Natural hair that is subjected to constant physical trauma from excessive brushing or combing, tight braids or ponytails, or extreme scratching or massage can cause hair at the temples to become weak and to stop growing to its normal length. Clean shaving, especially for men, can cause white bumps to appear on the area where the hair was shaved short, and at times can become infected with pus and leave permanent scarring, affecting hair growth.
As they age, men tend to lose the hair on top of their head, which eventually leaves a horseshoe-shaped ring of hair around the sides. This type of hair loss is called male-pattern baldness. It's caused by genes (from both parents -- the idea that men take after their mother's father is a myth) and it's fueled by the male hormone, testosterone. In female-pattern baldness, the hair loss is different -- it thins throughout the top of the scalp, leaving the hair in front intact.
According to practitioners of traditional Chinese medicine, hair health is tied to two things: kidney energy and the blood, which nourish the hair. The solution: acupuncture and Chinese herbs.

In order to understand why, first it’s important to know how your hair grows.
