i agree that knowing your hair properties is the first step. and i also agree with using different products in different spots on your head, or more where it seems to need more moisture/hold. i use the same on mine, but need to use more leave in around the front.

also, if you have 2b/3a hair, it is usually straight until it reaches a certain length, enough for the curl/wave to start. that is the sign of 3a hair. so, you can let your bangs grow a little more, maybe part them to side, or just keep treating them well. sometimes 3a hair can get some root curl once it has all the moisture it needs. not always, but worth a try.
also, are you making sure to scrunch your bangs before air drying?
