Each strand of hair on the human body is at its own stage of development. Once the cycle is complete, it restarts and a new strand of hair begins to form. The rate or speed of hair growth is about 1.25 centimetres or 0.5 inches per month, or about 15 centimetres or 6 inches per year.
When you are born, you have the same number of hair follicles as you do today. They are part of your skin, and it is impossible to grow more of them. Once enlightened, you might ask yourself, if not possible to regrow, whether or not you can stimulate hair follicles as a form of hair stimulation to encourage growth. Strictly speaking, hair growth stimulation is not possible either.
