Claims10
A process for dyeing hair comprising applying to said hair in an amount sufficient to color said hair a hair dye formulation comprising a mixture of an effective amount of an oxidation hair dye composition containing at least one hair dye or dye precursor, and a hair dye carrier, an effective amount of an oxidizing agent and an effective amount of at least one cationic polymer, permitting said hair dye formulation to remain in contact with said hair for a time of about 5-40 minutes, rinsing said hair with water, applying to said rinsed hair an effective amount of a shampoo formulation comprising an effective amount of at least one anionic detergent and rinsing said hair with water.
A composition for dyeing hair comprising a combination of two formulations, one to be applied to the hair immediately after the other, the first to be applied formulation being an effective amount of a hair dye formulation comprising a mixture of an oxidation hair dye composition containing an effective amount of at least one hair dye or dye precursor and a hair dye carrier, an effective amount of an oxidizing agent and at least one cationic polymer, said cationic polymer being present in an amount between 0.5 and 10 percent by weight of said hair dye formulation, and the last to be applied formulation being an effective amount of a shampoo formulation comprising an anionic detergent present in an amount ranging from 4--30 percent by weight of said shampoo formulation.
