Just like the rest of your body, your hair can be healthy or unhealthy. Your hair grows in cycles, with each hair falling out after about 2 to 6 years of growing. If your hair follicle is healthy, a new hair will grow where the old one fell out. Hair growth is controlled by male hormones that both men and women have. There are many ways your hair health can be affected, from losing your hair to scalp infections to split ends.
