CANADA: Hair dye use does not increase the risk of cancer, a comprehensive study co-authored by a Montreal-based researcher shows. The new analysis, published in the Journal of the American Medical Association, examined the results of 79 studies. It concluded that hair dye does not markedly increase the risk of cancer in its users.
The results don’t say there’s definitely no risk, said co-author Mahyar Etminan, a McGill University Health Centre researcher. “But it’s reassuring to know that when we pool all the data, we don’t really find an association.”
