There are a few nice co-wash choices at Sally's Beauty Supply, if that's an option for you. Both As I Am and Eden Body Works have much less expensive cleansing conditioners than Deva No-Poo. I know there's a thread here comparing Yes To Carrots to One C, but I think that's the DevaCURL One C. My closest comparison to DevaCARE One C would be Regis Olive Oil Conditioner- I get mine from the salon inside WalMart- it's about $17.50 for a liter bottle, which is less than half the price of Deva.
