Why do African Americans have a higher early puberty rate (50%) than whites (15%)?
African Americans favored shampoos with clinically active high doses of estrogen. They also used them on their children. In 1998 Tiwary, now retired, published a study of four girls – including a 14-month-old – who developed breasts or pubic hair months after beginning to use such products. The symptoms started to disappear when they stopped using them. The year before, he published a study showing that some of the products used by his patients contained up to one milligram (1 mg/oz) of estradiol per one ounce of shampoo. By comparison a normal adult topical skin dose for estradiol is 0.02-0.05 mg/day. This means that one ounce of shampoo contains 50 times the daily ADULT dose of estradiol. A small handful of this shampoo on your child every day may give her OR HIM breasts! Estrogen in shampoo triggers early puberty. See the article here.
