Sulfates in shampoos have become highly controversial. Sulfates are the ingredients in shampoo that cause the shampoo to lather. We've come to expect the better the shampoo lathers, the better the shampoo is, however some people disagree, claiming some people are allergic to sulfates.
Sulfates may very well be dangerous, too. Many natural health experts recommend avoiding any shampoos with the foaming agents sodium laureth sulfate and ammonium laureth sulfate as main ingredients. Laboratory studies show that products that end in "eth" such as sodium laureth sulphate, polyethylene glycol, oleth, myreth, ceteareth all test positive for 1,4-Dioxane, a proven cancer-causing petrochemical.
