What is keratin?
Keratin is a strong, fibre-based protein material.
Keratin is found on amphibians, birds, mammals, and reptiles.
Keratin is the material in animal beaks, bills, claws, feathers, fingernails, hair, hooves, horns, scales, shells, talons, toenails, and wool. It is also in the outer layer of human skin.
Keratin comes from the Greek word “keras” or “ceros” which means horn. Rhinoceros means “nose with a horn” for example.
