I have 2b hair that on some days can be a 3a.
It's very fine.

I find a couple of little dabs of Re:coil - about three pea size drops- on my soaking wet hair, after a leave-in, then topped with a light weight gel (I like Aveda flax and aloe) really pumps up my curls. I plop for 10-15 minutes then diffuse.

I either co-wash, use Deva No-poo or Jessicurl HCC to wash.

Don't get discouraged - you will find a routine that works for you.
