Dr. Mercola's Comments:
Hair color is often one of the few cosmetics that even “natural-minded” people justify using,
often to cover up gray hair. Some estimates even say that more than one in three women,
and one in 10 men over 40, throughout Europe, North America and Japan use some type of
hair color.
Clearly the risks of these chemicals are magnified among hairdressers because they use
them so frequently. But don’t mistake that to mean that coloring your hair once every four
to six weeks is safe.
Your scalp has a very rich blood supply that is more than capable of transporting the toxins
in hair dyes throughout your entire body.
However, the panel found that the evidence was inadequate to classify the carcinogenicity
of personal hair dye use.
