the most centle 'shampoo' I know is Curl Junkie Daily Fix. But that is actually more a 'washing conditioner' (but it has some very light sulfates in it).
Best option is to co-wash your hair with a silicone free conditioner. You can find more about a shampoo-free method (also known as Curly Girl method or CG method) on this website.
