Before having a look at the term "normal hair loss" we should have a look at "hair" in general. An average head consists of 100,000 to 150,000 hair, which grows ½ an inch every month. Hair is growing due to rapid cell division at the base of the follicle and gets pigmented when it is pushed upwards out of the follicle.

Normal hair loss or alopecia, is a part of the natural hair life cycle.
