While some women find their gray hair distinguished, others want to pluck every gray they see. While I personally think gray hair looks classy on a lady, I can understand why some women want to color over it.
The bad news is that hair dye has been connected to bladder cancer. In one large study, women who used permanent hair dye at least once a month were twice as likely to develop bladder cancer as those who did not. And those women who regularly used hair dye for at least 15 years had triple the risk. The chemicals in hair dyes can penetrate the skin on your scalp, enter your bloodstream, and get filtered out through your kidneys into your urine and bladder. The lining of the bladder is a very sensitive mucous membrane, and regularly exposing this membrane to the potential carcinogens in hair dye can lead to cell damage that can eventually develops into cancer.
To reduce your risk, dont use permanent, dark colored hair dyes, which have more of the offending chemicals. Instead, consider trying other options, such as henna, semi-permanent dyes, highlights, and herb-based rinses. Some salons, like Aveda, offer dyes that have lower concentrations of certain chemicals like peroxide and ammonia. I also suggest you try foiling, as less of the dye touches your scalp.
