Attorneys are investigating whether long-term use of chemical hair relaxers is linked to uterine, ovarian, and endometrial cancers, and whether manufacturers failed to adequately warn consumers about the chemical compounds in their products.
Women who used chemical hair relaxers regularly (more than four times per year) and were subsequently diagnosed with uterine, ovarian, or endometrial cancer. Both retail and salon-applied products are within the scope of the investigation.
A 2022 National Institutes of Health Sister Study found women who used chemical hair relaxers more than four times per year had more than double the risk of uterine cancer compared to non-users.
If enough affected individuals come forward and the facts support viable legal claims, a participating plaintiffs' firm may file a putative class action. Investigations may also be closed without a filing if attorneys conclude the case is not viable. Submitting your information does not commit you to anything.
