Abstract
The invention concerns a hairstyling composition capable of being remodelled for keratin fibers in particular hair, containing in an appropriate cosmetic vehicle at least a polymer selected such that the composition, after being applied on the fibers and dried, provides a hairstyling substance having a glass temperature (Tg) less than +10° C. and a separation profile defined by at least: (a) a maximum separation force Fmax>1 Newton and (b) when said glass temperature Tg is less than −15° C., by a separation energy Es(M/V) of the substance contacted with a glass surface, less than 300 &mgr;J. The invention also concerns an aerosol device containing this composition and a method for treating keratin fibers such as hair, in particular a method for fixing and/or maintaining the hairstyle using said composition.
