There are many reasons why hair loss in women occurs. The most common reasons have to do with changes in hormones, for instance during pregnancy, after childbirth or during menopause. However, other reasons why hair loss in women occurs has to do with genetics, just like men. Also, why hair loss in women occurs at other times in their lives is still a mystery. Scientists have been delving into the idea that other genes denote whether a person, male or female, loses their hair. However, just like men, a woman can get a hair transplant and get her hair back.
