A normal human being has approximately 1 million hair follicles on his body, of which 1 lac hairs are on the sealp. A hair normally grows at the rate of approximately 1 cm per month, but each hair grows in cycles, cach cycle being constituted by the growth phase (anagen), the transition phase (catagen) and the resting phase (telogen) The catagen phase in a hair cycle usually lasts 3 weeks while the telogen phase lasts 3 months.
The duration of the anagen phase in different hair follicles however, varies depending upon the site of the body.
In the scalp hair the duration of the anagen phase can be as long as 10 years After completing the anagen phase, each hair follicle enters into the catagen phase which is followed by the telogen phase. The old hair however, falls off only after the ompletion of the telogen phase and when the new hair has already started growing in its place.
