How hair grows

It all starts with the hair follicles in the pockets of the growth of skin tissue, which live buried in the scalp where the hair begins with groups of 1-4 hairs. 2-8 years at a time when the follicles are constantly working on hair growth and push up and over the scalp with a rate of about one half inch per month. Finally, every hair into a resting phase stops and the hair grows. Finally, the hair falls in the follicle, the hair is not life itself, and instead provides a new spring, and repeat the cycle.
