From Frizz to Fears: Understanding the Potential Cancer Risks of Chemically Hair Straightening

From Frizz to Fears: Understanding the Potential Cancer Risks of Chemically Hair Straightening

Step into the captivating world of hair products, where innovation and style go hand in hand. As we navigate through the vast realm of hair care, we stumble upon a pressing question that demands our attention: what are the true effects of chemically straightening our beloved tresses? Brace yourselves for an eye-opening revelation, as we uncover the untold truth behind this intriguing mystery. Join us on a journey that will both educate and entertain, as we delve into the fascinating details and shed light on the potential risks involved in hair straightening treatments.

What is Chemically Straightening Hair?

 Chemically straightening hair is a popular cosmetic procedure that involves using chemical products to make the hair straight. One common method is the "keratin treatment" or "Brazilian blowout," which typically includes a solution containing formaldehyde or a formaldehyde-releasing compound.


Formaldehyde is a colorless gas with a pungent odor and has been classified as a human carcinogen by regulatory agencies like the International Agency for Research on Cancer (IARC). There are concerns about the potential cancer risks associated with formaldehyde-based products used in hair straightening treatments.


Exposure to formaldehyde can occur during the application of the treatment when the product is heated or when the hair is blow-dried or flat-ironed. The heat can cause formaldehyde to vaporise, and inhalation of formaldehyde has been linked to respiratory and eye irritation, allergic reactions, and an increased risk of cancer.

It's important to note that the misconception that chemically straightened hair causes cancer likely emerged because formaldehyde has been associated with certain types of cancer in industrial settings with prolonged and significant exposure. However, the concentration of formaldehyde used in most commercial hair straightening products is regulated to be within safe limits in many countries.

Studies have examined the relationship between formaldehyde exposure from hair straightening products and cancer risk. The National Toxicology Program (NTP) conducted a study in 2011 and found that high concentrations of formaldehyde used in unventilated areas can induce cancer in animals. However, the levels of formaldehyde used in these studies exceeded those typically found in salon environments.

Epidemiological studies have also investigated the association between formaldehyde exposure and cancer risk in humans. A 2012 study focused on hairdressers and barbers found an increased risk of certain cancers with higher levels of formaldehyde exposure. However, these findings were based on occupational exposure levels and not solely related to hair straightening products.

A December 2022 study published in the Journal of the National Cancer Institute reported a positive link between the use of straightening products and uterine cancer. However, further research is needed to validate these findings in different populations, identify specific chemical ingredients involved, and evaluate their impact on health disparities related to uterine cancer. The study suggests that targeting the use of hair straighteners could be a potential intervention to reduce the incidence of uterine cancer.

Overall, while there are concerns about the potential health risks associated with the use of formaldehyde-containing hair straightening products, the concentrations typically found in commercial products are regulated to be within safe limits. It's important for individuals to be aware of the potential risks and make informed choices regarding hair straightening treatments.

Regulatory Measures and Consumer Safety

Hair straightening regulations can be a bit like a choose-your-own-adventure book, varying from country to country and subject to change. In the New Zealand, the responsible parties for overseeing these regulations are the New Zealand Medicines and Medical Devices Safety Authority (Medsafe) and the Environmental Protection Authority (EPA). They're the ones making sure our hair straightening journeys are as safe as can be.

To keep our hair out of harm's way, strict limits and restrictions are set on harmful substances, like a protective shield for our locks. Clear labeling, instructions, and safety precautions are a must, so we know what we're getting into and how to keep our hair happy and healthy. If you've ever had a hair-raising experience, you can report it through the Adverse Event Reporting system, like sending a signal for help from the hair safety headquarters.

Good Manufacturing Practices (GMP) are in place to ensure consistent and reliable manufacturing, so you can trust that your hair straightening products are made with love and care, just like your hair deserves.

Now, let's talk tips to minimise your encounters with any unwanted hair drama:

  1. Do your research: Before diving into the world of hair straightening, take a moment to research the ingredients. Look for products that proudly claim to be formaldehyde-free.

  2. Give labels a read: Don't let those labels feel left out. Take a moment to read the labels on hair straightening products.

  3. Consult a professional stylist: When in doubt, seek the wisdom of a professional stylist. They can be your hair's trusty guide, helping you navigate the world of formaldehyde-free alternatives and pointing you towards safer options.

  4. Embrace natural methods: Sometimes, the best solutions are the simplest. Embrace your hair's natural beauty by trying out natural methods for managing and styling. Let your hair air-dry, give heatless styling tools a whirl, or rock hairstyles that celebrate your hair's unique texture.
