An aerosol device comprising a container containing an aerosol composition, comprising, on the one hand, a liquid phase (or fluid) containing at least one fixing material in a suitable solvent and, on the other hand, a propellant, and a means for distributing the aerosol composition, the fixing material having a glass transition temperature (Tg) of greater than or equal to 40° C., the fixing material comprising at least one polymer containing vinyllactam units, and the device being suitable for obtaining a wetting power of greater than or equal to 40 mg/s. The invention also relates to a process for treating keratin fibres, in which a composition comprising a fixing material having a glass transition temperature (Tg) of greater than or equal to 40° C., this fixing material comprising at least one polymer containing vinyllactam units, is applied to the fibres by means of a suitable device in order to obtain a wetting power of greater than or equal to 40 mg/s.
