Hair growth is controlled by a unique repetitive cycle comprised of anagen, catagen and telogen phases (Stenn and Paus, 2001).
This is the hair cycle and it has 3 stages: Anagen, is the active growth period and its length varies from one person to another, lasting about 1,000 days or more; Catagen is the resting or intermediate period, lasting about 10 days; Telogen is the shedding period, lasting about 100 days.
In catagen, the hair follicle stops producing the fiber and regresses, shrinking dramatically.
