Hair Relaxers Linked to Increased Cancer Risk: Thousands of Women Sue Manufacturers

Hair Relaxers and Uterine Cancer Risk

• 💡 A study published by the National Institute of Health (NIH) in October 2022, known as the sister study, followed nearly 34,000 women for almost 11 years.
• 🎯 Women who used chemical hair relaxers more than four times per year were found to be more than twice as likely to develop uterine cancer compared to non-users.
• ⚠️ Critics noted that the study's duration and specificity regarding products were limited.

Black Women's Health Study Findings

• 🔬 Dr. Kimberly Bertrand's team at Boston University School of Medicine conducted a study on almost 45,000 Black women for over 20 years.
• 📈 Their findings, published in October 2023, indicated that postmenopausal women who used chemical hair relaxers for many years or frequently had about a 60% increased risk of developing uterine cancer.
• 📌 This research aimed to understand why uterine cancer disproportionately affects Black women, with chemical hair relaxers being a potential exposure.

Chemical Ingredients and Regulation

• 🧩 Studies dating back to 1997 have identified potential toxic chemicals in hair relaxers, such as parabens and phthalates, which are endocrine disruptors.
• ⚠️ Associations have also been found between chemical hair relaxer use and uterine fibroids, and modest associations for breast cancer.
• 🔍 A major criticism is the lack of specific ingredient naming, as product labels may simply state "fragrance" or "preservative," with the FDA not requiring detailed disclosure of fragrance ingredients.

Legal Battles and Lawsuits

• ⚖️ As women learned about the science, they began to sue hair relaxer companies.
• 🤝 A multi-district litigation (MDL) was formed in February 2023 in Illinois to consolidate over 50 lawsuits, now exceeding 9,800 cases by February 2024.
• 🏛️ The MDL allows for shared discovery and costs, making it a more feasible approach for individuals against large corporations like L'Oreal, which distributes products under the Soft Sheen Carson brand.

Manufacturer Response and Transparency

• 🗣️ L'Oreal stated that the health and well-being of customers is their highest priority and that their products undergo rigorous safety evaluations and adhere to regulations.
• 🧐 The company expressed confidence in the safety of Soft Sheen Carson products and believes the allegations lack legal and scientific merit, pointing to the initial study's call for further research.
• ✅ A key demand from plaintiffs and advocates is greater transparency on ingredient labels so women know what chemicals they are being exposed to.
