“We do not believe the science supports a link between chemical hair straighteners or relaxers and cancer,” Revlon told Reuters. Researchers observed that women who regularly used permanent hair dye during the year before they enrolled in the Sister Study had a 9% higher risk of developing breast cancer. Women who used semi-permanent or temporary hair dye had little or no increased risk. This is the latest study to look at possible links between cancer and chemical hair products. Participants are American women who did not have cancer when they enrolled in the study but who had a sister diagnosed with breast cancer. Researchers found that women who used permanent hair dye or chemical straighteners were at higher risk of developing breast cancer.

Three of these chemical hair straightener lawsuits allege uterine cancer. The Environmental Protection Agency (EPA) will add certain phthalates, such as DINP, to its list of harmful toxic chemicals subject to increased regulations and reporting requirements. This is significant because DINP and other phthalates are chemicals in hair relaxer products believed to disrupt the hormone system and increase the risk of uterine and ovarian cancer. The EPA’s decision to regulate these chemicals is based on evidence of their link to cancer. New research raises concern about the safety of permanent hair dye and chemical hair straighteners, especially among African American women. The study was published Wednesday in the International Journal of Cancer.

In 2021, a research article from NIH reported that the results of a major long-term study found an association between the use of chemical hair relaxers and higher rates of ovarian cancer. The study showed that women who regularly used hair relaxer (more than 4 times per year) displayed a 50% increased risk of ovarian cancer. New hair relaxer lawsuits filed in federal courts continue to be filed. There are over 200 pending hair relaxer cases across the country, most of which have already been transferred into the MDL.

One study published last year showed that repeated use of hair straightening products, which are sometimes called relaxers, could more than double the risk of uterine cancer. Women who used chemical hair-straightening products were at higher risk for uterine cancer compared to women who did not report using these products, according to a new NIH study. The researchers found no associations with uterine cancer for other hair products that the women reported using, including hair dyes, bleach, highlights or perms. Of the women who didn’t use chemical hair straighteners in the previous year, 1.6% developed uterine cancer by age 70. Conversely, about 4% of the women who used chemical hair straighteners at least 4 times in the previous year were diagnosed with cancer, equaling a 2-fold increased risk.

Our writers are members of professional associations, including American Medical Writers Association, American Bar Association, The Alliance of Professional Health Advocates and International Society for Medical Publication Professionals. The defendants named in the motion include L’Oreal USA, Inc. and a handful of smaller, non-public companies. But their lawyers will probably request an alternative venue other than Chicago, Illinois, that they view as more favorable. Unless large blocks of plaintiffs choose to strategically sit on the sidelines, we fully expect the number of cases in the MDL to increase even more dramatically moving forward.
Black women using hair relaxers face higher cancer risks
“Not statistically significant” sums up much of the research results involving hair dye and the risk of other cancers, such as non-Hodgkin lymphoma, leukemia and uterine cancer. Permanent hair dyes, which make up about 80% of the market, typically have more chemicals than semi-permanent and temporary hair dyes. Darker hair dyes often have higher concentrations of chemicals and carcinogens, too. Certain hair straightening or smoothing products release formaldehyde when they’re applied to the hair and processed and sealed with a heat treatment. The cancer-causing effects of hair straightening and relaxing products disproportionately affect Black women.

While the study didn’t find that the link between straightener use and uterine cancer risk was different by race, the effects may be greater for Black women because they’re more likely to use these products. The researchers did not find links between uterine cancer and the use of other hair products, including hair dyes, highlights, and perms. The study data includes 33,497 U.S. women ages participating in the Sister Study, a study led by the National Institute of Environmental Health Sciences (NIEHS), part of NIH, that seeks to identify risk factors for breast cancer and other health conditions. The women were followed for almost 11 years and during that time 378 uterine cancer cases were diagnosed. A new study finds that women who often use hair straightening chemicals may face higher risk of uterine cancer.
Can Hair Dye Increase Cancer Risk?
Although some individual studies have shown associations between hair dye use and the risk of leukemia, a meta-analysis of 20 studies showed a small association that was not statistically significant (19). In addition, a large cohort study found no association between ever use of hair dye and the risk of leukemia but very slightly increased risks of basal cell carcinoma (particularly in women with naturally light hair) and ovarian cancer (12). In 2019, researchers used data from the same study to to report an association between the use of hair dye and relaxers and breast cancer rates in women who were already at an increased risk level of getting breast cancer. It’s important to note that researchers are still studying the link between chemical hair straighteners and cancer. Phthalates are commonly referred to as “plasticizers” because they are chemicals that are durable to certain types of pliable plastics.

In 2018, when she was just 28 years old, Mitchell was diagnosed with uterine cancer. New Hair relaxer lawsuits continue to get directly filed in the Northern District of Illinois, which houses all of the class action lawsuits. Both black and white women who used hair straighteners were about 30% more likely to develop breast cancer than those who didn't use the products. However, black women are more likely to use them, with about 75% of black women in the study reporting they straighten their hair.
In her initial Case Management Order, Judge Rowland indicated that there will be a single steering committee. She will also name lead counsel (responsible for handling the bellwether trials) and liaison counsel. The defendants in the hair relaxer MDL are pushing for a bifurcated discovery process that would limit the initial discovery phase to the issue of general causation (i.e., evidence linking hair relaxer to cancer). Discovery on other issues would only begin after that initial causation phase is completed.
Phthalates are widely used in various cosmetic products, including chemical hair relaxers. EDCs are types of chemicals that impact and disrupt the endocrine system and interfere with hormone receptors. As predicted, Judge Mary Rowland has upheld the majority of claims in the class action lawsuit against major hair relaxer manufacturers. The MDL judge’s ruling pushed back on the defendants’ weak preemption argument, finding that federal law does not invalidate the plaintiffs’ state law claims, particularly those alleging negligence and product liability. Warranty claims under state law and the Magnuson-Moss Warranty Act also met the standards for continuation. Healthline could not immediately reach L’Oreal and Revlon for comment, but both companies told Reuters their products undergo rigorous safety reviews.
