  The present invention relates to a process for dyeing and relaxing curls of keratin fibres, such as the hair, which comprises the application to the fibres of one or more acidic compositions comprising reducing agents and of one or more compositions comprising hair-dyeing agents, and a step of heat treatment of the fibres by means of a heating tool. A subject of the invention is also the use of the composition(s) comprising reducing agents and of the composition(s) comprising hair-dyeing agents in a process for dyeing and relaxing curls of keratin fibres. Finally, a subject of the invention is a multi-compartment device or "kit" suitable for carrying out such a process.

  The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising at least one step of applying a composition comprising at least two organosilanes, that are different from one another, and at least one step of applying a composition comprising anionic direct dyes and surfactants. The present invention also relates to the use, as pretreatment, of at least two organosilanes, that are different from one another, for improving the dyeing properties of a composition comprising anionic direct dyes.

  Cosmetic composition for direct dyeing comprising an aqueous phase and a fatty phase that are visually distinct from each other The present invention relates to a cosmetic composition for the direct dyeing of keratin fibres, comprising: -an aqueous phase (A) comprising at least 0.1% by weight, relative to the total weight of the composition, of one or more direct dyes, one or more aqueous-phase thickeners, one or more organic solvents and water, -at least 10% by weight, relative to the total weight of the composition, of a fatty phase (B) comprising one or more oils and one or more fatty-phase thickeners. The invention also relates to a process for preparing this composition. Finally, the invention relates to a process for the direct dyeing of keratin fibres, comprising a step of applying the above composition to the keratin fibres.
