New Study Finds Link Between Hair Products and Higher Risk of Cancer in Women
A recent study published in the Journal of Cancer has uncovered a concerning correlation between widely-used hair products and an increased risk of cancer in women. The research specifically focused on permanent hair dyes and chemical straighteners or relaxers, revealing their potential relevance to rates of breast cancer.
According to estimates, approximately one in three women in the United States use permanent hair dyes, making this finding particularly significant. Temporary or semi-permanent hair colors did not display any associated dangers during the study.
The study also highlighted that straighteners and relaxers are predominantly used by Black women. Scientists believe that the high absorption capacity of thick or coarse hair leads to a higher intake of dyes. Furthermore, products specifically targeted towards Black hair were found to contain more hormonally-active compounds and carcinogens.
The research involved data collected from an extensive group of 46,709 women between the ages of 35 and 74 over a span of eight years. Findings revealed that Black women who used dyes at least every five to eight weeks were 60% more likely to develop breast cancer. In contrast, white women who used the dyes demonstrated an 8% increased risk.
Even more alarming, chemical straighteners and relaxers posed an even greater hazard. Among Black women who used these products every five to eight weeks, a whopping 74% showed an increased risk of breast cancer. In comparison, only 3% of White women using these products faced an elevated risk.
Dr. Dale Sandler, co-author of the study and chief of the NIEHS Epidemiology Branch, emphasized that multiple factors contribute to a woman’s risk of developing breast cancer. However, he stated, “While it is too early to make a firm recommendation, avoiding these chemicals might be one more thing women can do to reduce their risk of breast cancer.”
These findings shed light on the potential dangers associated with widely-used hair products and the significant disparities in risk between different racial groups. It underscores the need for further research and awareness to ensure the safety and well-being of women who use these products regularly.
