Abstract

Abstract A hair dye composition comprising the following three components (A), (B) and (C): (A) one or more cysteine derivatives selected from among a compound represented by the following general formula (I): ##STR1## wherein R 1 represents a hydrogen atom or an acyl or alkyl group carrying one to three carbon atoms, and glutathione, or a salt thereof; (B) an aromatic alcohol and/or a compound represented by the following general formula (II): R.sub.2 -OCH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OH (II) wherein R 2 represents an alkyl group carrying one to five carbon atoms; and (C) a dye.
