Androgenic alopecia--hair loss caused by genetics combined with the aging process and hormonal changes for both men and women--is the leading cause of hair thinning. According to "Hairfinder," approximately 40 percent of both men and women experience some degree of hair loss by age 35. In men, hair loss can begin as early as the late teens or early 20s. The genetic thinning pattern appears differently in men and women. Men usually experience thinning first at the front hairline and the crown. For women, in particular, menopause means a decrease in estrogen production. This decrease in estrogen in turn causes the hair to generally thin all over the head. The Dermaheal Cosmeceutical hair care products are the safest and most powerful hair loss products available without a prescription. Our products not only concentrate on preventing hair loss but help slow thinning and stimulate hair growth safely and effectively for both men and women.
