Hair Growth
STOP THE LOSS
There are about 100,000 hair follicles on the human scalp. On average hair grows at a rate of half an inch per month for up to eight years (anagen phase). After this period growth is halted and the hair follicle enters into a short transitional phase for up to two weeks (catagen), before entering into a dormant period for one to four months (telogen phase). Thereafter the above cycle starts over again with new hair growth. Every hair follicle on the scalp goes through this cycle independently and at any given time about 85% of all hair follicles are usually in the anagen phase. It is normal for humans to lose about 50 100 hairs per day. The exact rate is highly individual. Only if more hair is lost than replaced, visible hair loss can be observed.
