I've returned to using cones in moderation and I use a very mild shampoo which is specifically for colored hair, since I dye my hair and most important: I dilute the shampoo like ShubhoR does (earlier in this thread).
The poo contains sulfates but it is a gentle, moisturizing shampoo and diluting it makes it even gentler. I've tried Lo Poo and I just don't like the results as well; my scalp feels greasy afterward. Sometimes I will use Deva NoPoo and skip washing altogether and that's fine too, but I usually just use the shampoo for dyed hair.
You really need to experiment to make the decision about what works best for your hair. Have fun!

Stylers: Experimenting with cones & sulfates while the dews are high. Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
