Abstract

Disclosed are shampoo compositions that provide a superior combination of anti-dandruff efficacy and conditioning, and a method of cleansing and conditioning the hair comprising applying to the hair and scalp an effective amount of said compositions. The anti-dandruff and conditioning shampoos comprise: (A) from about 5% to about 50%, by weight of the composition, of an anionic surfactant; (B) from about 0.01% to about 10%, by weight of the composition, of a non-volatile conditioning agent; (C) from about 0.1% to about 4%, by weight of the composition, of an anti-dandruff particulate; (D) from about 0.02% to about 5%, by weight of the composition, of at least one cationic polymer; (E) from 0.005% to about 1.5%, by weight of the composition, of a polyalkylene glycol corresponding to the formula: H(OCH₂—CHR)_n—OH, (i) wherein R is selected from the group consisting of hydrogen, methyl and mixtures thereof, (ii) wherein n is an integer having an average value from about 1,500 to about 120,000; and (F) water.
