Well...you can always try "pineappeling" your hair while it is wet, to achieve lift at the roots. I have similar hair to yours - once it dries, it stays! I use some strong hold gel at the roots, then I get a wide ribbon made of cloth (you could literally use anything for this, like a strip of t-shirt) and i flip my hair over, put the ribbon in near the roots, and allow to air dry. I prefer using a ribbon, because you can put in/remove without disturbing your curls.
You can do this process just at the beginning of drying, and when your hair is 75-80% dry, you can remove the ribbon and place your part, so that it will be in place but not flatten your hair. This should give you some sort of root lift
I use the ribbon to pineapple my hair while I sleep, and I also use this technique on second day hair, I just wet my hands with water and a drop of the strong hold gel, moisten my roots and re-ribbon it till it is dry to give me that root lift
I didn't like the clip system myself, as I found my hair would get tangled in the clips, and I would inevitably break some trying to get the clips out.
I also found the Deva products made my hair ridiculously limp and soft after about 4 times of using it, then my hair *really* reacted to the protein in it and I had to stop using their products
Anyways, good luck, and I hope this has helped! Remember, though, what works for one gal won't work for everyone

But you can always try this ribbon trick on a day where you won't be going to work, so you can test drive it...
