Have you or a loved one used hair-straightener chemicals? If so, and you subsequently developed uterine cancer, the chemicals may be the cause. Fill out the form on this page to learn more.

Chemical hair straighteners and relaxers are a billion-dollar industry, but research suggests these “beauty treatments” may have serious health risks.

A long-term study by Boston University’s Black Women’s Health Study (BWHS) found that frequent use of chemical hair relaxers may increase the risk of developing uterine cancer. Now, a class action lawsuit investigation is targeting major brands allegedly linked to these cancer claims.

If you were diagnosed with uterine cancer after regularly using chemical hair straighteners or relaxers, you may be eligible to seek compensation.

If you or a loved one developed uterine cancer after regularly using chemical hair straighteners or relaxers, you may be eligible to file a lawsuit. Legal action could help you recover compensation for medical bills, pain and suffering, and even wrongful death.

Boston University’s Black Women’s Health Study (BWHS) began in 1995 to better understand why Black women face higher rates of medical conditions like hypertension, early-onset breast cancer, diabetes, stroke and lupus. The study has followed the health of more than 59,000 self-identified Black women since its launch.

Recent findings from BWHS suggest that moderate to heavy use of chemical hair relaxers may increase the risk of uterine cancer, particularly among postmenopausal Black women.

“Our study suggests that moderate and heavy use of chemical hair relaxers may be associated with a higher risk of uterine cancer among postmenopausal Black women… Black women have higher rates of aggressive subtypes of uterine cancer and are nearly twice as likely to die from their disease,” said Kimberly Bertrand, Sc.D., associate professor of medicine at Boston University Chobanian & Avedisian School of Medicine.

An additional 2022 study also found a link between hair straightener use and uterine cancer across all age groups.

What is the hair relaxer cancer lawsuit about?

Based on findings from the Black Women’s Health Study and other scientific research, consumers are now filing lawsuits against major beauty brands — including Revlon, L’Oréal and others — alleging that chemical hair straighteners and relaxers caused uterine cancer.

The lawsuits allege these companies knew or should have known about the potential health risks but continued to market and sell dangerous products.

Both companies have denied any wrongdoing.

“We do not believe the science supports a link between chemical hair straighteners or relaxers and cancer,” Revlon said in a statement to Reuters.

L’Oréal responded that its products have a “rich heritage and history” rooted in Black entrepreneurship and that the company remains committed to offering the best products “for all skin and hair types, all genders, all identities, all cultures, all ages.”

Who qualifies to join the hair relaxer lawsuit?

If you or a loved one used chemical hair straighteners or relaxers and were later diagnosed with uterine cancer, you may be eligible to join the ongoing lawsuit investigation. These legal filings can seek compensation for medical bills, pain and suffering, and other damages related to the illness.

Family members of those who have passed away from uterine cancer linked to hair relaxer use may also qualify to file wrongful death lawsuits.
