I'm not sure if you have heard about Samy Pure hair care products. I am recently going organic with shampoo and conditioner (because regular ones test on animals and have harsh chemicals :S). Samy Pure hair products have natural ingredients, are sulfate free-no harsh chemicals, contain no wax or residue (it's not surprising how many shampoos have that), and are 100% vegan with no animal by-products. It's also INEXPENSIVE :D :), and you don't have to spend a lot of money on it like most natural shampoos and hair products. You can find Samy Pure products from your local drugstore. I've passed by them at the store a lot and have been putting some thought into trying it.
