I don't "press" anymore, I just use my flat iron. I'm not sure if you just wanted hot comb info...
I cowash/detangle, use Aphogee 2min Keratin, DC for 45 minutes under heat, cold water/ACV rinse, moisturize/seal (with a VERY TINY bit of EVCO so nothing burns), add heat protectant, braid (to air dry). Then flat iron very small sections on 330 degrees or so, only passing each section twice. Voila!
