On the Grow and Keeping it Simple
Once a week, if it is only the newgrowth "area' and not the entire length!
This is what I'm doing now. Rollersetting weekly and doing one pass (@ 315degrees) on my newgrowth only. No flat iron touch ups during the week, no blowdryers or curling irons, and I never flat iron my length or ends.
