Chemical Hair Relaxer Lawsuits: Holding Manufacturers Accountable for Cancer Risk

Home » medical devices » other defective products » chemical hair relaxer lawsuits

Thousands of women across the country are now taking legal action against companies like L’Oréal, Revlon, and SoftSheen-Carson for injuries they believe were caused by toxic chemicals in these widely used products. If you’ve been diagnosed with uterine, ovarian, or endometrial cancer after years of using chemical hair relaxers, you may have the right to pursue compensation from the manufacturers who failed to warn you about the risks.

At Ferrer Poirot Feller, we’re fighting for women who trusted these products and were never told they might be dangerous. For decades, chemical hair relaxers and straighteners were marketed as safe, even though mounting research suggested a link between their use and serious reproductive cancers.

You shouldn’t have to face a cancer diagnosis alone, or pay the price for a manufacturer’s failure to protect you. Our attorneys are here to help you understand your legal rights, explain how the litigation process works, and fight to hold these companies accountable.

The Link Between Chemical Hair Relaxers and Cancer

Chemical hair relaxers work by breaking down the protein structure of hair to create a permanently straightened texture. To achieve this, these products contain harsh chemicals—including formaldehyde, formaldehyde-releasing agents, parabens, phthalates, and other endocrine-disrupting compounds. Many of these substances have been linked to hormonal imbalances and reproductive harm.

In October 2022, the National Institutes of Health published findings from the Sister Study, a large-scale research project tracking the health of more than 33,000 women. The study found that women who used chemical hair straighteners more than four times a year had more than double the risk of developing uterine cancer compared to women who never used these products. The risk was especially pronounced among Black women, who reported higher rates of frequent use.

This research followed years of smaller studies suggesting similar concerns. Scientists have long known that many chemicals in hair relaxers act as hormone disruptors, mimicking estrogen and potentially contributing to cancer development in hormone-sensitive tissues like the uterus, ovaries, and breasts.

Despite this growing body of evidence, manufacturers continued to market these products without adequate warnings. Women were never told that the very products they trusted to help them manage their hair might increase their cancer risk. That failure to warn is now the foundation of thousands of lawsuits filed across the country.

What Cancers and Conditions Are Alleged in Hair Relaxer Lawsuits?

Lawsuits currently filed in the hair relaxer litigation allege a range of serious reproductive health conditions. The most common diagnoses include:

• Uterine cancer (endometrial cancer), the primary focus of the NIH Sister Study and the condition most frequently cited in legal claims
• Ovarian cancer, another hormone-related malignancy linked to endocrine-disrupting chemicals found in relaxers
• Endometrial hyperplasia, a precancerous thickening of the uterine lining that often requires surgery or leads to cancer
• Uterine fibroids, noncancerous growths that can cause severe pain, bleeding, and fertility problems
• Breast cancer, which some claimants allege is linked to long-term exposure to hormone-disrupting chemicals in hair products

Each of these conditions has caused physical pain, emotional trauma, and financial hardship for the women affected. Many have undergone hysterectomies, chemotherapy, radiation, or other invasive treatments. Some have lost the ability to have children. Others have faced life-threatening illness or the loss of a loved one.

If you’ve been diagnosed with any of these conditions and used chemical hair relaxers regularly, you may have a valid legal claim. We’re here to help you understand your options.

Where Are Federal Cases Consolidated and Who Is the Judge?

Because thousands of individual lawsuits were filed in federal courts across the country, the U.S. Judicial Panel on Multidistrict Litigation consolidated these cases into a single proceeding for pretrial coordination. This type of consolidation, known as a multidistrict litigation (MDL), allows for more efficient discovery, expert testimony, and case management.

The hair relaxer cases are consolidated in MDL 3060 in the Northern District of Illinois under Judge Mary Rowland. As of early 2025, more than 10,000 cases have been filed in the MDL, with new cases being added regularly.

What Is an MDL?

MDL 3060 is not a class action. Each plaintiff maintains an individual claim with unique medical histories, product usage patterns, and damages. However, pretrial proceedings, such as document production, expert depositions, and legal arguments, are handled collectively to streamline the process and reduce costs.

Bellwether trials, which serve as test cases to gauge how juries might respond to the evidence, are expected to begin in the coming months. These early trials will help both sides understand the strength of the claims and may lead to settlement negotiations.

What’s the Science Behind the Claims?

The scientific foundation for hair relaxer lawsuits rests primarily on the NIH Sister Study and decades of research into the health effects of chemical exposure. The Sister Study, published in the Journal of the National Cancer Institute, followed tens of thousands of women for years and documented their use of hair products alongside their cancer diagnoses.

The results were striking. Women who used chemical straighteners more than four times per year had a 2.5 times higher risk of uterine cancer. The study controlled for other risk factors like obesity, smoking, and family history, and the association remained significant.

Other research has pointed to specific chemicals commonly found in relaxers, particularly formaldehyde and formaldehyde-releasing agents like methylene glycol, as potential carcinogens. The American Cancer Society and the International Agency for Research on Cancer have classified formaldehyde as a human carcinogen, meaning it is known to cause cancer.

Parabens and phthalates, also common in hair relaxers, are classified as endocrine disruptors. These chemicals can interfere with hormone production and regulation, potentially increasing the risk of hormone-sensitive cancers like those affecting the uterus, ovaries, and breasts.

While manufacturers have challenged the science and argued that correlation does not prove causation, the weight of the evidence continues to grow. Independent researchers, public health experts, and federal agencies have all raised concerns about the safety of these products.

Did the FDA Ban These Products?

The FDA has not yet banned chemical hair relaxers, but it has taken steps toward regulation. In 2023, the FDA proposed a rule that would ban the use of formaldehyde and formaldehyde-releasing chemicals in hair straightening and smoothing products. The proposal cited health risks, including cancer and respiratory harm.

If finalized, this rule would represent a significant shift in how these products are regulated in the United States. However, as of early 2025, the rule remains under review, and products containing these chemicals continue to be sold on the market.

The fact that the FDA is moving toward a ban strengthens the argument that manufacturers knew, or should have known, about the risks these chemicals posed. For years, advocacy groups and researchers called for stricter regulation, but manufacturers continued to sell these products without clear warnings.

Do You Qualify for a Hair Relaxer Uterine Cancer Lawsuit?

You don’t need to have every detail figured out before contacting a lawyer. You just need to know that something went wrong and that it might be connected to the products you used. You may have a valid claim if:

• You were diagnosed with uterine, ovarian, endometrial, or breast cancer, or with severe uterine fibroids
• You used chemical hair relaxers or straighteners regularly for several years, whether at home or in a salon
• You used products from brands like L’Oréal, Revlon, SoftSheen-Carson, Strength of Nature, or similar manufacturers
• Your diagnosis occurred after prolonged exposure to these products
• You have medical records confirming your diagnosis and treatment

You don’t need to have receipts for every product you purchased. You don’t need to remember the exact brand or formulation. What matters is that you used these products consistently and developed a qualifying condition.

At Ferrer Poirot Feller, we’ll work with you to piece together your product use history, gather your medical records, and determine whether you have a strong case. Call us at (214) 521-4412 for a free case evaluation. We’ll listen to your story, answer your questions, and explain what happens next.

What Compensation Is Available in a Hair Relaxer Lawsuit?

If you’ve been harmed by chemical hair relaxers, you may be entitled to compensation for the physical, emotional, and financial toll these products have taken on your life. Every case is different, but damages in hair relaxer lawsuits may include:

• Medical expenses, including surgery, chemotherapy, radiation, hospital stays, and ongoing treatment
• Future medical care, such as follow-up screenings, reconstructive surgery, or fertility treatments
• Lost income, if you were unable to work during treatment or recovery
• Pain and suffering, reflecting the physical pain and emotional trauma you’ve endured
• Loss of quality of life, including the inability to have children, permanent health complications, or loss of bodily function
• Wrongful death damages, if you lost a loved one to cancer caused by these products

The value of your case depends on the severity of your diagnosis, the extent of your treatment, and how the illness has affected your life.
