Are hair dyes good for you? See health concerns

The World Health Organization (WHO) and the American Cancer Society (ACS) have both examined the potential health risks associated with hair dyes. While hair dyes are fashionable and trendy, it’s also important to check if they can impede your health with continuous usage.

The International Agency for Research on Cancer (IARC), a part of WHO, has evaluated various chemicals used in hair dyes. In their assessments, certain aromatic amines and organic dyes have been classified based on their carcinogenic potential. As an example, some industrial dyestuffs like CI Direct Blue 15 and CI Acid Red 114 were classified as possibly carcinogenic to humans. This means that there is a possibility of causing cancer to humans.

Additionally, IARC has reviewed occupational exposures of hairdressers and barbers, as well as personal use of hair colourants, to assess carcinogenic hazards.

The America Cancer Society (ACS) has explored the relationship between hair dye use and cancer risk. While many studies have investigated this potential link, the results have been mixed. Some research suggests a possible association between long-term use of dark-coloured permanent hair dyes and an increased risk of certain cancers, such as non-Hodgkin lymphoma and leukemia. However, other studies have not found a significant connection.

Furthermore, a study from the National Institutes of Health (NIH) indicated that women who used permanent hair dye and chemical hair straighteners had a higher risk of breast cancer compared to those who didn’t use these products.

In sum, while there is some evidence suggesting potential health risks associated with certain hair dye ingredients, findings are not conclusive.

It’s advisable for individuals to stay informed about the latest research and consider taking precautions, such as conducting patch tests and following product instructions, when using hair dyes or just avoid it all together.
