Abstract

It is an object of the present invention to provide a hair cosmetic achieving a hair-setting property without causing flaking and further having an excellent hair-rearranging property and non-stickiness. The hair cosmetic of the present invention includes the following components (A) to (D):

• • (A) a (meth)acrylic silicone-based graft copolymer;
  • (B) at least one film-forming polymer selected from nonionic, amphoteric, and cationic polymers;
  • (C) a monohydric lower alcohol; and
  • (D) at least one selected from polyalkylene glycols and sugar alcohols, wherein
  • the component (A) and the component (B) preferably have a content ratio (A):(B) within a mass ratio range of 1:10 to 2:1; and the hair cosmetic preferably has a viscosity at 25° C. of 1000 mPa·s or less.
