I have been having the same problem with moisture. I think I've fixed mine now. I read on Live Curly Live Free that hair that feels dry may actually need more protein. So, I upped my protein treatments to every week for a while. That seemed to help. My hair doesn't like oil to seal, so I started putting the Shea Moisture Curl and Syle milk, which has some oils, over my conditioner that I leave in...just a nickel size. That really helped. I also plop my hair, and that helps with the volume. Hope this helps.
