Provision of hair cosmetics that can be used. A hair cosmetic comprising a tertiary amine represented by formula (1), a pyrrolidone carboxylic acid, and a higher alcohol. (In the formula (1), R 5 is an alkyl group having 8 to 30 carbon atoms, A is an amide group or ether group, m is 0 or 1, and when A is an amide group, R 6 is an alkylene group having 2 to 4 carbon atoms. Or a hydroxyalkylene group, when A is an ether group, R 6 is an alkylene group having 2 to 4 carbon atoms, and R 7 is a linear or branched chain having 8 to 30 carbon atoms which may be interrupted by an amide group or an ether group. An alkyl group or an alkenyl group, or a linear or branched alkyl group or hydroxyalkyl group having 1 to 3 carbon atoms, and R 8 is a linear or branched alkyl group or hydroxyalkyl group having 1 to 3 carbon atoms.)
