A recent study published in the Journal of Cancer has uncovered a concerning association between commonly used hair products and an increased risk of breast cancer in women. The research indicates that permanent hair dyes and chemical straighteners or relaxers may contribute to higher rates of breast cancer, particularly among certain demographic groups.
While temporary or semi-permanent hair colors were not found to pose any associated dangers during the study, the use of permanent dyes was shown to be prevalent, with an estimated one in three women in the United States utilizing these products. Notably, the risk of breast cancer was significantly higher in Black women who regularly used these dyes, especially those who applied them every five to eight weeks. The study revealed that these women faced a staggering 60% higher risk of developing breast cancer.
Moreover, the use of chemical straighteners and relaxers, primarily popular among Black women, was found to be even more concerning. The study demonstrated that 74% of Black women who used these products with the same frequency faced an elevated risk, while only 3% of White women experienced a similar increase.
Scientists involved in the research suggest that the composition of products tailored for Black hair might contain more hormonally-active compounds and carcinogens, contributing to the heightened risk among this demographic. Dr. Dale Sandler, coauthor of the study and chief of the NIEHS Epidemiology Branch, emphasized the complexity of breast cancer development, stating, “We are exposed to many things that could potentially contribute to breast cancer, and it is unlikely that any single factor explains a woman’s risk.”
As a precautionary measure, Dr. Sandler recommended that women consider avoiding these chemicals to potentially reduce their risk of breast cancer. While further research is necessary to establish a conclusive recommendation, this study underscores the importance of being mindful of the products used and their potential health implications.
