Really? The only benefit that I got from wrapping was that it kept my hair straight when I wore straight styles, but I've never heard it benefitting hair growth.
I wear the bun most of the time, so to wrap at night, then comb it down and try to brush it back into a bun in the morning is a little too much for my hair. I'd rather sleep with it pulled back in the same direction that I'm going to style it in the morning.
JaneB, I think you will see your sides improving if you sleep with it pulled back and in a scarf.
