thanks.GVP hair straightener?
I have used the ONO (One n Only) straightener from Sally's. I had to use the black/blue box (for course, resistant hair) to get perfectly straight hair, but it worked well. It didn't seem to damage my hair much, but I was also careful to apply leave in conditioner immediately after using it, and to ALWAYS keep my hair well moisturized. Hope this helps.
