I get those also. I'm 2a/2b but since going CG (2 mo) I've started getting them underneath. I love them! I think they're super cute and wish I had more. I have no idea really what I'm doing to get them other than cowashing... I haven't figured out a routine yet in terms of plopping/scrunching etc. or stylers.

Also I think high porosity, normal elasticity, medium density, medium-fine.
