<p>A hair cosmetic is disclosed, which comprises the following components (a) and (b): (a) a poly(N-acylalkyleneimine)-modified silicone having a poly(N-acylalkyleneimine) segment and an organopolysiloxane segment at a weight ratio of said poly(N-acylalkyleneimine) segment to said organopolysiloxane segment of from 1/20 to 20/1, and having a molecular weight of from 500 to 500,000, wherein said poly(N-acylalkyleneimine) segment comprises a repeating unit represented by the following formula (I): <CHEM> wherein R1 represents a hydrogen atom, an alkyl group having 1 to 22 carbon atoms, a cycloalkyl group having 3 to 22 carbon atoms, an aralkyl group having 7 to 22 carbon atoms or an aryl group having 6 to 22 carbon atoms; and n is 2 or 3; and (b) a film-forming polymer. The hair cosmetic of the present invention is effective in imparting a natural gloss, smoothness, flexibility, smooth-combing properties and water repellency to the hair without deteriorating the hair setting retention function. e</p> |
