About PLACENTAL EXTRACT: This ingredient is derived from the placenta, an organ that develops in female mammals during pregnancy, lining the uterine wall and attached by the umbilical cord to provide nourishment and oxygen to the fetus. The placenta produces progesterone, estrogen, and other hormones, which raise potential health concerns in personal care products. In one study four girls between one and eight years of age developed breasts or pubic hair two to 24 months after starting the use of estrogen- or placenta-containing hair products. Their breasts and public hair regressed when they stopped using the products. No other cause for early sexual development was found. (Tiwary 1998).
