The Connection Between Breast Cancer and Hair Relaxers and Hair Straighteners
The National Institute of Environmental Health Sciences (NIEHS) published findings of the Sister Study, including data from over 33,000 women who were tracked for nearly 11 years.
Within that time frame, 378 women were diagnosed with uterine cancer, and those who used hair straighteners over four times in the previous year “were more than twice as likely to go on to develop uterine cancer compared to those who did not use the products.”
Around 60% of the women who reported using hair straightening products self-identified as Black, the press release states.
Other research studies showed similar alarming results.
According to The National Library of Medicine: “Hair relaxers and leave-in conditioners and oils, commonly used by Black/African American women, may contain estrogens or estrogen-disrupting compounds. Thus, their use may contribute to breast cancer risk.”
Also, researchers studied data from Boston University’s Black Women’s Health Study, which followed 59,000 self-identified African American women for over 25 years.
The research team found that frequent and long-term use of lye-based relaxers may increase the risk of breast cancer among Black women, compared with more moderate use.
The research team also found that “Black women who used hair products containing lye at least seven times a year for 15 or more years had an approximately 30% increased risk of estrogen receptor-positive breast cancer compared with more infrequent users.”
The Shield Legal Network team offers victims diagnosed with breast cancer after using hair relaxers and hair straightening products a free, private case evaluation to seek justice and potential compensation.
