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.

The present invention relates to a hair treatment method including the following step (i) and step (ii) in this order: Step (i): a step of applying a composition containing the following component (A) on a hair: (A) a compound represented by the following general formula (1) or a salt thereof: ##STR00001## wherein a broken line represents the presence or absence of a π bond; R.sup.1 represents a hydroxy group or an acetoxy group; R.sup.2 represents a hydrogen atom or —COOR (R is a hydrogen atom, a methyl group, or an ethyl group); and R.sup.3 represents a hydrogen atom, an acetyl group, a methyl group, or an ethyl group; and Step (ii): a step of giving a shape to the hair while applying a temperature of 140° C. or higher and 220° C. or lower to the hair.

Disclosed is a method of crosslinking protein fibers, including wool fibers, by (i) providing a crosslinking agent including an oxidized sugar mixture having a plurality of different oxidized sugars of different molecular lengths and having at least two aldehyde groups (e.g., oxidized soy flour sugars); and (ii) infiltrating a plurality of non-crosslinked protein fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked protein fibers to become crosslinked. This method yields a population of crosslinked protein fibers, where the protein molecules of the non-crosslinked protein fibers include amine groups that react with the aldehyde groups of the oxidized sugars to achieve the crosslinking of the protein molecules to yield the crosslinked protein fibers.
