Abstract

A film coating for keratin fibers is described. The film coating is produced by applying to the keratin fibers a pretreatment composition and a film forming composition and curing the compositions to produce the film coating. The coating may be clear and function as a styling, conditioning and holding. The coating alternatively may contain pigment particles and provide a color coating.
