ABSTRACT:
A two part aqueous composition for coloring and providing durable conditioning to human hair which forms a gel on mixing of an alkaline aqueous lotion first part having a pH of from about 7 to about 11 containing from about 0.005% by weight to about 5% by weight of at least one primary intermediate and at least one coupler for the formation of oxidation dyes, from about 0.1% to about 5% of a cationic polymer, from about 0.5% to about 15% by weight of an anionic or amphoteric surfactant or mixture thereof and at least 70% by weight water, and an aqueous developer second part having a pH of from about 2 to about 6 containing from about 0.5% by weight to about 40% by weight of a peroxide oxidizer and from about 0.1% by weight to about 20% by weight of an anionic polymer, the anionic polymer being characterized in that it is insoluble in the developer and dissolves in the gel which forms when the lotion and developer are mixed.
