Hair Relaxer & Ovarian Cancer: What Plaintiffs Must Prove
Over the past several years, thousands of women have stepped forward alleging that chemical hair relaxer products caused them to develop ovarian cancer, uterine cancer, or other reproductive health conditions. These lawsuits are being consolidated into emerging mass torts across the U.S., with plaintiffs arguing that manufacturers failed to warn of the risks.
For attorneys handling these cases, success hinges on demonstrating causation, negligence, and damages — and leveraging expert medical-legal support to build strong claims.
The Link Between Hair Relaxers and Cancer
Hair relaxers often contain endocrine-disrupting chemicals such as:
Phthalates
Formaldehyde-releasing agents
Other hormone-altering compounds
Studies have shown that repeated, long-term use of chemical relaxers may increase the risk of ovarian and uterine cancers by disrupting hormonal balance and damaging reproductive tissues.
While the science is still developing, the lawsuits claim that manufacturers knew or should have known of these risks and failed to provide adequate warnings.
What Plaintiffs Must Prove
To succeed in a mass tort claim, plaintiffs and their attorneys generally need to prove:
Exposure – The plaintiff used chemical hair relaxers regularly over time.
Causation – Medical evidence supports that these products significantly increased cancer risk.
Negligence/Failure to Warn – Manufacturers failed to disclose known or foreseeable risks.
Damages – The plaintiff suffered ovarian cancer or related conditions, leading to medical costs, lost income, and pain and suffering.
Because these are mass torts, plaintiffs do not need to prove their case in isolation. Instead, cases are consolidated, and shared scientific and medical evidence is used to support claims across hundreds or thousands of plaintiffs.
Challenges in Hair Relaxer Cancer Litigation
These cases are complex because:
Ovarian cancer has multiple risk factors (genetics, environment, lifestyle).
Symptoms may appear years after exposure, complicating timelines.
Defense teams argue there is no conclusive causal link.
That’s why expert documentation, medical records review, and chronology building are critical.
