Yeah, if I comb while wet my waves almost disappear (I say almost--the ends flip out no matter what!). I'm a 2b like you.
Now I only comb while soaking wet and producty, then scrunch like crazy. Usually, though, now that mine's shorter, I don't even need to comb. It pretty-much looks the same either way.
