Provided is method of strengthening keratinous fibers that includes contacting the fibers with a composition that includes a poly(vinylamine-vinylformamide) copolymer and a carrier, wherein the treated fibers exhibit an improvement in strength. Also provided are methods for improving strength of fibers that have been damaged, e.g., as a result of having been subjected to chemical and/or thermal treatment processes that diminish fiber strength, by contacting the fibers with the composition.
L'invention porte sur un procédé de renforcement de fibres kératiniques qui comprend la mise en contact des fibres avec une composition qui comprend un copolymère poly(vinylamine-vinylformamide) et un support, les fibres traitées présentant une amélioration de la résistance. L'invention porte également sur des procédés d'amélioration de la résistance de fibres qui ont été endommagées, par exemple, pour avoir été soumises à des procédés de traitement chimique et/ou thermique qui diminuent la résistance des fibres. Selon les procédés de linvention, les fibres sont mises en contact avec la composition.
