Ever since going mod-CG over just over a fornight ago, my hair seems to be getting less and less curly...

It feels softer, finer, and generally more healthy, but what used to be 2b/3a is now barely even wavy!

I use Naked Bounce shampoo and conditioner, which have no sulphates/cones in them (I couldn't go totally CG due to how bad my scalp got...). I then scrunch in L'Oreal's Studio Line Curl Power mousse (no cones), plop for about half an hour, and then leave to air dry.

What is going wrong, how can I get my curls back?
