A recent study found no link between hair dyes and multiple myeloma. The National Institute of Health, the University at Albany, and Yale University collaborated to conduct the study published in the Occupational and Environmental Medicine journal.

In the past, studies discovered correlations between the use of hair dyes with an elevated risk of cancers like lymphomas and leukemia, possibly due to hair dyes from before 1980 that may have been formulated with suspected carcinogens.

For this study, researchers interviewed 175 women diagnosed with multiple myeloma and 679 cancer-free women.

Hair dye users were divided into four different groups: all dye users, semi-permanent dye users, permanent dye users, and dark permanent dye users. Dark permanent dyes were the most frequently used.

According to the results, there was no link between each category and multiple myeloma. Additionally, the researchers found that there was no correlation between myeloma and those who used hair dye before age 30; those who started using dye before 1980; those who had more than 240 applications; and those who had used dark permanent dye for 28 or more years.

While this study shows that there is no link between hair dyes and developing myeloma, further studies still need to be conducted involving a larger sample size. Additionally, the correlation between the use of hair dyes and the development of other cancers should be studied.
