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.
