Abstract
A hair styling method, including the steps of:
- applying a hair cosmetic composition containing a component (A) to the hair:
- Component (A): an organopolysiloxane wherein at least two silicon atoms in organopolysiloxane segments which constitute the main chain of the organopolysiloxane (a) are bound to poly(N-acylalkyleneimine) segments (b) consisting of repeating units represented by the following general formula (1):
via respective alkylene groups each containing a hetero atom,
- wherein the number-average molecular weight of the poly(N-acylalkyleneimine) segments is from 1,200 to 5,500,
- wherein the mass ratio of the component (a) to the component (b) [i.e., a/b] is from 35/65 to 60/40,
- wherein the weight-average molecular weights of the organopolysiloxane segments between adjacent two poly(N-acylalkyleneimine) segments (b) are from 1,300 to 5,500, and wherein the weight-average molecular weight of the organopolysiloxane segments (a) is from 7,000 to 100,000;
- forming the hair style at a hair temperature of 50° C. or higher;
- and subsequently cooling the hair temperature to lower than 50° C. to fix the formed hair style.
