[Also in Division C5] Hair shampoos for combatting dandruff comprise a detergent and, as active product, at least one of arginine, histidine or lysine, or an inorganic or organic acid salt thereof, or an ester thereof. Salts may be formed with citric, nicotinic or malic acid and esters with aliphatic or aromatic alcohols, e.g. the methyl ester of lysine. The shampoo may have a pH of at least 6 such as 8.5) and contain 0.2 to 5% by weight of the active product. The shampoo may also contain a penetrating agent, surface active agent, perfume, dye, gloss-producing agent and known antidandruff agents (such as bactericidal agent, e.g. cetrimonium bromide).
