PROBLEM TO BE SOLVED: To provide an aerosol-type cosmetic for scalp, which is prevented from dripping without using any water-soluble thickener, applied by hand without slimness, and gives a sense of smoothness to the scalp.SOLUTION: According to the present invention, an aerosol-type cosmetic for scalp consists of a stock solution containing components (A) to (C) and component (D) carbonic acid gas, and has a mass ratio (D)/(A) of 2.5 to 40: (A) poly (N-acylalkyleneimine)-modified organopolysiloxane； (B) organic acid； and (C) water. Here, the poly (N-acylalkyleneimine)-modified organopolysiloxane has its main chain constituted of an organopolysiloxane segment (a) in which at least two of Si atoms thereof are bonded to a poly (N-acylalkyleneimine) segment (b) comprising repetitive unit (1) via an alkylene group containing a hetero atom. The segment (b) has a molecular weight of 1,600 to 6,500 and a mass ratio (a/b) of 40/60 to 60/40. An organopolysiloxane segment between the adjacent poly (N-acylalkyleneimine) segments (b) has a molecular weight of 1,600 to 7,000, and (a) has a molecular weight of 7,000 to 10,0000.SELECTED DRAWING: None
