Cancer and Chemical Hair Relaxers: What You Need to Know

Chemical hair relaxers are a popular way to straighten and smooth textured hair. Nevertheless, a mounting concern revolves around the potential connection between hair devices and cancer. Scientists are continuing their efforts to comprehend precisely how these devices might contribute to an elevated risk of cancer.

The research on the use of these hair products and the diseases they can cause is still in its early stages. More research is needed to confirm the link and identify the specific chemicals responsible. In the article, we explore cancer and chemical hair relaxers, offering research insights and safer hair care alternatives.

Chemical Hair Relaxers: How They Work

Hair relaxers transform curly hair into smooth locks, a popular choice for managing natural hair textures with remarkable results. The Hair Relaxer Market is expected to grow to USD 1103.9 million by 2032, with a 3.4% CAGR. In 2022, it stood at USD 796.8 million, as reported by MarketResearch.Biz. This market thrives as a dynamic and ever-growing industry, enticing a broad audience with its widespread popularity.

Chemical hair relaxers operate by disrupting the disulfide bonds within the hair cortex. These disulfide bonds are robust chemical connections responsible for shaping and texturing the hair. When these bonds are disrupted, the hair shaft can become straightened.

These relaxers are primarily categorized as lye relaxers and no-lye relaxers. Lye-based relaxers incorporate sodium hydroxide, a potent alkaline substance capable of causing harm to both the hair and the scalp. No-lye relaxers include milder ingredients like guanidine hydroxide or calcium hydroxide.

Regardless of the type of relaxer employed, the procedure remains fundamentally unchanged. The relaxer is evenly applied to the hair and allowed to sit for a typically recommended duration of 15-30 minutes. During this period, the chemicals within the relaxer effectively dismantle the disulfide bonds within the hair.

The Cancer Concerns

The relationship between hair devices and potential diseases has become a topic of considerable concern and debate in recent years. There are several reasons why these products may increase cancer risk. One reason is that they contain harmful chemicals. Hair straighteners often contain formaldehyde, a known carcinogen. 

Formaldehyde can be absorbed through the scalp and into the bloodstream, where it can damage DNA and lead to illnesses.

Another reason is that chemical hair relaxers can disrupt hormone levels. Hormones are influential in numerous physiological functions, encompassing cell growth and division. When there’s an imbalance in hormone levels, it can result in the proliferation of detrimental cells.

In recent years, several studies have linked its regular use to an elevated risk of specific cancer types among women. According to TorHoerman Law, they have been linked to an increased risk of cancer of uterine, breast, and ovarian. It is a cause for concern, especially for women, who are likelier to use these devices than other women.

The risk of hair straightener cancer appears to be higher for Black women as they use it more frequently and for longer periods. Scientists are researching hair straighteners and linked diseases, particularly the role of formaldehyde, a common ingredient in these products. They are striving to comprehend the precise mechanisms behind the potential health risk.

Research and Scientific Studies

The concerns related to the potential link between hair devices and health issues have spurred extensive scientific research. These investigations aim to uncover the risks associated with these products and have illuminated various aspects of this complex issue. As a result, we’ve gained essential insights into the safety implications of hair products.

Scientific investigations have aimed to identify specific chemicals present in these products that may pose a risk. Formaldehyde, used in some of these products, has been a focus of concern. This chemical has been classified as a carcinogen by reputable health agencies, highlighting the need for safer alternatives in hair care.

In 2022, a noteworthy study in the Journal of the National Cancer Institute investigated hair dyes, straighteners, and uterine cancer risk. The study, involving 33,947 women, revealed a higher likelihood of the disease among regular chemical hair straightener users. It underscores the need to evaluate the health implications of hair-altering products.

Health Risks and Safety Precautions

These hair devices come with potential health risks. They can lead to scalp irritation and burns if not used correctly, weakening the hair and causing hair loss and damage. Additionally, some individuals may experience allergic reactions to the chemicals, resulting in symptoms like hives, swelling, and breathing difficulties. It’s essential to be aware of these risks when considering chemical hair relaxers.

The potential health risks associated with hair appliances have raised important questions about the safety of these products. These potential risks can be classified into short-term and long-term health risks. As research delves into the link between these appliances and health issues, it’s vital to prioritize user safety precautions.

One of the key safety measures is proper ventilation during the application process. The New York Times reported that inhaling formaldehyde may worsen asthma, causing coughing and wheezing. The FDA’s proposed rule mentions the risk of respiratory issues. Exposure to formaldehyde may result in stinging eyes and nose, along with skin irritation.

Also, it’s advisable to conduct a patch test before using any hair relaxer to check for potential allergic reactions. Always follow the manufacturer’s instructions carefully and avoid overuse or excessive exposure to these products.

Regulatory Oversight and Consumer Information

The Food and Drug Administration (FDA) in the United States oversees the regulation of chemical hair relaxers. Nevertheless, the extent of the FDA’s control over these products is restricted. For example, the FDA does not require manufacturers to test these products for safety before they are marketed.

Calls for increased FDA oversight of such appliances have gained momentum. This push is amplified by mounting research into the potential connection between these products and health risks. Nevertheless, the FDA has not taken substantial measures to confront these concerns.

Consumers are entitled to be informed about the potential hazards linked to hair devices. Yet, there is currently no mandate for manufacturers to include this information on product labels.

Alternatives to Chemical Relaxers

With rising concerns about health risks, it’s vital to consider safer alternatives for achieving straight, manageable hair. Fortunately, several options can help individuals maintain their desired look without resorting to potentially harmful chemicals.

One effective alternative is using heat-styling tools like flat irons or straighteners. While these devices may temporarily straighten hair, they do not involve chemical ingredients and, when used correctly, can minimize damage. Natural methods like blow-drying with a round brush or braiding offer the desired hair-straightening effect without risks.

Final Words

The convergence of beauty and health requires meticulous consideration, particularly concerning chemical hair relaxers and their potential risks. Given the ongoing research and debate on the potential link between these products and cancer, prioritizing safety and informed choices is essential.

When dealing with hair products, the top priority is one’s health. With the right knowledge, preventive measures, and informed choices, it is possible to achieve the look you desire while prioritizing your well-being. As science continues to untie the complexities of this issue, a balance between beauty and health remains the ultimate goal.
