One subject of the invention is a method for making up eyelashes, consisting in: a) coating the eyelashes with a deposit of at least one composition comprising, in a physiologically acceptable medium, at least one compound enabling the composition to attain, in the at least partially dry state, a modulus of rigidity Gp greater than or equal to 1 GPa, b) in the presence of a stimulus to which said compound is sensitive, placing a shaping tool in contact with the thus coated eyelashes so as to modify the curvature of the eyelashes, said contact being maintained until the modulus of rigidity Gp of the composition is at least equal to 1 GPa, the stimulus being chosen so that the modulus of rigidity of at least 1 GPa is obtained in a time t that is less than the time t0 that would be needed to obtain it by leaving the deposit to dry at room temperature.
