[Freethinker]

From a National Institute of Health site:

Hair Comes From Where?
Whether hair is growing out of your head, arm, or ankle, it all rises out of the skin in the same way. Each hair begins at its hair root, a place beneath the skin where <u>cells</u> band together to form keratin. The root is inside a follicle (say: foll-ick-ul), which is like a small tube in the skin. As the hair begins to grow, it pushes up from the root and out of the follicle, through the skin where it can be seen. Tiny blood vessels at the base of every follicle feed the hair root to keep it growing. But once the hair is at the skin's surface, the <u>cells</u> are no longer alive - the hair you see on every part of your body is <u>dead</u>.
