Hair dye could cause cancer

Women who regularly use permanent hair dye may be putting themselves at increased risk of bladder cancer, new research findings suggest. The study is the first to show that how often you use hair dyes affects your bladder cancer risk.

The investigators found that women who used permanent hair dye at least once a month were twice as likely to develop bladder cancer, as women who did not use permanent hair dye.

Those who reported regular use of the hair dye for at least 15 years were more than three times as likely to develop bladder cancer as non-dye users, concluded the study.

Even some hairstylists and barbers were 50 per cent more likely to have bladder cancer than those who did not experience occupational exposure.
