Do you use hair color to highlight your locks, add a splash of hot pink or electric blue for fun, or change your look permanently? Many people do, and some wonder if it might affect their chances of getting cancer.

Some studies show a link between the chemicals in certain hair dyes and cancer. But they don’t prove that hair color was to blame. The risk is probably low in people who color their hair from time to time. If there is a risk, it’s probably higher for people who work with dye all day long, for darker colors, and for dyes that last longer.

Hair dyes made before 1980 contained some chemicals that were linked to cancer. Since then, companies have changed the chemicals they use to make their dyes. Yet there still may be a few ingredients in dyes that might be risky.
