I've been doing this lately and it really does help with my 3b-c curl formation even just using a regular towel.
Any suggestions where to get a good towel just for this?
Poo: KBB shampoo bar or Shikai moisturizing shampoo
CoWash: VO5 kiwi
Cond: Robert Craig, Tresemme Natural, or Fekkai Shea Butter
Leave in/Styling: Grapeseed oil, KBB milk, KCCC, and Aveda Confixor
