Written by Hair Relaxer Lawsuits in Chicago Federal Court: What Claimants Should Know
Thousands of women across the United States have filed lawsuits alleging that long-term use of chemical hair relaxers caused serious health conditions, including uterine cancer, uterine fibroids, and ovarian cancer. Those cases are now centralized in Chicago federal court, making this an important issue for Illinois women and their families. If you are wondering about the hair relaxer lawsuit who qualifies, this article explains the litigation landscape, the research behind it, and what prospective claimants should understand before speaking with an attorney.
This article provides general legal information; consult a licensed Illinois attorney for advice specific to your situation.
The Chicago MDL: Where These Cases Are Consolidated
Federal multidistrict litigation (MDL) allows related cases from across the country to be transferred to a single court for coordinated pretrial proceedings. The hair relaxer cases are consolidated in the Northern District of Illinois under MDL 3060, styled In re: Hair Relaxer Marketing, Sales Practices, and Products Liability Litigation, before the Honorable Mary Rowland in Chicago.
MDL consolidation does not mean all plaintiffs share a single case. Each individual plaintiff retains her own claim. The MDL process coordinates discovery, expert witness proceedings, and pretrial motions so that courts and parties are not duplicating effort across hundreds of individual lawsuits. If the MDL does not settle globally, individual cases can be remanded to their home districts for trial.
As of the date of this publication, MDL 3060 remains active. Product liability MDLs of this scale typically proceed through years of pretrial litigation before bellwether trials or settlements are reached. Claimants and their attorneys should follow case developments closely and should not rely on projections or timelines circulating in media coverage.
The Research Behind the Claims
The litigation draws significantly on a peer-reviewed study published in the Journal of the National Cancer Institute in 2022. Researchers Alexandra White, Dale Sandler, and colleagues, working through the National Institutes of Health and National Cancer Institute Sister Study, analyzed data from more than 33,000 women enrolled in the Sister Study cohort. The study found that women who reported frequent use of chemical hair straightening products — defined as more than four times per year — had roughly twice the risk of developing uterine cancer compared to women who did not use those products. The study, referred to as Chang et al. 2022 (JNCI), has been widely cited in the MDL proceedings as support for the biological plausibility of plaintiffs’ claims.
The NIH/NCI Sister Study is a long-running cohort study following sisters of women diagnosed with breast cancer; it is one of the more methodologically rigorous long-term epidemiological studies of environmental exposures and women’s health. Citing the peer-reviewed NCI study is different from citing press releases or news reports about the litigation, and it is important for potential claimants to understand that the science is ongoing and contested — defendants dispute both the methodology and the causal conclusions.
Researchers have identified several chemicals commonly found in hair relaxers as potential contributors to the observed risk, including phthalates, parabens, and formaldehyde-releasing preservatives. These chemicals are classified as endocrine disruptors, meaning they may interfere with hormone regulation in ways that could affect uterine and ovarian tissue.
FDA Action on Formaldehyde in Hair Products
In 2023, the U.S. Food and Drug Administration issued a proposed rule to ban formaldehyde and formaldehyde-releasing chemicals in hair smoothing and straightening products. The FDA noted that formaldehyde is a known carcinogen and that products releasing formaldehyde vapor during use expose consumers and salon workers to levels of concern. The proposed rule does not constitute a finding of legal liability, but it is relevant context for the litigation because it reflects a regulatory agency’s formal risk assessment of chemicals present in many of the products at issue.

Who May Qualify to File a Claim
Eligibility questions in mass tort litigation are fact-specific, and no attorney can responsibly guarantee qualification without reviewing an individual’s history. That said, the profile of potential claimants described in the MDL filings generally involves the following questions:
Women who used chemical hair relaxers or straightening products regularly — particularly over multiple years — and who were later diagnosed with uterine cancer, uterine fibroids, or ovarian cancer may qualify to file a claim. Regular use is typically characterized in the litigation as frequent application over an extended period rather than occasional use.
Additional factors attorneys typically evaluate include: the specific products used and the manufacturers involved; the timing between product use and diagnosis; the claimant’s medical records and treatment history; and whether the applicable statute of limitations has run. Because the MDL involves defendants from multiple states, choice-of-law questions can affect which limitations period applies to an individual claim.
No settlement fund, compensation grid, or payout amount has been publicly established in MDL 3060 as of this writing. Any source promising specific recovery amounts should be viewed with caution. This is an active litigation, and outcomes remain uncertain.
What to Do If You Think You Have a Claim
If you used chemical hair relaxers regularly and have since been diagnosed with uterine cancer, uterine fibroids, or ovarian cancer, the most important step is to speak with a personal injury attorney who handles mass tort cases before assuming you do or do not qualify. Attorneys evaluating these claims typically review product use history, medical records, and the timeline of diagnosis as part of an initial case assessment.
Preserve any records you have about the products you used, including receipts, photos, or brand names you remember. Gather your medical records relating to your diagnosis and treatment. These materials will be important to any attorney reviewing your potential claim.
Statutes of limitations in personal injury and product liability cases vary by state and by the nature of the claim. Waiting too long to consult an attorney can result in losing the right to file a claim, even if your case would otherwise be strong. Given that MDL 3060 is actively proceeding, claimants who believe they may qualify should seek a consultation promptly.
