A method for semi-permanently conditioning hair by applying thereto a composition comprising an aqueous oil-in-water emulsion of a mixture of (1) a hydroxy-terminated dimethyl polysiloxane having the general formula where n not less than 500 and (2) a methyl hydrogen polysiloxane having the general formula where n is from about 185-235 and where R is selected from the group consisting of H or CH3, said composition being at an acid pH and wherein the ratio of polysiloxane (1) to polysiloxane (2) is about 100:1 with the total concentration of said polysiloxanes being from about 0.5% to about 10% by weight of said composition, said polysiloxanes in said composition prior to application to said hair being in an unreacted state, said hair being dried after application of said composition resulting in cross-linking of said polysiloxanes on the hair. |
