Explanation:
Detailed explanation-1: -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 cells within the strand of hair aren’t alive anymore. The hair you see on every part of your body contains dead cells.
Detailed explanation-2: -The shaft is the visible part of the hair that sticks out of the skin. The hair root is in the skin and extends down to the deeper layers of the skin. It is surrounded by the hair follicle (a sheath of skin and connective tissue), which is also connected to a sebaceous gland.
