L’Oreal Hair Relaxer lawsuit

Amid recent developments, a series of lawsuits have surfaced, targeting hair product giants involved in the hair relaxer industry. These lawsuits allege the use of hazardous chemicals in their hair relaxer products, raising significant health concerns for consumers. The products, marketed as permanent solutions for straightening textured hair, are now under intense scrutiny for their potential risks to human health. Despite possessing knowledge of these potential dangers, companies have continued to market and sell these products, subjecting consumers to undue risk.

A groundbreaking study, carried out by distinguished researchers at the prestigious US National Institutes of Health (NIH), has recently come to light. This study reveals a disquieting link between chemical hair straighteners and relaxers and an escalated risk of uterine cancer. The NIH’s findings were published in the highly regarded Journal of the National Cancer Institute on October 17, 2022, sparking heightened concerns surrounding the safety of these hair relaxer products.

Chemicals Found in Hair Relaxer Products and Associated Injuries:

  • Nitrosamines
  • EDCs and Phthalates – linked to DNA damage and increased risks of breast, prostate, testicular, endometrial, and uterine cancer. They also interfere with hormone function, leading to early puberty and infertility.
  • Parabens and propylparaben – linked to heightened risks of breast and uterine cancer.
  • Glycolic acid and salicylic acids – associated with cervical cancer.
  • Sodium hydroxide, Ammonium thioglycolate, Guanidine carbonate, Dimethyl sulfoxide – linked to various cancers, including breast cancer, cervical cancer, and leukemia. These chemicals have also been connected to infertility, premature births, miscarriages, and birth defects.

  1. Increased Cancer Risk: Heightened risks of uterine, endometrial, breast, cervix, testicular, leukemia, and bladder cancer.
  2. Developmental and Reproductive Damage: Reports of uterine fibroids, cysts, and other reproductive issues.
