[QUOTE="Nelson Vergel, post: 255304, member: 3"] The life cycle of a hair follicle consists of three phases: anagen, catagen, and telogen. Anagen phase (growth phase): This is the active growth phase of hair follicles. The cells in the hair bulb rapidly divide to produce new hair growth. This phase can last between 2 to 7 years, with hair growing about 1 cm every 28 days. About 85-90% of the hairs on one's head are in the anagen phase at any given time. Catagen phase (transition phase): After the anagen phase, the hair enters the catagen phase, a transitional phase that lasts about 2-3 weeks. During this period, the hair stops growing and detaches itself from the blood supply and is then named a club hair. About 1-2% of hairs are in this phase at any given time. Telogen phase (resting phase): The hair follicle is completely at rest during this phase and the club hair is completely formed. If the old hair has not already been shed, the new hair pushes the old one out and the growth cycle starts all over again. This phase lasts for about 3 months and about 10-15% of hairs are in this phase at any given time. Testing hair growth products often involves measuring the impact of the product on these three phases. A product might be aimed at prolonging the anagen phase, reducing the duration of the telogen phase, or preventing hair follicles from entering the catagen phase prematurely. [/QUOTE]
