The Hair

The roots of the hair are each supplied with a blood vessel of its own and with proper nerves, though the latter do uot extend into the hair itself. On the health of the roots of the hair the whole growth depends. Ou either side of the root and a little above it are two email glands, which secrete an oily substance that gives gloss to the hair, and the glands serve to protect the roots of the hair from becoming clogged with dust. Each separate hair is a hollow tube and throngh its length is conveyed the f ood essential to health and wowth.
