PURPOSE:To provide an inexpensive stable hair cosmetic for preventing dandruff and containing a selenoamino acid containing selenium atom in the structural formula and/or its salt. CONSTITUTION:The objective hair cosmetic for dandruff prevention contains 0.001-10 wt% (preferably 0.02-5%) selenoamino acid and/or its salt. The selemoamino acid is preferably a selenium compound of a sulfur-containing alpha-amino acid such as selenomethionine, selenocystine, selenocysteine, etc., and its salt is preferably hydrochloride. Since selenoamino acid and its salt are soluble in water, it can be added easily to a cosmetic at a required ratio and is used in the form of hair tonic, milky lotion for scalp, hair cream, hair shampoo, hair rinse, etc. |
