Modern Trailering shows how to curl your hair with a curling iron. First turn on the curling iron to a medium or medium-high heat. The video example suggested twenty-five to thirty. Once it is adequately heated, clamp the rods around a small piece of hair close to the base of the head. Using your wrist, turn the iron so that it is coming towards you and begin to pull the curling iron down slowly. It is important not to pull down too slowly or you might burn your hair. Next step is to enjoy your wavy hair!
