I don't know if this is the *best* but one I was just thinking about this morning - staying away from brushes! I can't believe how they pull my wave out. I don't even use a comb very much anymore except every few washes, otherwise I finger-comb when I have conditioner in and that's it. Before I would have thought not brushing my hair every day was nasty, but it actually is a huge help.
2b (with some straight under-layer, grrrrr)
Normal porosity, low elasticity, medium texture

(according to CurlGenie - HUGE surprise, I always thought I had fine hair and my stylists always agreed)

Tried CG for a summer, but it wasn't for me. I don't load up on sulfates and silicones, but I have no shame in using them when I want/need to! Currently loving LOOB.
