Abstract:
Disclosed herein are compositions for dyeing keratin fibers, for example human keratin fibers such as the hair, comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2 -a]pyrazol-1-one or an addition salt thereof, at least one oxidation base, at least one coupler, at least one surfactant chosen from oxyalkylenated or glycerolated fatty alcohols, anionic surfactants of sulfate or sulfonate type and amphoteric surfactants of betaine type, and at least one oxidizing agent, the pH of the composition ranging from 5. 5 to 7. 5. The compositions disclosed herein make it possible to obtain coloration on keratin fibers with tints in red, coppery or mahogany tones that are sufficiently visible on natural or dyed hair and/or uniform from the roots to the ends.
