According to new research, it has been found that women who regularly use hair dye are likely to be exposed to an increased risk of bladder cancer.
Dr Manuel Gago-Dominoguez, a researcher conducted a series of studies on bladder patients and healthy women, all of the same age. The research showed a link between bladder cancer and hair dye.
The investigators found that women who used permanent hair dye at least once in a month were twice as likely to develop bladder cancer, as women who did not use permanent hair dye.
Dr Manuela Gago-Dominguez said: 'Our novel observations are provocative and carry enormous public health implications’.
'Yet it is a little premature to make any recommendation about stopping the use of permanent hair dyes.'
'However, this is one of the largest and most comprehensive studies ever conducted on the issue and we think our results should not be ignored.'
Even some hairstylist and barbers are 50 percent more likely to have bladder cancer than those who did not experience occupational exposure.
But according to Dr John Corbett, a consultant to the Cosmetic, Toiletry and Fragrance Association, Dr Gago-Dominguez and her team may have used a faulty study design.
'Their measure of exposure is just frequency of use and duration of use, which is not very good,' said Dr Corbett.
He added: 'The most important factor in exposure to hair dye is the shade you use’.
'All of the shades use essentially the same chemicals, but there is quite a lot more of them (the chemicals) in dark brown and black than there are in blonde'.
