Each scalp and beard hair grows two to six years before stopping, attaining a typical maximum length of two to three feet. Then it becomes dormant for about three months, whereupon a new hair starts growing and pushes the old one out of the follicle from behind. That's why even someone who's not balding loses 70 to 100 head hairs a day. By comparison, the growth cycle for other body hair is only a few weeks.
