Method for strengthening keratinous fibers
First Claim
1. A method of strengthening keratinous fibers, the method comprising contacting the fibers with a strengthening-effective amount of a composition consisting of a poly(vinylamine-vinylformamide) copolymer and an aqueous carrier wherein the poly(vinylamine-vinylformamide) copolymer is selected from the group consisting of a high molecular weight poly(vinylamine-vinylformamide) copolymer and a low molecular weight poly(vinylamine-vinylformamide) copolymer.

Abstract
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.
