Abstract: The disclosure relates to a composition for dyeing keratin fibers, in particular human keratin fibers such as hair, comprising one or more oxidation dyes, one or more scleroglucan gums in a total weight content greater than or equal to 0.5% relative to the total weight of the composition, and one or more cationic polymers. The disclosure also relates to a method for dyeing keratin fibers using said composition and to a multi-compartment device suitable for implementing said composition.

Abstract: The disclosure relates to a composition for dyeing keratin fibers, in particular human keratin fibers such as hair, comprising one or more oxidation dyes, one or more scleroglucan gums in a total weight content greater than or equal to 0.5% relative to the total weight of the composition, one or more alkaline agents selected from amino acids, the amino acid(s) being present in a total weight content greater than or equal to 1% relative to the weight of the composition, and preferably one or more additional alkaline agents, preferably selected among the mineral alkaline agents and/or alcanolamines. A method for dyeing keratin fibers using said composition and a multi-compartment device suitable for implementing said composition are also disclosed.
