Abstract
A keratinous wound healing material, preferably derived from the hair of the patient or a compatible donor. Keratin powder can be derived from hair using processing steps including cleaning, suspending in a liquid carrier, homogenizing and removing the liquid. The keratinous material may be applied to the wound in powder form. The keratin can also be applied in sheet form. The keratinous material can be bound with polymeric binder and formed into a sheet by pouring the polymer/binder solution into a mold and flashing off the solvent.
