, guar concentration in aqueous solution, and treatment time on bleached European hair have been studied. A mechanical testing method has been successfully applied to determine the efficacy of cationic guars to improve the ease of combing. The results were confirmed in a shampoo formulation on both virgin and bleached hair.
