The present invention relates to a composition for the simultaneous bleaching and dyeing of keratin fibres, comprising at least one chemical oxidizing agent, at least one (bi)carbonate, at least one silicate and at least one oxidation dye, and also to a process for the simultaneous bleaching and dyeing of keratin fibres using this composition.

The present disclosure relates to hair coloring base compositions and ready-to-use hair coloring compositions comprising 2-methoxymethyl-P-phenylenediamine, an oxidative dye precursor. The hair coloring base composition is mixed with a developer composition to form a ready-to-use hair coloring composition having a lower than typical pH, 7. These compositions are effective for coloring hair, especially beard hair. The color imparted to the hair is long-lasting (tenacious) and skin sensitivity due to the coloring process is minimized or prevented. Methods for making the composition and methods for coloring hair, especially beard hair, are also disclosed.

Composition comprising the combination of two particular oxidation dye precursors and an alkyl(poly)glycoside The invention relates to a composition comprising at least one oxidation base chosen from 2-(methoxymethyl)para-phenylenediamine of formula (I), one of its addition salts, its solvates and/or the solvates of its salts, at least one oxidation coupler chosen from hydroxyethyl-3,4-methylenedioxyaniline of formula (II), its addition salts, its solvates and/or the solvates of its salts, and at least one alkyl(poly)glycoside, e.g. coco-glucoside. The invention also relates to a process for dyeing keratin fibres, preferably the hair, comprising the application of the composition to said keratin fibres.
