The invention provides a hair cosmetic comprising a novel block copolymer capable of sustainably imparting properties such as slipperiness to hair.
The hair cosmetic of the present invention comprises a block copolymer having a hydrophobic segment and a hydrophilic segment, wherein the hydrophobic segment has a monomer unit composed of at least one monomer selected from the following Formula 1 and Formula 2, wherein the hydrophilic segment has a monomer unit composed of a monomer of the following formula 3:
where R1 is hydrogen or a methyl group, R2 is hydrogen or fluorine, m is an integer of 1 to 6, and n is an integer of 5 to 15,
where R1 is hydrogen or a methyl group, R3 and Rare each independently an alkyl group having 1 to 6 carbon atoms, m is an integer of 1 to 6, and p is an integer of 5 to 70,
where R1 is hydrogen or a methyl group, m is an integer of 1 to 6, and R5 are each independently a functional group that hydrolyzes and cross-links.
