Abstract:
The present invention is drawn to an agent and process for altering the color of keratin fibers wherein the agent comprises: (A) a color base composition, containing from about 50% to about 80% by weight of a fatty substance comprising a fatty substance having a viscosity greater than about 50 mm2/s at 40° C.; and optionally, an additional fatty substance; a rheology modifying polymer; and an alkalizing agent; a short alkyl chain hydroxy compound chosen from monoalcohols and polyols; a direct dye; optionally an oxidative dye precursor; and (B) optionally, an oxidizing composition comprising an oxidizing agent.
