I asked our Curly Chemist about the sulfate in Neutrogena Triple Moisture Cream Lather Shampoo (Sodium Trideceth Sulfate) & she told me it's a milder one than SLS & SLES. I've used this shampoo in the past & it is very gentle.

As for silicones & sulfate-free shampoos, check out the links in my signature line.
