THESE are amazing. I used them for my engagement photoshoot, and I still had a few curls the next day! They were pretty big (wide) curls, but still very pretty. Curls still fell out a bit, but it was still pretty curly and pretty.
I washed my hair. Blow dried dry, used a TINY bit of Paul Mitchell's The Cream, then I put these rollers in all over and left them in until they had completely cooled. (I've noticed that when using an iron, the hair curls but uncurls as it cools from the weight of itself pulling down.) So I bought this to try, and I don't take the curler out until it's completely cool, and the curls stay in really well. After taking the curlers out, I shook my hair and hair sprayed, and I actually had curls!!
