I think I'm finally going to try rollersetting my natural hair. I've read many posts about rollersetting and have looked at pictures of rollersetting. Now, what do I need to know about rollersetting "natural" hair. What's the best way to get my roots as straight as possible? What's the best way to get it as smooth as possible? What's the best way to keep my ends straight? How do I roll it keeping it straight enough so it dries straight enough? Any tips would be greatly appreciated.
