EDCs in hair products can be absorbed through the skin and could elevate endogenous hormone levels.
Edcs in hair products. This study reviews the current state of the science associating one such means of exposure hair products containing EDCs with breast cancer risk in African American women. We found a growing body of evidence linking. 1 environmental estrogen and EDC exposures to breast cancer risk 2 the presence of such chemicals in personal care products including hair products and 3 the use of certain hair products.
They focused their research on cataloguing the concentrations of 66 endocrine-disrupting chemicals in 18 popular hair products. The products spanned six categories including hot oil treatments relaxers hair lotions leave-in conditioners root stimulators and anti-frizz products. They selected the products based on survey results that indicated the most frequently used products.

Many hair products as well as other cosmetics skin-care products and makeup contain endocrine-disrupting chemicals including xeno-estrogens. These are often intentionally added to the formulas. In small doses most people may not feel any impact whereas some people might have an immediate reaction.
The hair products tested contained 45 endocrine disrupting or asthma-associated chemicals including every targeted chemical class. We found cyclosiloxanes parabens and the fragrance marker diethyl phthalate DEP at the highest levels and DEP most frequently. Root stimulators hair lotions and relaxers frequently contained nonylphenols parabens and fragrances.
Anti-frizz products contained cyclosiloxanes. As environmental estrogen and EDC exposures have been associated with breast cancer risk and the presence of such chemicals are found in personal care products including hair products this review assesses associations between hair products known or suspected to contain such ingredients and breast cancer risk in African American women. Endocrine-disrupting chemicals EDCs include substances in our environment water food and personal care products that interfere with the production transport breakdown binding and elimination of hormones.
Exposure to these chemicals ultimately affect the balance of the body that could lead to a number of health problems including weight gain hypothyroid infertility adrenal. Phthalates tha-lates are a petroleum-based group of chemicals used in all kinds of products. They are a type of endocrine-disruptors EDCs that causes issues with reproductive health.
Many types of phthalates have been banned in the EU and each year they seem to be reducing the amount allowed mainly in childrens products.

Triclosan is another preservative-slash-EDC that can interrupt healthy hormone function. Its mostly used in water-based products such as shampoo and conditioner. And even though it keeps those products from going rancid it also keeps your hair from growing.

In the case of the PB family its main use in cosmetic products and PCPs is due to their antimicrobial properties 21. Select hair products contain endocrine disrupting chemicals EDCs that may affect breast cancer risk.
We hypothesize that if EDCs are related to breast cancer risk then they may also affect two important breast cancer risk factors. Age at menarche and mammographic breast density. Additional references to EDCs were mead in regulation EC 19072006 concerning the Registration Evaluation Authorization and Restriction of Chemicals REACH in Regulation EC 12232009 on cosmetic products and in the EU Regulation on Food Contact Materials.
The Commission and Member States continue to participate in the OECDEndocrine Disruptor Testing and Assessment Task Force.
