Each time I visit the barber, I always dye my hair to keep away the grey hairs. I want to know how safe is this.

Some of the ingredients in hair dyes can cause serious allergic reactions in some people. Hair dyes can also cause hair loss in some people. Some doctors advise women to avoid having their hair dyed during pregnancy (or at least until after the first trimester) When hair dyes first came out, the main ingredient used in coal-tar dyes caused allergic reactions in some people. Most hair dyes now are made from petroleum sources. There have been some studies that have linked hair dyes with a higher risk of some cancers. Other studies, though, have not found these links. But keep in mind most hair dyes don’t have to go through the same safety testing that other cosmetic color additives do before they’re sold in stores. Cosmetic makers have stopped using compounds known to cause cancer in animals. But chemicals made almost the same way have replaced some of those cancer-causing agents. Some experts feel that these newer ingredients aren’t much different from the things they’re replacing. Health experts suggest that you may reduce your risk of cancer by using less hair dye over time or by not dyeing your hair until it starts to gray.
