LondonDiva has one. Here is the link http://http://journals.fotki.com/LondonDiva/Self_Relaxing/ I just actually used the tutorial for my self relax about an hour ago and I'm sitting under the dryer right now.
I wanted to send a shout out to LondonDiva bc it was GREAT advice! This is the best self-relax I ever did and I don't want anybody else relaxing my hair anymore
