Over the course of your life you will go through many shifts in the balance of your body’s hormones. For men, these shifts are usually due to the natural aging process. A man can also produce hormonal shifts by using anabolic steroids. In either case, hair loss is often the end result.
For women, going through the processes of pregnancy and childbirth can cause hormonal swings that result in thinning hair. The hormonal changes associated with menopause are also a major cause of hair thinning for women.
