Hair keratins are a structural protein found in hair and fingernails and are often referred to as ‘‘hard’’ keratins.  These hard keratins can be used to create gels, films, coatings, creams, and fibers and are used for multiple medical applications such as wound healing, bone regeneration and nerve repair in humans.  It’s growing in popularity to use as more research on its efficacy continue to be produced and more ways of using its unique properties are discovered for both human medical and beauty products.

Keratin offers biocompatibility, which means that it is compatible with living tissue and won’t produce a toxic or otherwise adverse response when used on people or animals. It is also a biodegradable substance and will naturally break down.
