Are you scrunching your hair with paper towels after you've applied product to wet hair? I think most Devachan Curl Consultants do that method, and I know it definitely helps me with drying time and curl formation. Also, have you tried plopping? If not, you'll have no problem finding threads about it. It also helps speed up the drying time for me, and I do it after I've scrunched with the paper towels, for about 15 minutes, then I diffuse. My hair is to the middle of my back and even after doing all of the above it still takes time to dry, but if I didn't do any of those steps, it would be several hours before it dried (unless I went productless).
