Chemical hair relaxers are a type of lotion or cream that makes tight curls or very curly hair easier to straighten by chemically “relaxing” the curls. Chemical hair relaxing causes the hair to straighten by permanently altering the structure of the hair.

For frequent users of hair relaxing products, the thought that this process could potentially be the cause of life-threatening harm is devastating. Unfortunately, there have been numerous studies linking frequent use of hair straighteners or relaxers to increased risk of uterine cancer and ovarian cancer, in addition to other medical issues. And manufacturers of hair relaxing products must be held liable for failing in their duty to adequately warn of the risks.

If You Believe You Have a Claim, Keller Postman Can Help

If you suspect that the use of hair relaxer products may be responsible for your cancer diagnosis, Keller Postman can help you file a lawsuit against the company that manufactured the product(s) you used and may be responsible for contributing to your illness.

Keller Postman is fighting for victims who were not properly warned of the risk that hair relaxers could potentially cause cancer, including ovarian cancer and uterine cancer. If you believe you may qualify for a lawsuit, we encourage you to fill out our Free Case Evaluation form. One of our attorneys will contact you to gather more information and begin your claim.

Hair Relaxers’ Scientific Link to Cancer

A series of studies have been published linking uterine cancer, ovarian cancer, and potentially uterine fibroids and breast cancer to chemical hair relaxers. In a statement given to the New York Times, Alexandra White, head of the environment and cancer epidemiology group of the National Institute of Environmental Health Sciences (N.I.E.H.S.), said that they have “seen this association between hair straighteners and… ovarian and now uterine cancer — it’s been a consistent finding among hormonally driven female reproductive cancers.”

Use of Hair Relaxers and Racial Disparity

Chemical hair straighteners and relaxers are common in the United States and are often used beginning in childhood, particularly among Black women. Black women are also known to have significantly higher rates of certain types of cancer – particularly uterine cancers – than white women. Rates of uterine cancer have been rising recently among all women in the United States, but Black women die of uterine cancer at twice the rate that white women do, one of the largest racial disparities reported for any cancer. Black women also face aggressive marketing of hair relaxer products, and are often pressured to adhere to European beauty norms, particularly in schools and in the workplace.

Hair Relaxer Lawsuits on the Rise

Women across the country are now bringing hair relaxer lawsuits against companies that manufacture these products. These women, plaintiffs in the lawsuits, used hair relaxers at least five times (but usually far more frequently) and were subsequently diagnosed with hormone-dependent cancers, which depend on a hormone for growth and/or survival. These types of cancers include ovarian cancer and uterine cancer.

Defendants in these cases include manufacturers of hair relaxers, largely cosmetic companies. L’Oreal USA is the most well-known hair relaxer manufacturer and the largest cosmetics company worldwide. Other manufacturers may include Revlon Consumer Products Corporation, Softsheen Carson, and Strength of Nature LLC.

Who qualifies for a hair relaxer lawsuit?

If you were diagnosed with uterine cancer (endometrial and non-endometrial) or ovarian cancer and used chemical hair straightening/hair relaxing products at least five times, you may qualify for a lawsuit. Please fill out a free case evaluation form and we will evaluate your case. If you qualify, we will help you file a hair relaxer lawsuit against the manufacturer of the product that you used.

Research is currently being conducted to identify the specific carcinogens responsible for injury and the full spectrum of individual products and brands that may contribute to this injury. We advise women who are using these products to lessen the frequency of use or stop using hair relaxing/straightening products altogether until this research is finalized. We will update this page as soon as we can definitively advise on the most harmful products.

While most states have statutes of limitations that determine the timeframe in which plaintiffs must file a claim, the majority of women who have developed cancer as a result of hair relaxer use have not missed the window of opportunity to bring a lawsuit. However, we urge you not to wait and encourage you to contact an attorney as soon as possible. Please fill out a free case evaluation form and someone from our team will reach out as soon as possible.

This litigation will eventually be resolved through a negotiated settlement with defendants. Unfortunately, the compensation that plaintiffs will receive is currently unknown and difficult to forecast. However, as soon as we can predict the compensation that victims will receive, we will share an update here.

We unfortunately cannot predict with any certainty how long it will take for cases to resolve, as litigation is unpredictable. There is no way to know just yet. But we will keep this page updated and also ensure that our clients are notified with any key developments.

We will pursue your claim on a contingency fee basis, meaning that there is no upfront payment, fees, or expenses until we win your case and recover money on your behalf.

No, it does not. Our consultations are always free. If we believe you have a case, we will pursue your claim on a reasonable contingency fee basis. You pay nothing unless we win.


Hair Straightening Chemicals Associated with Higher Uterine Cancer: This study from the National Institutes of Health shows that “women who used chemical hair straightening products were at high risks for uterine cancer compared to women who did not report using these products. The researchers found no associations with uterine cancer for other hair products that the women reported using, including hair dyes, bleach, highlights, or perms.” The study also found that Black women “may be more affected due to higher use.”

Use of Hair Products in Relation to Ovarian Cancer Risk: This article evaluates whether endocrine disruptors within hair relaxers that can be absorbed into the bloodstream are related to ovarian cancer incidence. The findings “suggest that frequent use of hair straighteners/relaxers or pressing products, which are primarily used by African American/Black women… may be associated with the occurrence of ovarian cancers.”


Current Status: Keller Postman continues to file new cases on behalf of women who claim their hair relaxing products caused them to develop cancer, specifically uterine and ovarian cancer. We are currently working with victims to gather evidence, collect medical records, and file their cases in the appropriate venue. If you believe you have a claim, please contact us.

February 6, 2023: The United States Judicial Panel on Multidistrict Litigation (JPML) consolidated over 50 hair relaxer lawsuits, transferring them to the U.S. District Court for the Northern District of Illinois before Judge Mary M. Rowland. This will help streamline discovery and pre-trial proceedings for plaintiffs who allege that the hair relaxing products they used were linked to cancer and other reproductive health problems.
