Abstract:
1. A hair styling method, comprising: (A) increasing the number of intersections of hair fibers to enhance the volume of hair, and (B) applying an aerosol hair cosmetic composition capable of forming a film having a film strength, as measured by a film strength evaluation method, of 800 gf/cm (C) at least one copolymer selected from the group consisting of (C1) and (C2): (C1) copolymers each composed of: (a) from 30 to 80 mass % of a (meth)acrylamide monomer represented by formula (1): wherein R (b) from 2 to 50 mass % of a (meth)acrylamide monomer represented by formula (2): wherein R (c) from 0 to 30 mass % of a (meth)acrylic acid ester monomer or a (meth)acrylamide monomer represented by formula (3): wherein R (d) from 0 to 40 mass % of a (meth)acrylic acid ester monomer represented by formula (4): wherein R (C2) copolymers each composed of: (a) from 30 to 80 mass % of a (meth)acrylamide monomer represented by formula (5): wherein R (b) from 5 to 45 mass % of a (meth)acrylic acid ester monomer represented by formula (6): wherein R (c) from 2 to 30 mass % of a (meth)acrylic acid ester monomer or a (meth)acrylamide monomer represented by formula (7): wherein R (d) from 0 to 30 mass % of a (meth)acrylic acid ester monomer represented by formula (8): wherein R (D) an anionic film-forming polymer.
