What Do People Say About Their Experience with Hair Dye and Cancer?

My clients who have used hair dye products over their life talk about using these products insistently and regularly and never knowing that any of the chemicals in those products could cause cancer. These people went their local stores, they picked up the product that they were comfortable with, we picked up the product that was advertised to them and marketed to them to be something they could use regularly and safely. They never knew that the products contained chemicals that would ultimately cause them cancer.
