• The Antagen Growth Phase  last anywhere from two to eight years in women depending on the individual and during this phase the hair grows approximately 1/2 inch per month while the potential length of grow is determined by the length. Long before the hair breaks the surface of the skin activity in the hair follicle marks the beginning of the Anagen Phase where the dermal papilla forms and the follicle grows 3x's it's resting length.
• The Catagen Growth Phase is set off by a signal from your body that is sent out when the Anagen Phase ends this will begin the cycle of the Catagen Phase. This phase is also known as the transitional phase because it allows the hair follicle to renew itself in a way and during this time (which can last for as long as two weeks), the hair follicle shrinks from disintegration and the papilla detaches and (rests) cutting the hair strand off from it's nourishing blood supply so that it can set the stage for the formation of a new follicle.
• The Telogen Growth Phase is when ten to fifteen percent of the hairs on an individual's head is in this phase of growing at any given time and this phase can last up to six weeks but the hair and follicle remains dormant anywhere from one to four months. This stage of phase causes the normal hair loss known as shedding when the preceding hair strand is pushed up and out by the new growing strand. At the end of this phase of growth hair cycle pattern the hair follicle re-enters into the growth phase of the cycle again (Anagen Phase) where the derma papilla and the tubular base of the follicle join forces again to create the cycle of the beginning of a new hair life that is to begin to form as the Telogen Growth Phase is complete.

The relative duration of these phases varies with the individuals age, nutritional status, hormonal factors and other physiologic and pathologic factors of each individual.
