Abstract

Abstract A preserved composition suitable for topical application to mammalian skin or hair for inducing, maintaining or increasing hair growth comprises, as a hair growth promoter, a hexosaccharic acid and/or a salt or ester thereof, in an amount sufficient to increase hair growth in the rat, when the composition is applied topically thereto over a period of no more than 3 months, by at least 10% more than that obtainable using a control composition from which the promoter has been omitted, in accordance with the Rat Hair Growth Test.
