Abstract
A hydrogel that comprises denatured human hair biomolecules intermolecularly crosslinked with disulfide bonds to form a hydrogel. The hydrogel may be prepared by reduction and denaturation of hair to provide keratins and other hair biomolecules that are crosslinked by the disulfide bonds to provide a firm, flexible, and useful biomaterial.
