Researchers develop 'green' way to extract hair compounds that could be used for bandages, sunscreens

Hair styling can be a potent form of self-expression, whether it features dramatic updos, intricate braids or crazy colors. Beyond being a reflection of our personality, these strands contain compounds that could one day appear in bandages, sunscreens or other products. Researchers reporting in ACS Omega have now designed a simple, green process to extract both keratin and melanin from human hair for these possible applications without harsh chemicals or excessive waste.
