methods and kits for permanently coloring hair

Disclosed herein is a dyeing composition comprising a particular disulphide dye and a method of dyeing human keratin fibers, such as hair, using this composition. This composition makes it possible to obtain particularly fast chromatic colorations.
