Millions of women use chemical hair relaxers regularly. New scientific research three years ago revealed that chronic exposure to the chemicals in hair relaxer products can cause uterine and ovarian cancer. This new evidence prompted a wave of lawsuits against the manufacturers of hair relaxer products by women claiming that they developed cancer as a result of using these products.
These cases are moving forward. The MDL judge has scheduled the first bellwether trial for early 2027. These trials are intended to help both sides gauge how juries might respond to the evidence and could influence settlement discussions…if there is not a global settlement before the first trial, as many, including our lawyers, suspect.

June 3, 2026 – Hair Relaxer MDL Case Count Keeps Growing
The hair relaxer MDL now has 11,723 pending cases, according to the June 1 JPML report. That is up from 11,526 pending cases in the May report.
This is not explosive growth, but it is steady growth at a point when the litigation is already deep into discovery. That tells you something. The television ad wave has slowed, but women are still coming forward, and the docket is still getting bigger.
The MDL now ranks among the largest active mass torts in the country. That matters because size creates pressure. Defendants can fight one case forever. Fighting more than 11,000 cases, while state court trials are also moving, is a different problem.
June 2, 2026 – Expert Motion Briefing Hits a Key Deadline
The Rule 702 expert fight is now front and center. Both sides have filed motions seeking to limit or exclude general causation experts, and opposition briefs were due June 2.
This is a critical stage of the litigation. General causation is the gateway issue. Plaintiffs need to show they have reliable expert testimony that chemical hair relaxers can cause the injuries alleged in these cases, including uterine cancer, ovarian cancer, endometrial cancer, and other hormone-related injuries.
Defendants are trying to narrow the science before the first bellwether trial ever happens. That is exactly what defendants do in large product liability cases. If they can weaken the expert proof, they can weaken the entire settlement value of the litigation. If plaintiffs’ experts survive largely intact, the cases move much closer to real trial pressure.
June 1, 2026 – Class Certification Fight Moves Forward
The class certification briefing is also moving forward. Defendants’ oppositions to plaintiffs’ class certification motion and supporting expert reports were due June 2. Plaintiffs’ reply papers and rebuttal expert reports are due later this summer.
This class action track is separate from the personal injury bellwether cases, but it still matters. Plaintiffs are seeking class treatment for medical monitoring claims, arguing that women exposed to chemical hair relaxers should have access to court-supervised monitoring because of the increased risk of serious disease.
The personal injury cases are still the heart of the litigation. But the medical monitoring class claims create another front for defendants to defend. The more fronts defendants have to fight on, the harder it becomes to control the litigation.
Hair Relaxers
Hair relaxers, also known as “hair perms” or “straighteners,” are predominantly used by African American women to achieve a flat hair appearance. The process of hair relaxing, or lanthionization, can be carried out either at home or at a salon. Typically, the product is applied to the hair’s base or root and left in place to undergo a “cooking” process. During this process, potent chemicals within the product target the hair’s natural protein structure, compelling it to flatten. Generally, retreatment is necessary every 4-8 weeks.
Hair relaxers often contain harsh chemicals like phthalates, which pose potential harm to the human body due to their classification as endocrine-disrupting chemicals (EDCs). EDCs can disrupt the normal functioning of the endocrine system, which is responsible for regulating hormones such as estrogen. Notably, these chemicals are frequently not listed as individual ingredients on the product label. Instead, they are often broadly categorized under terms like “fragrance” or “perfume.”
Chemicals in Hair Relaxers
Hair relaxer products contain many powerful chemicals. Di-2-ethylhexyl phthalate (“DEHP”) is a particularly harmful phthalate chemical that is found in hair relaxer products. It is used to make the product adhere to the scalp and absorb into the hair. DEHP is an EDC that is known to cause major disruption to the endocrine system and trigger hormonal imbalances.
This interference can lead to various reproductive and developmental issues, including infertility, cancer, and developmental abnormalities. Scientists have shown that DEHP acts as a mimic for the female hormone estrogen, contributing to hormonal imbalances.
In response to these health risks, numerous countries have implemented regulations to restrict the use of DEHP and other phthalates in consumer goods. For instance, the European Union has prohibited the use of DEHP in children’s toys, and the United States has imposed limitations on its inclusion in children’s products. However, the use of hair relaxers by children raises more serious concerns, as the direct application of these products with chemicals poses a more intimate exposure compared to playing with a toy, emphasizing the need for increased awareness and regulation.
NIH Study Links Hair Relaxer to Cancer
In October 2022, the results of a groundbreaking long-term study called the “Sister Study” were published. The Sister Study was conducted by a research team at the National Institutes of Health (NIH), and it included a group of over 50,000 women who participated in the study.
The Sister Study found that frequent use of chemical hair relaxers (over 4 times per year) over long periods increased the risk of uterine cancer by 150%. The results of the Sister Study were definitive proof that hair relaxer was linked to uterine cancer. Chronic exposure to the chemicals in hair straightener products has also been linked to increased risks of ovarian cancer and breast cancer, and other health conditions involving the female reproductive system, such as uterine fibroids and endometriosis.
Hair Relaxer Class Action Lawsuit
Almost as soon as the Sister Study was published with its findings linking chemical hair relaxers to cancer, women across the country began filing lawsuits. These are product liability claims against some of the biggest cosmetic companies in the world, including L’Oréal, Dabur, and Godrej. These companies manufacture well-known brands such as Dark & Lovely, Africa’s Best, Motions, and Just for Me—products that many women have used for most of their lives, often beginning in childhood.
In January 2023, the growing number of federal lawsuits led to the formation of a multidistrict litigation (MDL) in Chicago. This consolidated all of the hair relaxer cancer cases under one judge, making it easier to manage early discovery, streamline legal arguments, and prepare for bellwether trials that might shape the future of the litigation. There were fewer than 50 cases when the MDL was formed. By the end of the year, the number had ballooned to over 8,000.
That rapid growth was partly driven by women connecting the dots between long-term relaxer use and serious diagnoses like uterine or ovarian cancer. It was also helped along by a wave of legal advertising—some useful, some just noise, all of it impossible to miss.
The women filing these lawsuits say they used chemical relaxers regularly, month after month, often for years. Many were later diagnosed with reproductive cancers. Their claims are straightforward: these companies failed to warn them. They marketed the products as safe, never mentioned the potential risks, and continued selling them despite growing scientific concerns.
Now, in 2025, the litigation is entering a more serious phase. Discovery is well underway, expert reports are coming into focus, and the first trial dates are now officially scheduled. The initial bellwether trial is scheduled to begin on November 3, 2025, with a second to follow in February 2026. These trials will be the first real test of the plaintiffs’ claims in front of a jury, and their outcomes could shape the path toward settlement or set the stage for a much longer fight. For many of the women at the center of this litigation, it is not just about compensation. It is about accountability. It is about answers. And it is about forcing billion-dollar corporations to finally reckon with the harm caused by products they sold for decades without warning.
Hair Relaxer Lawsuit Timeline: Key Events & Developments
2019
Initial Scientific Studies on Hair Relaxers and Cancer Risk
In 2019, researchers began investigating the potential health risks associated with chemical hair relaxers, particularly their link to hormone-related cancers. A notable study published in the International Journal of Cancer found that women who frequently used permanent hair dyes and chemical straighteners had a higher risk of developing breast cancer, with the association being more pronounced among African American women.
The concern was pretty obvious. These products often contain endocrine-disrupting chemicals (EDCs), which can interfere with hormonal functions. Further research highlighted that hair products used predominantly by Black women, such as relaxers, may contain hazardous chemicals with endocrine-disrupting and carcinogenic properties, potentially contributing to health disparities.
October 2022
NIH Study Links Hair Relaxers to Uterine Cancer
A major National Institutes of Health (NIH) study is published in the Journal of the National Cancer Institute.
Findings indicate that women who frequently use hair relaxers have a 2.5 times higher risk of developing uterine cancer compared to non-users.

November 2025
Revlon’s Bid to Dismiss Call Cancer Lawsuits Fails
The MDL judge denies Revlon Inc.’s request to dismiss with prejudice all cancer-related claims in the hair relaxer multidistrict litigation (MDL) simply because some plaintiffs lacked a formal cancer diagnosis, ruling that permanently barring potential future claims was too severe. But the judge does dismiss with prejudice all cancer claims filed after the September 14, 2023 deadline and rules that plaintiffs who lacked a confirmed cancer diagnosis but filed before that date could dismiss without prejudice and refile within six months of a diagnosis.
2025 and Beyond
Possible Settlements and Trial Outcomes
The good news is that the bellwether trial dates are set. This is important because trial dates put real pressure on the defendants. The bad news? We have a good way to go. The trial dates in the MDL will not be until 2027. State court trials may come before that.
Predicted Settlement Value of Hair Relaxer Lawsuits
The hair relaxer lawsuits are likely to be resolved through a global settlement, in which the defendants agree to set aside a substantial sum of money for a settlement fund to compensate plaintiffs. In global settlements like this, individual plaintiffs are ranked into “tiers” for purposes of determining the amount of their settlement payout. Plaintiffs with strong claims are in the highest settlement tiers and get more money.
In the hair relaxer class action, uterine cancer cases are expected to fall within the highest settlement tier due to compelling scientific evidence establishing a causal link between hair relaxer use and uterine cancer (as demonstrated in the Sister Study). Additionally, uterine cancer is deemed a more serious injury when compared to uterine fibroids or endometriosis.
Our attorneys estimate that the settlement compensation for hair relaxer-related uterine cancer cases may range from $300,000 to $1,750,000. The wide range in this estimated value is due to the fact that individual uterine cancer cases may be valued differently based on specific circumstances surrounding each case. We think a successful ovarian cancer case could have an average settlement value of $150,000 to $450,000 if things go as planned. The value for ovarian cancer cases is lower because the causation evidence is not as strong.
Now let’s focus on the projected average per-person settlement amounts. Here is one guess of how it could pay out:
Projected Hair Relaxer Settlement Payouts by Injury Type
| Injury Type | Estimated Average Settlement Range | Tier Level | Notes |
|---|---|---|---|
| Uterine Cancer | $250,000 – $500,000 | Tier 1 (Highest) | Strongest causation evidence (Sister Study); most serious injury |
| Ovarian Cancer | $100,000 – $200,000 | Tier 2 | Moderate causation support; significant injury but less conclusive linkage |
| Uterine Fibroids | $5,000 – $75,000 | Tier 3 | Weaker causation; payout depends on surgical history and complications |
| Endometriosis | $2,500 – $40,000 | Tier 4 (Lowest) | Limited scientific support; typically non-life-threatening condition |
Remember the non-cancer cases are be pursued outside of the MDL, but our lawyers are still taking these claims. We are talking average here. You would expect claims that are much higher and much lower.
