Hair Relaxer Uterine Cancer Lawsuit: 2026 MDL Update

If you used chemical hair relaxers for years and were later diagnosed with uterine cancer, you may be wondering whether the two are connected. You are not alone in asking. A hair relaxer uterine cancer lawsuit is now one of the largest product-liability fights in the country, and the case reached an important turning point this month.

This post explains, in plain terms, what just changed in the litigation, what the science actually says, and who may be affected. It is general information, not legal advice about your specific situation.

What is the hair relaxer litigation about?

Thousands of women have filed claims alleging that chemical hair straighteners and relaxers caused their cancer. They also allege that manufacturers failed to warn about the risk for years. The claims center mainly on uterine cancer, along with endometrial and ovarian cancer.

Because these cases share common facts, the federal courts grouped them into a single proceeding. It is called multidistrict litigation, or an MDL. Think of an MDL as a way to handle many similar cases together, so that shared questions get decided once instead of thousands of times.

The hair relaxer cases sit in MDL 3060 before U.S. District Judge Mary M. Rowland in the Northern District of Illinois. According to court records and MDL trackers, roughly 11,877 cases were pending as of July 1, 2026. As a result, it is now the fourth-largest active MDL in the nation.

What just changed in the hair relaxer uterine cancer lawsuit?

In July 2026, the court took a firmer hand in steering the litigation toward its first trials. Judge Rowland took direct control of choosing the “bellwether” cases. A bellwether is a test case: a representative claim tried early so both sides can gauge how juries may respond.

Instead of letting the parties trade picks, the judge widened the pool of cases in discovery and pushed for more trial-ready candidates. In addition, she set case-specific expert and summary-judgment deadlines, with key motions due November 16, 2026. First trials are broadly expected in 2027.

The court also narrowed which cases are eligible for the bellwether pool. For now, the eligible group is limited to uterine, endometrial, or ovarian cancer claims that met the court’s earlier filing requirements. Still, that eligibility cutoff applies to the test-case pool, not to whether a person can pursue a claim at all.

Because the litigation is still in the expert and motion phase, no court has decided that hair relaxers cause cancer, and no company has been found liable. There is also no settlement. These are contested claims moving through the normal steps of a large case.

What does the science say?

The lawsuits lean heavily on a widely reported study. In 2022, researchers using data from the 2022 NIH-funded Sister Study reported a link between chemical hair-straightening products and uterine cancer. The findings appeared in the Journal of the National Cancer Institute.

The study followed more than 33,000 women. Women who reported frequent use of straightening products, defined as more than four times in the prior year, were about twice as likely to develop uterine cancer as women who did not use them. However, the authors described an association, not proof that the products cause cancer.

Researchers pointed to chemicals sometimes found in these products, such as parabens, bisphenol A, metals, and formaldehyde, as possible contributors. Notably, the study also found that Black women used these products more often and started younger. For that reason, the authors said the findings may be especially relevant for Black women.

Who may be affected?

People often ask whether their history fits the pattern the lawsuits describe. In general, the claims tend to involve women who:

• Used chemical hair relaxers or straighteners regularly, often over many years
• Were later diagnosed with uterine, endometrial, or ovarian cancer
• Used salon or at-home products marketed for straightening or relaxing hair

Even if that describes your history, eligibility still depends on the facts and on the law where you live. Deadlines to file, known as statutes of limitations, vary by state and can be short. Because of that, it is wise to ask an attorney promptly rather than assume a deadline has or has not passed.

Frequently asked questions

Is there a hair relaxer settlement yet?

No. As of July 2026, there is no settlement in the hair relaxer MDL. The litigation is still in the expert and pretrial phase, with the first bellwether trials expected in 2027.

Does using hair relaxers mean I have a case?

Not automatically. Using the products and later developing uterine, endometrial, or ovarian cancer may support a claim. However, whether you qualify depends on your specific facts, your medical history, and the deadlines in your state.

How long do I have to file a hair relaxer uterine cancer lawsuit?

That depends on where you live. Filing deadlines differ from state to state and can be short, so it is best to confirm your deadline with an attorney as soon as possible.
