2023 Hair Relaxer Lawsuit Update

Following recent studies that link hair relaxers and cancer side effects, a growing number of women are now pursuing hair relaxer lawsuits over the manufacturer’s failure to warn about the toxic side effects of undisclosed chemicals used in hair straightening products.

  • Consumers began filing hair relaxer lawsuits after a new study was published in October 2022, which found that women who used hair relaxers more than 4 times per year faced significantly increased risks of developing uterine cancer.
  • The first hair relaxer uterine cancer lawsuits were brought in early November 2022, claiming manufacturers failed to warn that endocrine disrupting chemicals used in the products could amplify cancer cell growth in female reproductive organs.
  • As women continue to learn about the side effects caused by hair relaxers, the litigation is expected to grow significantly throughout 2023.
  • Lawyers are actively investigating new cases for women who have suffered injuries from exposure to toxic chemicals in hair relaxer products.

Latest Updates on Hair Relaxer Lawsuit: January 2023

January 23, 2023 Update: The U.S. JPML will hold oral arguments (PDF) at the Wilkie D. Ferguson, Jr. U.S. Courthouse in Miami, Florida on January 23, 2023, to decide whether an MDL should be created for hair relaxer lawsuits filed throughout the federal court system.

December 2022 Update: Several manufactures including L’Oréal, Dabur, House of Cheatham and Strength of Nature filed responses with the U.S. JPML on December 7, 2022, opposing centralization of the growing number of hair relaxer lawsuits being filed over uterine cancer, ovarian cancer and uterine fibroids. While each manufacturer raised arguments against centralizing the hair relaxer cases in to one multidistrict litigation, it is expected that the U.S. JPML will establish a hair relaxer MDL, since thousands of lawsuits are expected to be filed in the coming months and years.

November 2022 Update: With at least nine hair relaxer lawsuits already pending in the federal court system, a group of plaintiffs filed a motion (PDF) with the U.S. Judicial Panel on Multidistrict Litigation (JPML) this month, calling for all hair relaxer lawsuits to be centralized before a U.S. District Judge in Illinois for coordinated discovery and pretrial proceedings.

Can Hair Relaxer Cause Cancer?

In recent years multiple studies have been published that suggest a possible link between hair relaxers and cancer risks, including uterine cancer, ovarian cancer and hormone disorders. Researchers have warned many hair relaxer products contain as many as 5,000 chemicals, many of which are classified as toxic, including, but not limited to;

  • Formaldehyde
  • Phthalates
  • Di-2-ethylhexylphthalate (DEHP)
  • Cyclosiloxanes
  • Bisphenol A
  • Parabens
  • Other harmful toxins and volatile organic compounds (VOCs)

The U.S. Food and Drug Administration (FDA) sets forth laws under the Federal Food Drug and Cosmetic Act that expressly prohibits the marketing or sale of cosmetic products from containing poisonous or harmful substances that could cause injury to a consumer. However, many cosmetic manufacturers mislabel their hair relaxer or omit these toxins from the ingredients labels, withholding important safety information from consumers..

2022 Study: Hair Relaxers Increase Uterine Cancer Risks

A study performed by researchers from the National Institute of Environmental Health Sciences (NIEHS) was published in the Journal of the National Cancer Institute in October 2022, warning that ingredients used in hair relaxers may cause uterine cancer

NIEHS researchers reviewed data on nearly 34,000 women in the United States between the ages of 35 and 74 who completed questionnaires on their use of multiple hair products, including hair dyes, straighteners, relaxers, or pressing products.

A 10 year follow-up on the incident rate of uterine cancer diagnosis was performed, finding participants who used straightening products at least once had the highest rate of uterine cancer diagnosis compared to any other hair products involved in the study.

The study revealed women who routinely used hair relaxer chemical products were nearly 3x more likely to have developed uterine cancer by the age of 70 when compared to women who never used chemical relaxer products.

Hair Relaxer Uterine Cancer Rates

African American women frequently using hair relaxer products had the highest rate of developing uterine cancer, making up only 7.4% of study participants, but accounted for 59.9% of those reporting use of the chemical relaxers.

2019 Study: Hair Relaxers Increase Breast Cancer Risk by 30%

Another study performed by researchers at the National Institute of Environmental Health Sciences (NIEHS) was published in the International Journal of Cancer (IJC) in 2019, indicating women using straightening products for their hair face a significantly increased risk of developing breast cancer.

Researchers collected data from the Sister Study, which is a long-term research project pioneered by the U.S. Department of Health and Human Services, which involves over 50,000 participants to study how the environment and genes affect women’s chances of getting breast cancer.

Over an eight year period, researchers reported that women who used hair relaxers at least every five to eight weeks, had a 30% increased risk of developing breast cancer. African American women who reported using permanent hair dyes regularly were associated with a 60% increase of breast cancer diagnosis, compared to an 8% increased risk for Caucasian women.

2017 Study: African American Women Hair Relaxers Breast Cancer Risks

A study performed by researchers from the Rutgers Cancer Institute was published in the medical journal Carcinogenesis in 2017, finding the use of chemical straighteners and hair relaxers increased breast cancer risks by 74% among white women. The authors concluded the study stating;

“These novel findings provide support a relationship between the use of some hair products and breast cancer,” and “Further examinations of hair products as important exposures contributing to breast cancer carcinogenesis are necessary”

Based on the currently available science we are not moving forward with breast cancer claims at this time.

Based on the currently available science, the lawyers at Saiontz & Kirk, P.A. are not currently pursuing hair relaxer breast cancer lawsuits.
