Hair Relaxer Uterine Cancer Lawsuit

Chemical Hair Relaxers and Straighteners

Hair relaxer or hair straightener is a lotion or cream that makes the hair straighten and lay flat. These products use chemicals that break down the hair strand, altering the texture and eliminated the natural curl.

The process of getting chemical hair relaxer applied (often called getting a “hair perm”) occurs at home or at the salon. It involves applying the straightener product to the scalp at the base of the hair. The product then “cooks” over a period of time, during which the chemical structure of the hair is altered. The process must typically be repeated every month as hair grows in.

Hair relaxers and chemical hair straighteners are very unhealthy. These products have lots of synthetic chemicals that are hormonally active and carcinogenic, such as phthalates. Phthalates are chemicals known to cause endocrine disruption. Instead of being listed as ingredients, these chemicals are often obscured behind labels such as “fragrance” or “perfume.”

Phthalates and EDCs in Hair Relaxer

Phthalates belong to a family of manmade chemicals that are especially harmful to human biology because they are endocrine-disrupting-chemicals (EDCs). The endocrine system controls the circulation and distribution of vital hormones, such as estrogen, throughout the body. In women, it is comprised of the ovaires, the pituitary gland, the thyroid, and the adrenal gland. EDCs interfere with the normal activity of the organs in the endocrine system.


Di-2- ethyl hexyl phthalate (“DEHP”) is a EDC phthalate chemical that is used in all hair relaxer products, even those labeled as “non-chemical.” The compound is used to make the cream or lotion stick to the scalp and absorb into the hair. DEHP is an EDC that is known to cause adverse disruption of the endocrine system. When absorbed into the body, DEHP breaks down into various metabolites that are very harmful.

Uterine cancer

Uterine cancer (cancer in which a tumor forms in the endometrial tissue of the uterus wall) is a common type of cancer with about 65,000 new cases diagnosed each year in the U.S. 4 out of every 100 cancer cases are uterine cancer and 12,500 women died from uterine cancer each year (2% of cancer-related deaths).

African American women are disproportionately impacted by uterine cancer and are several times more likely to develop uterine fibroids compared to other racial groups. The survival rate for uterine cancer is comparatively good at 81%, but here too Black women in the U.S. statistically have worse outcomes with the lowest survival rate of any group.

Chemical Hair Relaxer Causes Uterine Cancer

Over the last 10 years, a study by researchers at the US National Institutes of Health (NIH) called the “Sister Study” has focused on a possible connection between exposure to chemicals in hair relaxer products and uterine cancer. The results of this major NIH Sister Study, which included over 33,000 women, were published in October 2022 in the Journal of the National Cancer Institute and they were very significant.

The Sister Study found that women who used hair straightening products were almost twice as likely to develop uterine cancer than those who did not (after adjusting for other risk factors). Even more significantly, those women who had reported more frequent use of straighteners or relaxers (more than 4 times per year) were about 2½ times more likely to develop uterine cancer.

The results of the Sister Study were a major breakthrough and went a long way towards resolving the disparity in uterine cancer rates between Black women in the U.S. and other racial groups. Around 80% of Black women in the U.S. use hair relaxer, most on a regular basis. The Sister Study suggests that this use of chemical hair relaxer may explain why Black women get uterine cancer more often than others.

Hair Relaxer Lawsuits

The breakthrough findings of the Sister Study have generated the start of what is likely to be a large wave of hair relaxer lawsuits against the cosmetic companies that manufacture these products. The first hair relaxer lawsuit was filed in federal court in Chicago in October 2022. It was quickly followed by a dozen more hair relaxer lawsuits over the next weeks.

Nearly all of these early hair relaxer lawsuits have been uterine cancer cases. The plaintiffs in these cases claim that they developed uterine cancer from chronic use of chemical hair relaxers. Major cosmetic companies such as L’Oreal and Revlon have been named as defendants in these cases.

L’Oreal makes Dark & Lovely®, which is the most popular hair relaxer product on the market. Revlon makes a leading brand of professional hair relaxer used in salons. A host of other small companies that make hair relaxer products have also been named as defendants.

Potential Settlement Value of Hair Relaxer Uterine Cancer Cases

It is very premature to speculate on the potential settlement value of hair relaxer lawsuits involving uterine cancer. The scientific evidence in these cases is still developing and don’t known if it will be admissible in court. The settlement value estimate below is based on a number of very significant assumptions.

Based on the assumption that the causation evidence is valid, our attorneys estimate that hair relaxer lawsuits involving uterine cancer will have a settlement payout value of $300,000 to $1,750,000. Certain cases presenting compelling circumstances, such as a very young plaintiff, could have a much higher value.
