The facts about hair growth.

1. It is normal to lose 50-100 hairs from the head each day.

2. Each hair on the head grows for about 3-5 years before being shed.

3. Scalp hair grows at a rate of about 1 cm (just under 1/2 an inch) a month.

4. We each have about 100,000 hairs on the scalp.

5. Hair growth is not a continuous process - it has several stages:

ANAGEN PHASE. The first phase is the growing stage. Hair grows at about 1 cm each month, and this phase lasts for anything between 2 and 5 years.

CATAGEN PHASE. As this phase begins the bulb detaches from the blood supply and the hair shaft is pushed up.

THE TELOGEN PHASE. This is followed by a resting stage, during which there is no growth. This phase lasts about 5 months.

At the end of the resting phase, the hair is shed, and the follicle starts to grow a new one.

At any moment, about 90% of the hair follicles of the scalp are growing hairs in the first phase; only about 10% are in the resting phase.

If a follicle is destroyed for any reason, no new hair will grow from it.
