Chemical Hair Straighteners and Uterine Cancer: A Controversy

The use of hair straighteners has become a common practice for many people worldwide, but there are concerns about the safety of certain ingredients in these products. The usage of hair straighteners containing high amounts of formaldehyde has been linked to an elevated risk of uterine cancer in a new study done by the National Institutes of Health (NIH).

This has led to numerous lawsuits being filed against manufacturers of these products, claiming that they failed to warn consumers of the potential health risks. 

According to a 2022 article published in The Legal Examiner, the first hair straightener cancer claims were brought against L’OrĂ©al and other cosmetics producers in October. In 2023, more cases are projected to be filed. If you have gotten uterine cancer after using chemical hair straightening or relaxer treatments, you should contact a personal injury attorney.

In this article, we will explore the types of chemicals found in hair straighteners, the findings of the NIH study, and what steps you can take if you have been affected by the use of these products. The health and safety of consumers should always be a top priority, and it is crucial that we remain informed and vigilant in the face of potential risks.

Types of Chemicals in Hair Straighteners

Chemical hair straightening is a popular method to change the texture and appearance of hair. Heat and chemicals are used to break down the natural connections in hair, allowing the hair to be straightened. Disulfide, hydrogen, and salt bonds are three forms of these bonds.

Sodium hydroxide, sodium thioglycolate, ammonium thioglycolate, formaldehyde, cyclosiloxanes, diethanolamine, phthalates, parabens, benzophenone-3, and triclosan are among the chemicals found in hair straighteners.

According to research, cancer-causing chemicals in hair straighteners include phthalates, parabens, and a very toxic compound known as DEHP. Phthalates are widely found in personal care products and are used to soften polymers.

Parabens are used as preservatives in personal care products, including hair straighteners. DEHP is a common plasticizer used to soften PVC and is found in many personal care products, including hair straighteners.

Cancer and other health problems may result from exposure to these substances. Endocrine-disrupting chemicals, or EDCs, present in chemical hair straighteners have been linked to elevated cancer risk, according to research.

National Institutes of Health Study

The National Institutes of Health (NIH) carried out a study to look at the relationship between uterine cancer and hair straighteners. The study analyzed the chemical composition of various hair straightening products and found that they contained several hazardous chemicals, including formaldehyde, which is a known carcinogen. 

The study concluded that regular exposure to these chemicals could increase the risk of developing cancer, especially in women who use hair straighteners on a regular basis.

The 2022 study also found that women who used hair straighteners were more likely to experience menstrual irregularities and hormonal imbalances, which are both risk factors for developing uterine cancer. 

The NIH study provided valuable insights into the potential dangers of hair straighteners and how they can impact women’s health. The study highlights the need for more research on this topic and for stricter regulations on the chemicals used in hair straightening products.

Filing a Lawsuit

There are several steps involved in filing a hair straighteners uterine cancer lawsuit, and it is important to consider your options carefully before proceeding. First, you should consult with a lawyer who specializes in product liability cases and has experience handling cases involving hair straighteners and cancer.

However, if you believe that your use of hair straighteners has caused or contributed to your uterine cancer, a lawsuit may be the best way to seek compensation and hold the responsible party accountable.


In conclusion, the recent controversy surrounding chemical hair straighteners and the increased risk of cancer highlights the importance of thoroughly researching cosmetic products before use. 

While lawsuits against major cosmetic brands are still ongoing, it is crucial to be aware of the potential health risks associated with chemical hair straighteners and to seek alternative hair-care options if necessary. Consumers should also take note of the presence of harmful chemicals in personal care products and make informed choices to protect their health.
