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.

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.

Methods for reaction electrospinning are provided to form collagen fibers. The method can include: acidifying a collagen in an acidic solvent to form an acidic collagen solution; electrospinning the acidic collagen solution within an alkaline atmosphere (e.g., including ammonia vapor) to form collagen fibers; and collecting the collagen fibers within a salt bath (e.g., including ammonium sulfate). The acidic solvent can include water and an alcohol, and can have a pH of about 2 to about 4 (e.g., including a strong acid, such as HCl). An albumin rubber is also provided, which can include albumin crosslinked with glutaraldehyde.
