Frequent Hair Straightener Use Linked to Cancer Risks – Should You Be Worried?

Hair Straightener Use Linked to Cancer Risks

For many, hair straighteners are a styling staple. A recent NIH study demonstrates that frequent use of chemical hair straightening treatments may raise the risk of uterine cancer.

According to the study, daily usage of these items may raise the chance of having the condition. As per John Hopkins Medicine, the study tracked over 33,000 women for over 11 years. It discovered that people who used straightening products more than four times per year had a more than doubled risk of developing uterine cancer.

This news has left many wondering: is this a cause for serious worry, and what should you do if you rely on hair straighteners?

The Science Behind the Link

The link between hair straighteners and cancer is likely due to the chemicals they contain. Many straightening products contain endocrine disruptors such as formaldehyde, parabens, and phthalates.

These compounds can imitate hormones in the body, which may have an influence on hormone-sensitive tumors such as uterine cancer. For example, Healthline states that formaldehyde is a proven carcinogen that has been related to a variety of malignancies, including leukemia. While the specific processes are still being investigated, the NIH study reveals a strong link between regular usage and increased risk.

Lawsuits and Legal Concerns

The NIH study has sparked a wave of legal action against hair product manufacturers. TorHoerman Law notes that women who have developed uterine cancer after frequent straightener use are filing lawsuits. 

These claims allege that manufacturers failed to adequately warn consumers about the potential health risks. The hair straightener cancer lawsuit highlights the need for increased transparency from the beauty industry regarding the ingredients in their products. 

Additionally, stricter regulations on the use of these chemicals in hair products may be on the horizon. NBC News notes that the FDA recently proposed a ban on certain formaldehyde-based hair straightening products due to safety concerns.

Weighing the Risks

While the NIH study identified an association, it’s important to understand the context. Uterine cancer is a relatively rare cancer, with an overall lifetime risk of about 3%. The study also found that even frequent users still had a relatively low absolute risk. 

However, for those who use straighteners frequently and have other risk factors for uterine cancer, this information may be valuable. Factors like a family history of the disease or obesity can help individuals make informed decisions about their health. 

According to WebMD, the study also found that African-American women are at a higher risk of uterine cancer from chemical hair straighteners. This is because the usage of hair straighteners is more common among this demographic.

Considering Alternatives

If you’re concerned about the potential risks, there are several alternatives to consider. Look for hair straightening products formulated with natural ingredients. NewBeauty notes that you can also explore heat-styling tools that minimize heat damage, such as ceramic or tourmaline flat irons. 

Additionally, reducing the frequency of straightening sessions and using heat protectant spray can also help lower your exposure to potentially harmful chemicals. Consider talking to your hairstylist about alternative styling techniques that don’t require heat altogether.

Consulting a Healthcare Professional

Ultimately, the decision of whether to continue using hair straighteners is a personal one. If you are worried about your individual risk, you should speak with a healthcare expert.

They may go over your medical history, risk factors, and the most recent research to help you make an educated choice regarding your hair care routine. They can also advise you on how to minimize your exposure to harmful chemicals if you choose to continue using straighteners.


How do I avoid endocrine disruptors? 

Endocrine disruptors are chemicals that mimic hormones. To minimize exposure, choose fresh, organic produce when possible. Opt for glass or stainless steel containers over plastic for food storage. Look for fragrance-free personal care products and avoid harsh cleaners.

Are chemical hair straighteners safe? 

The safety of chemical straighteners is under question. A recent study linked frequent use to an increased risk of uterine cancer. The chemicals in these products may act as hormone disruptors. More research is needed, but consider reducing use or talking to your doctor.

What is the lawsuit against chemical hair straighteners?

Lawsuits are emerging against hair straightener manufacturers. Women with uterine cancer who used straighteners frequently allege the companies failed to warn about potential health risks. These lawsuits underscore the need for more transparency about product components and their possible impacts.

To summarize, while the link between hair straighteners and uterine cancer requires further investigation, the NIH study suggests a potential risk. Women with a family history of uterine cancer or other risk factors should consider this information when making decisions about hair care. 

Safer alternatives include natural hair products, heat-protective sprays, and reduced heat styling. If you are concerned, consult a doctor to discuss your individual risk and ways to minimize exposure to potentially harmful chemicals.
