I forgot to mention that I buy a lot of products from a company called Moo Goo, which is a small cottage industry here in Australia (started up in WA moved to QLD I think) that is committed to healthy hair and skin products that are as chemical free as possible. They make an excellent baby scalp cream and a lovely shampoo. On their web site they go into great detail about how most chemicals like SLS affect you. They are very committed to making the safest products possible and most are safe enough to drink, but they admit they would taste disgusting LOL
