I'm not sure I even have a good/decent routine. I use a non-sulfate shampoo starting at the scalp and rinsing away build up. Then One-Condition starting at tips and working up. I tried Deva No-Poo but found build up at my back scalp to be horrible. The only product to ever work on my hair, best in the front 3a part, is TIGI Curls Rock. I've tried a number of others but nothing has quite worked the same way. I haven't tried a leave-in conditioner as I don't really know the process, but a stylist recommended using a baby towel to scrunch my hair to get the water out without frizzing the curls.
