If you have a Trader Joe's near you, their store brand shampoos are great (and about $2 a bottle!). They are also cone and sulfate free. The Refresh is better for oily hair (too drying for me, but it's great on my five-year-old when she needs a wash. We normally do CO on her, but she's five. She gets paint or mud in her hair from time to time.) I use the Nourish shampoo. More moisturizing than the Refresh.
