Research has shown that 95% of female "patchy" baldness, scientifically known as alopecia areata, is due to heredity. Studies have shown that one in four women are affected by alopecia areata. If you are experiencing abnormal hairloss, first contact your health provider to make sure that you do not have a serious medical condition. It is COMPLETELY normal to shed up to 150 hairs per day. If you notice your hair is actually thinning, or coming out in clumps and causing bald spots, this is not normal shedding. Men experience balding much more frequently than women.  Most male balding is also due to heredity. Provillus hair loss treatment targets the specific needs of both men and women to stimulate new hair growth.
