On its website, Mizani has only six reviews for its Butter Blend Relaxer; all six give the product five stars and rave about its results.
The website includes instructions about how to use the hair straightening product, including some warnings of what to avoid. “DO NOT apply to scalp,” reads one such cautionary message. “DO NOT exceed recommended timing,” goes another.
Yet a third warning could be included in the product packaging: Frequent use of chemical hair relaxers has been linked to numerous serious illnesses, including cancer.
Mizani Hair Relaxer Cancer and Illness Risk
Scientific research has linked chemical hair relaxers to ovarian cancer and uterine cancer. These findings are particularly concerning for Black women, who use hair straightening products at a higher rate and more frequently than other consumers.
Hair relaxer products are linked to endometriosis through the prevalence of the chemical phthalate DEHP. Endometriosis is a condition caused by tissue that lines the uterus beginning to grow outside the uterus, according to the Mayo Clinic. The cause is unknown.
Uterine fibroids were linked to the frequent use of hair relaxer products in a 2012 study published in the American Journal of Epidemiology. Uterine fibroids, also called leiomyomas or myomas, are growths that occur in the uterus and can, in rare cases, lead to cancer. Black women are three times as likely to develop uterine fibroids as their white counterparts.
A 2019 study by scientists with the National Institutes of Health (NIH) documented a link between the use of chemical hair straighteners and breast cancer. According to those findings, women who used hair relaxer products every two months or more frequently were 30 percent more likely to develop breast cancer during the course of the study. Though often linked to a family history of breast cancer, the Mayo Clinic describes the disease as “caused by a complex interaction of your genetic makeup and your environment.”
Most recently, a 2022 study found women who frequently use chemical hair relaxers were more than twice as likely to develop uterine cancer. As stated in the report, “hazardous chemicals,” including those that are endocrine-interrupting and/or carcinogenic, could be responsible for the link to increased uterine cancer occurrence. These chemicals could include: parabens, Bispheonol A, formaldehyde, and metals.
