Abstract
A method of achieving improved hair feel. The method comprises applying to hair a composition comprising: (a) a specific cationic guar polymer; (b) a specific cationic copolymer; (c) an anti-dandruff active; (d) a cosmetically acceptable carrier; (e) a surfactant; wherein the weight ratio of (a):(b) is from about 1000:1 to about 3.5:1; and wherein the sum of (a)+(b) is an amount of from about 0.0001% to about 0.7%, by total weight of the composition. The composition forms coacervate particles upon dilution of the composition with water and the coacervate particles have a squeeze flow viscosity of from about 1 cP to about 100 cP. The percentage of coacervate particles with a floc size of greater than about 20 micron is from about 1% to about 60% and the on-scalp deposition of the anti-dandruff active is at least about 1 microgram/cm2.
