In the past year I've weaned myself to washing twice a week and now I'm ready for no poo!

I just purchased the Deva Curl "Low Poo" and "Condition One." After washing and allowing my hair to air dry, my roots felt and looked really greasy, which is abnormal for me. I tried the Low Poo again the next night, made sure I rinsed really well but it didn't make any difference. Now I'm having a bit of a freak out because my hair looks gross, but I don't want to give it up without a fight -- what could the problem be?

My current gel has silicone in it -- I see that many advise to dump the silicones because they cause build up but I don't put it near my roots. Could this still account for my problem? I also see that a lot of people advise to clarify before going No Poo. I'm going to try that tonight and see if that is the ticket (unless my shampoo also contains silicones, grrrr)
