Across the nation, thousands of women are now seeking justice from the hair relaxer lawsuit, which is an evolving legal action that charges cosmetic manufacturers with failing to adequately warn consumers of the grievous health risks associated with chemical hair straighteners. At the Law Office of Cohen & Jaffe – Long Island Personal Injury Lawyers, we are actively engaged in following these developments and helping New Yorkers understand what this means for those who used hair relaxer products and who subsequently suffered from reproductive cancers or related medical conditions.
Hair Relaxer Lawsuit: What You Should Know
The hair relaxer lawsuit has been centralized under Multidistrict Litigation (MDL No. 3060) in the Northern District of Illinois after plaintiffs across multiple federal courts filed similar claims. According to the U.S. Judicial Panel on Multidistrict Litigation (JPML), these actions share common questions of fact about whether chemical hair-straightening products containing phthalates and other endocrine-disrupting chemicals caused uterine, ovarian, or breast cancers, endometriosis, and other reproductive injuries. The Panel determined that consolidation would promote efficient, consistent handling of discovery and pretrial proceedings against major manufacturers, including L’Oréal and Revlon.
The Hidden Risks of Hair Relaxers
For decades, hair relaxers have been marketed as safe, beauty-enhancing products, often targeting women seeking smoother, straighter hair. However, many of these formulas contain chemicals that penetrate the scalp and may enter the bloodstream. Frequent or long-term use can lead to chronic exposure to EDCs—compounds known to disrupt hormone function and increase the risk of certain cancers.
Users have reported additional complications such as burns, scalp irritation, and damage to hair follicles. Yet the more alarming concern lies beneath the surface, where hormonal disruptions may develop over years before symptoms appear. Many consumers had no idea they were using products capable of altering hormonal and reproductive systems until recent studies brought the issue to light.
Cancers Related to Hair Relaxers
Emerging research has linked chemical hair relaxer products to several forms of cancer affecting the reproductive system. The most concerning connection is to uterine cancer, where women who frequently used chemical straighteners were found to face more than twice the risk compared to those who did not. Ongoing investigations have also associated long-term relaxer use with ovarian and breast cancers, as well as conditions such as endometriosis and uterine fibroids, all believed to stem from exposure to endocrine-disrupting chemicals that interfere with hormonal balance.
Who Are the Defendants in the Hair Relaxer Cancer Lawsuit?
The hair relaxer lawsuit targets some of the largest beauty and cosmetic corporations in the world. Named defendants include L’Oréal, Revlon, and Strength of Nature. These companies are accused of negligence, failure to warn, and fraudulent marketing. Plaintiffs allege that the defendants continued to sell and promote these chemical products—often marketed to women of color—despite having access to research and internal testing that suggested potential health hazards.

Hair Relaxer Lawsuit: Allegations and Evidence
A 2022 National Institutes of Health (NIH) study found that women who used chemical hair straightening products faced a higher risk of developing uterine cancer than those who did not use these products. The research, part of the Sister Study of 33,497 U.S. women ages 35 to 74, followed participants for nearly 11 years and identified 378 uterine cancer cases. Women who reported using straighteners more than four times in the previous year were at a higher risk to later develop uterine cancer compared to non-users. The study estimated that 1.64% of women who never used straighteners would develop uterine cancer by age 70, compared to 4.05% of frequent users.
Hair Relaxer Alternatives to Avoid Health Complications
As the hair relaxer lawsuit highlights, many chemical straighteners contain harmful ingredients linked to hormonal and reproductive health issues. To reduce risk, avoid products containing:
- Formaldehyde or formaldehyde-releasing agents.
- Phthalates (like DEHP)
- Parabens
- Sodium hydroxide (lye) or guanidine hydroxide (no-lye relaxers).
- Triclosan
These substances may cause endocrine disruption, skin damage, or increased cancer risk. Review product labels carefully and follow FDA updates on formaldehyde regulation.
