Gallery: Illegal Cancer-Causing Chemicals Found in Nearly 100 Well-Know...


You may have thought that the worst thing your shampoo could do to you is to sting your eyes, but it turns out that your shampoo could be deadly. The Center for Environmental Health based in Oakland, California, performed a study on shampoos and soaps and found that 98 included a possible carcinogen known as cocamide diethanolamine (cocamide DEA).

Cocamide DEA is a chemically modified form of coconut oil that is used as a thickener or foaming agent in shampoo. However, the state of California has outlawed its use, because it may be carcinogenic to humans. The CEH is suing companies producing and distributing these products, including Prell, Paul Mitchell and Colgate Palmolive shampoos. Also included are products marketed to children, and even one which falsely claims to be organic (Organic by Africa’s Best.)

Until things are resolved, it seems like getting shampoo in your eyes may have become the least of your concerns. You can find a full list of all 98 suspect shampoos here.

    It seems to be a daily occurrence that we are told there is some destructive chemical in something we use. For hair products the best I have found (smells amazing too) is Probiotic Shampoo and Conditioner from Air Thai Life. Not the cheapest out there but it is incredible. You can find her stuff at

    So what IS good, especially for fine, long, greying hair (trying to grow for “Locks-of-Love”) I rinse w/ Apple cider vinegar to “contract my hair ends” (from my hair care gal).
