Abstract:
A hair conditioning composition which when applied to color-treated hair prior to perming with formulations based on thioglycolate or sulfite minimizes the reduction in tensile strength of the hair comprising about 0. 1 to about 4. 0 weight-percent of a water-dispersible dialkyl (C. sub. 12-18) dimethyl ammonium halide; about 0. 1 to about 2. 5 weight-percent of alkyl (C. sub. 12-18) dimethyl benzyl ammonium halide; about 0. 1 to about 2. 0 weight-percent of a homopolymer of diallyl dialkyl ammonium halide; optionally a thickener, a moisturizer, an emulsifier, a protein conditioner, a preservative, a colorant, and/or a perfume; and the remainder to 100 weight-percent water; and a method of conditioning color-treated hair therewith.
