about 85 to 90 percent of your scalp hair is in the anagen or growing phase. Less than 1 percent is in the catagen phase. And, the remaining 14 percent of the scalp hair is in the telogen or resting phase.

Certain factors can rush the growing hair into the telogen phase prematurely, resulting in noticeably thin-looking hair and low hair density. Following the telogen phase, it takes about 3 weeks for the follicle to produce a new anagen hair.

Normal vs. Excessive Hair Shedding

*  Some loss or shedding of hair every day is normal
*  The average person has 150,000 to 200,000 hairs on their scalp
*  Blondes generally have the most number of hairs, followed by brunettes and then redheads

Conventional wisdom has indicated that the loss of 100 to 125 hairs a day is normal. However, recent research has shown that when cleansing daily, a loss of more than 50 hairs per day may be excessive for someone who has thin-looking hair
