Hidden Dangers: The Health Risks of Using Formaldehyde on Your Scalp

For decades, chemical hair relaxers have been a popular choice for achieving sleek, straight styles. However, many of these products contain formaldehyde or formaldehyde-releasing compounds. When heated during the straightening process, these chemicals release formaldehyde gas, which helps break and reshape the hair's natural keratin structure.

While effective for straightening, formaldehyde is a known human carcinogen, as classified by the International Agency for Research on Cancer (IARC). Exposure to formaldehyde in hair relaxers has been linked to various health risks. Salon professionals and clients alike may experience immediate reactions, including eye, nose, and throat irritation, breathing difficulties, and skin sensitivity.

More concerning, long-term exposure has been associated with serious conditions such as reproductive health issues and an increased risk of certain cancers. Research, including a study published in the Journal of the National Cancer Institute, has found correlations between frequent use of chemical hair straighteners and a higher incidence of hormone-sensitive cancers—particularly among women of color, who tend to use these products more regularly.

If you're concerned about the potential health impacts of chemical hair relaxers, consider exploring safer alternatives. According to the FDA:

"Hair smoothing products are used to straighten hair or to smooth out curls. A hair straightening or smoothing solution is usually applied to human hair followed by a heat treatment that seals the solution in. These products often contain formaldehyde, also known as formalin and methylene glycol. When the solution is heated, the formaldehyde in the products is released into the air as a gas. If the salon is not properly ventilated, both the salon professionals and their clients are at risk of inhaling the released formaldehyde."
