So I don't know if this is an obvious question, but something I'm still confused about. I totally agree about cutting out things like parabens and SLS. I just purchased Burt's Bees shampoo and conditioner, and my hair honestly looks great. If I were to switch to no 'poo, would I see a huge difference in my hair? Is even natural shampoo like Burt's bees going to be putting harmful ingredients into my hair?
