British scientists have recently discovered that some hair dyes used by millions of women have chemicals in them that have been linked to cancer. It does not matter whether you buy a hair dying kit yourself from the store or have it done at an expensive salon; when the dye comes in contact with tobacco smoke or other air pollutants it has the ability to become toxic.
Researchers say that one-third of women dye their hair and so do one in ten men. It was not difficult for researchers from the Leeds-based company, Green Chemicals, to discover this connection. They researched the chemicals in the hair dye and just by doing that they were able to determine the potentially fatal connections.
“They warn that chemicals called secondary amines, which are either found in all permanent hair dyes or are formed in them, can penetrate the skin and stay on the hair for weeks, months or even years after the dye is applied.
Over time, they could react with tobacco smoke and exhaust fumes, to form highly poisonous chemicals called N-nitrosamines.
Unsafe: Even dyes used at expensive salons can contain the dangerous chemicals
Known to cause cancer, these are banned from use in cosmetics.
But the Leeds researchers argue that they can still be generated via a simple chemical reaction.
Hair dye has previously been linked to a range of cancers, including tumours of the breast, bladder, ovaries and brain and leukaemia.
There are also concerns that increasing numbers of people are becoming allergic to their contents, sometimes with fatal results.”
