Disclosed is a method of crosslinking hair or other keratin fibers by (i) providing a crosslinking agent comprising an oxidized sugar having at least two aldehyde groups; and (ii) infiltrating a plurality of non-crosslinked hair or other keratin fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked hair or other keratin fibers to become crosslinked, thereby yielding a population of crosslinked hair or other keratin fibers. The protein molecules include amine groups that react with the aldehyde groups of the oxidized sugar to yield the crosslinked hair or other keratin fibers. Also disclosed are formulations for crosslinking hair or other keratin fibers and methods of using the formulations to treat human hair to maintain a desired three dimensional structure. This formulation includes a crosslinking agent having a plurality of oxidized sugars having at least two aldehyde groups or mixture thereof.
