PURPOSE: To obtain an acidic composition for hair having a shape holding ability in coating hair with it, capable of applying to the hair without dripping and expressing an excellent hair washing performance owing to viscosity reduction during application by containing an acid dye, an aromatic alcohol, a volatile solvent, a water soluble high molecular compound and an acid. CONSTITUTION: This acidic composition for hair contains (A) an acid dye, (B) an aromatic alcohol (preferably benzyl alcohol, 2-phenylethyl alcohol, cinnamyl alcohol, phenylpropanol, phenoxyethanol,α-methylbenzyl alcohol and dimethylbenzly carbinol) in a quantity to be excess at a room temperature for a nonvolatile water-based part in the composition, (C) a volatile solvent (preferably ethanol) capable of dissolving the aromatic alcohol in the supersaturated part, (D) a water soluble high molecular weight compound capable of being gelled by heat (preferably methyl cellulose, hydroxypropylmethyl cellulose, etc.) and (E) an acid (preferably hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, lactic acid, glycolic acid, succinic acid).
