Did you know that hair is made from the same material that makes up fingernails, birds’ feathers and reptilian scales? It’s called keratin.Keratin refers not to one particular substance but to a family of tough, fibrous proteins found in the animal kingdom. Keratin is present in hair, horns, hooves, beaks, shells, fingernails, toenails, and claws. All proteins contain carbon (C), hydrogen (H), nitrogen (N), and oxygen (O). One of the proteins found in keratin is cysteine. Cysteine contains the fifth element, sulfur (S).
