Abstract:
The invention relates to a composition for dyeing keratin fibres, comprising at least one diamino-N,N-dihydropyrazolone derivative or an addition salt thereof, as oxidation base, and at least one stabilizer chosen from a dithionite, vitamin E and a vitamin E ester. The invention also relates to the dyeing process using such a composition. The composition in accordance with the invention is stable and makes it possible to obtain a strong, chromatic, aesthetic, sparingly selective coloration in varied shades, which shows good resistance to the various attacking factors to which the hair may be subjected, such as shampooing, light, sweat and permanent reshaping.
