Since you're looking for a simple method with product recs, here's the one that works best for me but mind you the product I use (i only use this once in a while) is not CG; I think there is a cone in there.

Shampoo - CHS treatment shampoo - my absolute favorite; makes my hair unbelievably soft!
Conditioner - GVP Conditioning balm
Leave in - CJ Beauticurls leave in
Product - AB beach bomb

I have 3a curls but get really pretty waves with this method. Just rake the product in and slightly scrunch. I let my hair air dry. Good luck!
