Blackcat, you look like a wavy
I am a wavy/curly and we wavies don't get a lot of bounce. Period. Some of us have hair with curls which spring back 2, 3, even 4 inches on a humid summer day.
A good cut will help (for example, layers which take the weight off the hair underneath). Using a diffuser to press the hair towards the scalp helps (plopping does too if that works for you). Lots of wavies do both! The weight of the water can pull your wave pattern out.
Protein treatments also help boost waves and curls, especially for us low-porosity types.
Curl-enhancers are a good bet. My favorites in no special order are Kiss my Face Upper Management, Lily of the Desert Aloe 80, FSG (with extra goodies added. These all have polysaccharides which are not only humectants, but also polymers -- trapping moisture (especially if used under another gel) and providing a little more hold. There are other curl enhancers too.
Come introduce yourself to the wavy (2s) board, we're a friendly and resourceful bunch and I think you'll find lots of helpful information!
