I did my first twist out and the results are ok but not great. I twisted them like box braids. I am relaxed and my hair is about an two inches below my shoulder. For those who use this method, how do you keep the twist from untwisting when you are done and move on to the next twist? I put perm rods on the end but they spun around and some of my ends are going every which way. Also, what do you do at night to keep from smashing them when you sleep? thanks.
