When a woman suffers from hair loss, it can have several causes. For many women, hair loss is caused by hormonal fluctuations. Hormone fluctuations affect the hair growth cycle. Many women also experience hair loss during or after pregnancy; changing hormones during pregnancy, stress and tension can cause hair loss.
