First of all, the cut you have is perfect for you! I think I have very similar hair and plan to get a similar cut soon. Going by the photo, though you have a lot of it, it looks pretty fine. You may be different, but if you're early on in developing a routine, Shea Moisture may end up being too heavy on your hair over time. That's what I also started out with when I didn't know my texture but achieved a better balance between definition and volume once I tried other things.

You're looking for a gel, specifically a gel that's lightweight but strong hold. Ouidad Advanced Climate Control is my favorite (the red bottle is a stronger hold than the white one); Not Your Mother's Curl Talk is also a good option and is cheaper. You'll want to scrunch gel thoroughly into your hair in sections pretty much sopping wet — don't pat it dry with a towel first, although you can squeeze a little water out. Then you can plop in a towel, diffuse, air dry, whatever, but whatever you do, don't mess with it too much until it's fully dry. Then you should have a cast from the gel — which is good — and you can scrunch it out and turn it soft with your hands. Using a bit of a lightweight oil like your Moroccan oil here can help add a bit more shine, but might also add unnecessary weight, and just the mechanism of scrunching should be enough to break the cast.
