Considering that the widespread utilization of hair dye goods, even a small increase in threat can possess a considerable public health impact.
Over time, several epidemiologic (population) studies have found an increased chance of bladder cancer from hair dressers and barbers (two, 6). An account by the International Agency for Research on Cancer (IARC) concluded that a few of the chemicals these employees are vulnerable to occupationally are"likely carcinogenic to humans". |}

The pooled analysis contained 4,461 girls with NHL and 5,799 females who didn't possess NHL. The outcome of the analysis demonstrated that girls who commenced making use of hair dye earlier 1980 had a marginally (30%) greater risk of NHL compared with females who hadn't ever used hair dye, while no such increase in risk was seen for girls who commenced making use of hair dye after 1980.

For the large part, the gains were confined by girls who commenced making use of hair dye previously 1980, although an greater chance of follicular lymphoma was observed in girls who started utilizing dark-coloured dyes immediately after 1980. Although these outcomes are in agreement with the idea that previous hair dyes were carcinogenic, it is likewise possible that the lack of increased hazards for hair dye people who began making use of dyes after 1980 reveals lower accumulative exposure levels or inadequate period since first exposure for virtually any growth in risk to become evident.
