The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dyes chosen from synthetic direct dyes and dyes of natural origin, b) one or more titanium salts and b1) optionally one or more particular carboxylic acids, c) one or more cellulose-based polysaccharides, d) optionally one or more organic compounds that are liquid at 25&#xb0; C., with a Hansen solubility parameter value &#x3b4;H&#x3c;16 (MPa)at 25&#xb0; C., e) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

Hair dyeing process using at least one direct and/or natural dye, a titanium salt, a cellulose-based polysaccharide and optionally a particular organic solvent

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dye(s), b) one or more titanium salts and b1) optionally at least one carboxylic acid, and c) one or more anionic thickening polymers derived from the polymerization of at least one monomer bearing an organic monoacid function, and d) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

Hair dyeing process using at least one dye, a titanium salt and an anionic thickening polymer

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dye(s), b) one or more titanium salts and optionally b1) at least one carboxylic acid, and c) one or more non-cellulosic-based polysaccharides, and d) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

Hair dyeing process using at least one dye, an organic titanium salt, and a non-cellulosic-based polysaccharide

The present invention relates to a method for coloring keratin fibers, comprising: &#x2014;a first step of applying to the fibers a dyeing composition (a) comprising one or more dyes chosen from chromene dyes and chroman dyes, and one or more liquid organic compounds having a Hansen so lubility parameter &#x3b4;H of less than or equal to 16 Mpa, then &#x2014;a second step of applying to the fibers an oxidizing composition (b) comprising one or more oxidizing agents and one or more alkaline agents, one or more metal salts and/or metal oxides being present in at least one of the compositions (a) and (b), and/or being applied during an additional step by means of a composition (c). The invention likewise relates to a kit suitable for implementing this method.

Hair colouring method employing a chromene or chroman dye, a particular organic compound, an oxidizing agent, an alkaline agent and a metal salt

The present invention relates to a process for dyeing hair using at least one water-insoluble silicate, at least one compound of formula (I), in which Y represents a C1-C4 hydroxyalkyl group or a C1-C4 hydroxyalkyloxy radical, n denotes an integer ranging from 0 to 5, X, which may be identical or different, represents a C1-C4 alkyl radical or a halogen; and at least one hydroxylated aliphatic solvent comprising therein from 2 to 6 carbon atoms.
