Alopecia areata â an autoimmune disease that affects up to 2% of the population. It causes round patches of hair loss and can lead to total baldness. In many cases, the hair regrows. There are about 50 different hair loss disorders among men and women.
Receding hairline can occur as a result of taking drugs, alcohol, having gone through a trauma or surgery, being slowly poisoned, after effects of childbirth, or as a symptom of an ailment. One of the main causes of receding hairline in women is the reduction of their estrogen levels. Similarly men can experience more hair fall when their testosterone levels decrease and that is why this problem is associated with ageing.
