Hair Care Products PFAS 'Forever Chemical' Contamination Litigation
Case Overview
Following independent laboratory testing published in 2022 that detected per- and polyfluoroalkyl substances (PFAS) in dozens of popular hair care products — including shampoos, conditioners, dry shampoos, and leave-in treatments — a wave of class action lawsuits was filed against manufacturers including L'Oréal, Revlon, Strength of Nature, and several store-brand producers. PFAS are a class of thousands of synthetic chemicals used in manufacturing for their non-stick and water-resistant properties; they are called "forever chemicals" because they do not break down in the human body or environment. Chronic exposure has been linked by the EPA and peer-reviewed research to kidney and testicular cancer, thyroid disease, immune suppression, and reproductive harm.
The lawsuits allege that defendants knew or should have known their products contained PFAS, failed to disclose this contamination on product labels, and marketed the products as safe for regular use — constituting consumer fraud, breach of warranty, and negligence under state and federal law. Plaintiffs include consumers who purchased and used the products as directed, as well as individuals who developed PFAS-associated health conditions following long-term use. Several cases have been coordinated in the Northern District of Illinois, with discovery ongoing as of 2025. The litigation parallels broader PFAS mass tort actions targeting manufacturers like 3M and DuPont in other product categories.
Who May Qualify
Individuals in the United States who purchased or regularly used hair care products (shampoos, conditioners, styling treatments, or dry shampoos) from the named defendants that have been identified as containing PFAS, particularly those who used such products for an extended period and/or have been diagnosed with a PFAS-related health condition such as kidney cancer, thyroid disease, or immune disorders.
