A polymer suitable for use in hair cosmetics is provided. A structural unit derived from a hydrophobic monovinyl monomer is 10% by weight or more, a structural unit derived from a hydrophilic monovinyl monomer is 30% by weight or more, and a structural unit derived from a polysiloxane group-containing vinyl monomer is contained. A polysiloxane group containing 1% by weight or more, wherein the difference between the melting point of the polymer and the melting point of the polymer composed of only the structural unit derived from the hydrophobic monovinyl monomer is 10 ° C. or less. Containing polymer. Hair cosmetics containing this polymer have a good feel at the time of use, and their effects are maintained. [Selection diagram] None |
