Long term hair dyes, which produce up about 80% of currently marketed items, include of colourless dye"intermediates" (compounds called aromatic amines) and dye"couplers." |} In the existence of hydrogen peroxide, the intermediates and also couplers respond with one another to sort pigment molecules.

It's not known whether some of these compounds still used in hair dyes can bring about cancer. Given the wide spread utilization of hair dye merchandise, a small increase in threat can possess a large public health influence.
Over the years, some epidemiologic (population) studies have found that an greater probability of bladder cancer in hair dressers and barbers (two, 6). A report by the International Agency for Research on Cancer (IARC) concluded that a few of the compounds these staff are exposed to occupationally are"possibly carcinogenic to humans". |}

Because the small size of several studies might have restricted their capacity to detect an association between hair dye use and cancer, a pooled (joint ) investigation of 4 case control studies have been carried out (8). All studies had obtained detailed information regarding hair dye use, including dates and duration of use, and NHL sub type. The pooled analysis included 4,461 females with NHL and also 5,799 ladies who failed to possess NHL. The outcome of the analysis revealed that females who commenced employing hair dye earlier 1980 had a slightly (30 percent ) improved risk of NHL in comparison with ladies who had never applied hair dye, while no such increase in risk was found for ladies who commenced employing hair dye later 1980.
Once the researchers analyzed the hazards of several special NHL sub types , they found that hair dye end users had increased probabilities of both follicular lymphoma and chronic lymphocytic leukaemia/small lymphocytic lymphoma. For the large part, the gains were confined to ladies who commenced employing hair dye previously 1980, but an heightened probability of follicular lymphoma was observed among females who began employing dark-coloured dyes immediately after 1980. Even though these outcomes are consistent with the idea the hair dyes are somewhat significantly more carcinogenic, it is likewise possible the absence of increased pitfalls for hair dye people who began employing dyes later 1980 reflects lower cumulative vulnerability ranges or insufficient time because first vulnerability for any growth in hazard to become evident.
What is the evidence that hair dye use is associated with chance of leukaemia?
Research of the association between hair dye use as well as the probability of leukaemia have experienced contradictory outcomes. For example, one case control analysis analyzed hair dye use one of 769 individuals with adult acute leukaemia and also 623 folks with no leukaemia in the USA and Canada (9).
