Hair Relaxer Lawsuit — Chemical Straightener & Cancer Claims
Chemical hair relaxers and straighteners contain endocrine-disrupting chemicals linked to serious women’s health conditions, especially uterine cancer. Lawyers from Trial Lawyers United represent women diagnosed with uterine cancer, ovarian cancer, and other conditions after regular use of chemical hair relaxers.
What Are Chemical Hair Relaxers and Straighteners?
Chemical hair relaxers and straighteners are cosmetic products designed to permanently alter hair texture by breaking and reforming chemical bonds within the hair shaft. The active ingredients include:
- Sodium hydroxide (lye): Highly alkaline chemical that disrupts hair protein structure.
- Calcium hydroxide: Alternative to lye in ‘no-lye’ products.
- Other potentially harmful ingredients: Phthalates, parabens, and other endocrine-disrupting chemicals that penetrate the scalp.
These products have been widely marketed and used, particularly within Black communities, where cultural norms and economic access have driven high consumption.
The NIH/NIEHS Sister Study: Major Evidence of Cancer Risk
In 2022, the National Institutes of Health (NIH) and National Institute of Environmental Health Sciences (NIEHS) published a landmark study in the Journal of the National Cancer Institute based on the Sister Study cohort of over 33,000 women:
- Hair relaxer use was associated with a significantly elevated risk of uterine cancer.
- Frequent use (≥4 times per year) was associated with a 3.6-fold increased risk of uterine cancer.
- Risk was dose- and duration-dependent: longer cumulative use meant higher risk.
- The association was particularly strong in Black women.
This study provided the first robust epidemiological evidence of a major cancer risk from chemical hair relaxers.
Other Health Conditions Associated with Hair Relaxer Use
- Ovarian cancer: Elevated risk due to similar endocrine-disrupting mechanisms.
- Endometriosis: Chronic inflammatory condition affecting the endometrium.
- Uterine fibroids: Benign but symptomatic growths.
- Premature menopause: Earlier-than-expected ovarian failure.
- Fertility impairment: Difficulty conceiving or maintaining pregnancy.
Mechanism: Endocrine Disruption
Chemical hair relaxers contain compounds that mimic or interfere with human hormones. Key mechanisms include:
- Estrogen mimicry: Some ingredients bind to estrogen receptors in reproductive tissues.
- Scalp penetration: Repeated application allows chemicals to penetrate the skin barrier and enter systemic circulation.
- Cumulative exposure: Each application adds to the body burden of endocrine-disrupting chemicals.
- Window of vulnerability: Adolescent and young-adult use may establish patterns of high-dose exposure during critical developmental periods.
Who May Qualify for a Hair Relaxer Claim?
- Women who regularly used chemical hair relaxers or straighteners for extended periods (typically 5+ years of frequent use).
- Diagnosis of uterine cancer, ovarian cancer, or other recognized hair-relaxer-related condition.
- Medical records documenting cancer diagnosis and treatment.
- Evidence of product use: purchase records, salon records, or testimony about frequency and duration.
- Women of all races may have claims; Black women have disproportionate exposure and documented elevated risk.
Defendants in Hair Relaxer Litigation
Major defendants include:
- L’Oreal (including subsidiaries and brands under its portfolio).
- Revlon (personal care products including hair relaxers).
- Namaste Laboratories (SoftSheen-Carson brand, historically marketed to Black women).
- Other manufacturers of chemical relaxer and straightener products.
MDL 3060: Hair Relaxer Litigation in Northern Illinois
Hair relaxer-related cancer claims have been consolidated into Multi-District Litigation (MDL) No. 3060 in the U.S. District Court for the Northern District of Illinois.
Disproportionate Impact on Black Women
The hair relaxer market has historically targeted and marketed heavily to Black women. Consequently:
- Black women have the highest average frequency and duration of hair relaxer use.
- The Sister Study found the strongest cancer associations in Black women.
- This reflects both marketing patterns and cultural factors surrounding hair in American society.
- Environmental injustice: Products marketed to Black communities carry disproportionate health risks.
Frequently Asked Questions
I used hair relaxers for many years but no longer do. Can I file a claim?
Yes, if you have been diagnosed with uterine cancer, ovarian cancer, or another recognized condition. The statute of limitations begins when you discovered (or reasonably should have discovered) the link between your product use and diagnosis.
What if I cannot remember exact dates or brands of products I used?
We understand that many women used hair relaxers over decades and may not have precise records. We accept testimony and reconstructed exposure history based on frequency and duration recollection. Medical and salon records, if available, provide additional documentation.
How do manufacturers defend hair relaxer claims?
Defendants typically argue that the NIH study is not sufficient to prove individual causation, that confounding factors (obesity, reproductive history, hormone replacement therapy) explain cancer risk, or that warnings were present. We counter these arguments with expert testimony and individual medical evidence.
What compensation might I recover?
Recovery includes medical expenses (past and future), lost income, pain and suffering, and in cases of advanced disease or shortened life expectancy, substantial damages. We estimate each case individually based on cancer stage, prognosis, and impact on quality of life.
Uterine or ovarian cancer diagnosed after hair relaxer use?

In the Relentless Pursuit of Justice | Results Without Risk
The mass tort litigation described on this website is based on publicly available information about ongoing legal proceedings. Case status, MDL rulings, settlement programs, and qualification criteria are subject to change. The information on this page is current as of the date indicated and may not reflect the most recent developments in the litigation.
Filing a case inquiry or contacting our office does not guarantee that you have a viable claim. All potential claims are subject to individual evaluation, including a review of your exposure history, medical records, and the applicable statute of limitations in your state.
Statute of Limitations Warning
Time limits apply. Every state sets its own deadline for filing a personal injury or mass tort claim. These deadlines, known as statutes of limitations, vary by state, by the type of claim, and by individual circumstances such as the date of diagnosis or discovery of the injury. Failing to file within the applicable deadline may permanently bar your right to seek compensation. If you believe you have a claim, contact an attorney promptly to determine the filing deadline that applies to your situation.
No Guarantee of MDL or Class Participation
References to multidistrict litigation (MDL), class actions, or coordinated proceedings on this website do not guarantee that your individual case will be filed in or accepted into any particular proceeding. Case placement depends on jurisdiction, venue rules, and the procedures established by the presiding court.
Trial Lawyers United LLC handles personal injury and mass tort cases on a contingency fee basis. This means you pay no attorney fees unless and until we obtain a recovery on your behalf. If there is no recovery, there is no attorney fee. Contingency fees are calculated as a percentage of the gross recovery. In most cases, the client is also responsible for litigation costs and expenses, which may include court filing fees, expert witness fees, deposition costs, medical record retrieval, investigation expenses, travel, and other costs necessarily incurred in the prosecution of the case. These costs may be advanced by the firm during the pendency of the case and are typically deducted from the gross recovery in addition to the attorney fee. The specific percentage and the method by which expenses are calculated (whether deducted before or after the contingency fee is computed) will be set forth in the written fee agreement between the client and the firm, which must be signed before representation begins.
"No Fee Unless We Win" Qualifier
When we say "no fee unless we win," we mean that you will not be charged attorney fees if we do not recover compensation on your behalf. Litigation costs and expenses are separate from attorney fees and are addressed in the written fee agreement.
