Hair dye could cause cancer - and brunettes are at greater risk

Ladies who regularly use permanent hair dye might be putting themselves at elevated chance of bladder cancer, new information findings suggest.

The research is the first one to reveal that how frequently you utilize hair dyes affects your bladder cancer risk.

Investigator Dr Manuela Gago-Dominguez has carried out a number of studies on bladder patients and healthy women - all the same age - and located a hyperlink between bladder cancer and hair dye.

Within the latest research Dr Gago-Dominguez, from the College of Los Angeles Med school in La, and her co-workers analysed 897 installments of bladder cancer where details about hair dye use was available.

They in comparison these patients having a similar quantity of grown ups who didn't use permanent hair dye.

The researchers discovered that ladies who used permanent hair dye at least one time per month were two times as prone to develop bladder cancer, as ladies who didn't use permanent hair dye.

They required smoking cigarettes - a recognized risk factor for bladder cancer - into account within their information.

The research findings is going to be released within the Feb problem from the Worldwide Journal of Cancer.

Dr Manuela Gago-Dominguez stated: 'Our novel findings are provocative and carry enormous public health implications.

'Yet it's a little premature to create any recommendation about preventing using permanent hair dyes.'

'However, this is among the biggest and many comprehensive studies ever carried out around the problem so we think our results shouldn't be overlooked.'

Individuals who reported regular utilisation of the hair dye not less than fifteen years were greater than three occasions as prone to develop bladder cancer as non-dye customers, came to the conclusion the research.

Even some hairstylists and barbers were 50 percent more prone to have bladder cancer than individuals who didn't experience work exposure.

But based on Dr John Corbett, an advisor towards the Cosmetic, Toiletry and Scent Association, Dr Gago-Dominguez and her team might have used a faulty study design.

'Their way of measuring exposure is simply frequency of usage and amount of use, that is not so good,' stated Dr Corbett.

He added: 'The the very first thing in contact with hair dye may be the shade you utilize.

'All from the shades use basically exactly the same chemicals, there is however quite a bit much more of them (the harmful chemicals) in brownish and black than you will find in blonde.'

Also, Corbett suggests the scientists 'seem to create light of previous studies' through the National Cancer Institute and also the American Cancer Society that unsuccessful to locate a similar association between hair dye use and cancer risk.

He stated: 'The final point here is I do not think (the brand new study findings) should affect individuals their decision whether to make use of hair colour or modify the hair colour industry in thinking about they sell safe items.'
