Zusammenfassung:Composition for the simultaneous (dis)coloration of keratinous fiber comprises a dye comprising an anionic or non-ionic dye preferably 7-(6'-methylphenylazo)-1-acetamido- 3,6-disulfo-8-hydroxy- naphthalene, o-nitro-anilines substituted by meta directing group like amino, quinoline or its derivatives or salts; an associative polymer; a peroxide salt; and an alkaline agent. Independent claims are also included for: (1) a process of discoloring and coloring simultaneously of the keratinous fibers comprising applying the anhydrous composition on the fibers in the presence of an aqueous composition optionally comprising hydrogen peroxide; and (2) a device with several compartments comprising the compositions.
