Almost your entire body is covered with hair, though much of it is so fine that it is barely visible. The hair grows from some five million follicles, of which about 100,000 are in the scalp. By the time each hair emerges from within a follicle, it is already dead and no amount of massage, hair tonic or wonder cure can revive it.

Scalp hair grows on average about 12 to 15 cm (5 to 6 in) a year. It keeps getting longer, even through it is dead, because the older, dead hair cells are pushed out by the new hair growth. Cut the dead hair and it doesn’t hurt, but pull hair form the roots and you may cry out with pain.

Every time you brush or comb your hair, you may remove as many as 100 hairs. Unless the loss is excessive, this is no cause for worry. The hairs come from roots that are in their resting phase.
