According to this piece most of the ingredients in shampoo are ‘a veritable toxic dump on your head’ and then the shampoo that ends up in our water supply causes male fish to grow ovaries. Eeeek!

What’s really in your shampoo by Bill Bunn in Salon.

Some shampoo sounds more like chicken marinade than shampoo, boasting of vitamins, minerals, protein and herbs. But, the vitamins and minerals and exotic extras play a useless role. So whether the shampoo brags that it is “infused” with real beer, exotic proteins, vitamins, antioxidants, or extracts from some fabulously endangered species, the additive saturates the users’ minds, not their hair.

All these ingredients would go bad were it not for preservatives, a chemical equivalent of the right to bear arms. Sodium benzoate, for example, is handy because it kills nearly every living thing that might start to grow in a shampoo bottle. Ironically, in most cases the detergents won’t go bad. It’s the psychological ingredients that need preservation.

And I was just crowing about having found a solution to frizziness: avocado shampoo, avocado conditioner, avocado treatment wax, anything avocado. True, Jay-Lo our hair theorist had recommended the actual fruit: cut in half, apply to hair, wash off. But it’s so much easier to buy a bottle of something sweet-smelling.
