Abstract

Claims35
A method for improving color retention in artificially-colored hair comprising applying a treatment composition to shampooed, rinsed, wet hair that has been color-treated previously, the treatment composition comprising:
- (a) a hydrophobic particulate material having a median particle size between about 10 nm and about 20 μm, said hydrophobic particulate material comprising from about 0.1% to about 2.0% by weight of said composition;
- (b) a silicone-based hydrophobic film former comprising from about 0.5% to about 20% by weight of said composition;
- and
- (c) a volatile hydrocarbon or silicone fluid having a vapor pressure above about 0.01 mmHg at 20° C.;
- wherein the aggregate weight percentage of all non-volatile water-soluble or water-dispersible organic constituents in said composition is less than 5%, based on the entire weight of the composition;
- and
- wherein the loss of color from said hair is reduced or prevented following at least one shampooing as compared to otherwise identical hair that has not been treated by said treatment composition;
- and
- wherein said composition is anhydrous.
