I permed after straightening...turned out wonderful. I got so tired of trying to deal with my curls so got this idea to straighten with a box of something I found at walmart. It turned out really nice, but after a few months I started to really miss my curly hair. I spent many hours online trying to find out if the curl would come back or if I would have to cut it off and grow it out again. The general consensus was that it would NOT come back without cutting the straightened part off. I figured that I was going to have to cut it really short anyway so why not see what would happen if I permed. My husband did it for me and I am sooooo happy now. It was kind of frizzy for a few days, but now it looks just as it did before I straightened!
