Put 3/4 of your hair in a bun at the top of your head and first spray it with the heat spray from a distance. then take small sections at a time and go over them again until you feel that it is strait. when your done with part, take your hair out of the bun and leave another 1/4 of your hair out. Follow the instructions until your hair is all strait. Have Fun!!
