The present invention provides a hairstyling cosmetic that applies easily; fits smoothly to hair; thickens thus has a superior hairstyling capacity immediately after application; and has suitable setting capacity, re-hairstyling capacity, and non-stickiness because upon completion of hairstyling, entire solvent volatilizes and a hairstyling component precipitates. The hairstyling cosmetic of the present invention is characterized by comprising: (a) one or more block-type alkylene oxide derivative(s) selected from formulae (I), (II), and (III), which is solid at room temperature (25° C.) and insoluble in water but soluble in lower alcohols to become transparent; and (b) a solvent containing water and a lower alcohol, wherein the component (a) dissolves in component (b), and as the lower alcohol preferentially volatilizes after application, component (a) is admixed with the solvent with a changed composition, and then substantially entire solvent volatilizes: R1O-[(AO)p(EO)q(AO)r]—R2  (I) R1O-[(EO)p(AO)q(EO)r]—R2  (II) R1O-[(EO)p(AO)qR3(AO)s(EO)r]—R2  (III) wherein AO is an oxyalkylene group having 3 to 4 carbon atoms, EO is an oxyethylene group, p, q, r, and s are the average addition mole numbers, 1≦p+r≦90, and 1≦q+s≦90, the percentage of the oxyethylene groups with respect to the sum of the oxyalkylene groups having 3 to 4 carbon atoms and the oxyethylene groups is 20 to 80 mass %; each of R1 and R2 is a hydrocarbon group having 1 to 4 carbon atoms or a hydrogen atom and they can be either the same or different; and R3 is a linear or branched hydrocarbon group having 1 to 36 carbon atoms.
