Human hair is made of the same stuff that horns, fingernails, cat and dog claws, cow and horse hooves, and bird feathers are made of a protein called keratin. And it grows out of a tiny opening in the skin called a follicle. One kind of keratin is made of long protein chains, and the coiled chains wind around each other to resemble a shape much like a twisted telephone cord.
All parts of the body have hair except the lips, palms, and soles of the feet. Adults have about five million hairs growing out of the body. That’s about the same number as a gorilla.
