Telogen Phase
In the telogen phase, or resting phase, the dermal papilla fully separates from the follicle. This usually lasts five to six weeks. When the resting follicle begins to grow again, the hair shaft falls out.
Anagen phase (first phase of hair growth)
The first phase of hair growth is the anagen phase, the active growth phase, in which the follicle produces new hair cells that are added to the shaft of the hair, thus pushing it toward the surface of the skin and out. This phase can last between two to six years.
Catagen phase
In the catagen phase, the transition phase, the hair converts to a club hair as the part of the hair follicle in contact with the lower portion of the hair becomes attached to the hair shaft. This process cuts the hair off from its blood supply and from the cells that produce new hair. This might take one to three weeks.
