Silvia Pagen Westfall in Boston, without the knowledge of many parents, said that some hair products, especially some products sold to black people, contain a small amount of hormones that may lead to girls The evidence that hair products containing estrogen lead to early puberty is largely indirect, and this has not yet been confirmed. But Ella Toombs, acting director of the cosmetics and color Office of the Food and Drug Administration of the United States, told New scientists and Cologne; “No amount [of oestrogen] Is considered safe and can be included inthe-Counter products. According to FDA regulations, excessivethe- Counter products containing hormones are drugs and therefore need special approval. However, there seems to be a gray area for the products sold before 1994. The FDA has failed to respond to requests to clarify this position. At least five companies are still producing hormones. The industry insider, who declined to be named, told the New Scientist that hair contains products. Throughout the West, girls tend to advance into puberty. Everything from improving diet to environmental contaminants is blamed. But African- American girls develop earlier than white girls. A study found that about half of black girls in the United States began to develop breasts or pubic hair at the age of eight, compared with only 15 white girls. In Africa, regardless of socio-economic status, girls enter puberty much later. This huge difference can be explained by using hormones more frequently, at least in part because The former pediatric endocrine director of the Brook Army Medical Center in Texas, Chandra Tivey, said he contains African-American hair products. \"I believe that if the children do not use these hair care products, the frequency of precocious puberty will decrease,\" he said . \". These products are sold in the form of shampoo or deep care The hair is dry and crisp. These labels generally indicate that they contain placenta, hormone, or \"estrogen\", although not all products that make this statement contain active hormones. Although the New Scientist survey shows that such products are no longer sold in Europe, there are still many products available on the internet around the world. They are still very popular among African-Americans. Su-published a small study earlier this year Li Ting of the Seattle Institute for Children\'s Health believes that nearly half of Africans Parents in the United States use this product, which most parents also use on their children. This figure is less than ten per cent for other ethnic groups. Tiwary told the New Scientist that he had conducted a larger, unpublished survey of families in 2000, confirming the findings. In 1998, retired Tiwary published a study of four girls, including a 14-year-old girl. month- Old-a few months after starting to use these products, the person who developed the breast or pubic hair. When they stopped using, the symptoms began to disappear. A year ago, he published a study showing that some of the products used by his patients contained up to 4 mg of estrogen per 100 grams. Each other 100 grams contains two grams of oestriol. For example, B & B Super Gro was listed before 1994 and is still being sold in the United States, claiming to be \"hormone-rich\" and found it to contain 1. Oestriol 6g per 100g. While the level of oestriol in these products is much higher, oestradol is a more effective form of estrogen. There is no doubt that estrogen is easily absorbed through the skin-hormone therapy is usually done through patches. Long- Long-term exposure to these doses may lead to early puberty, Tiwary believes. His research is not the only one that suggests an impact. Anecdotal reports in the 1982 scientific paper describe children\'s early puberty after using hair therapy and certain ointment. Tiwary informed the FDA of his concerns on 1994, but said he had never received a response. Evidence of estrogen Hair products containing early puberty are still limited. There are too many other suspicious substances to blame in the absence of further study. \"A person is not only exposed to a chemical, but a mixture of a variety of chemicals,\" said Julia Brodi, director of the Silent Spring Institute in Massachusetts. Profitable organizations that focus on the environment and women\'s health. \"People are increasingly aware of the presence of hormone-active compounds in cosmetics.
