In this tutorial, we learn how to curl your hair with a straightening iron. To begin, straighten your entire head of hair with a thin straightening iron. When you are finished, section your hair off. Now, take a 1" strand of hair and open it up. Wrap the hair around one part of the straightening iron while it's open and pull down when you close the iron down. Do this on your entire head of hair until it's completely curled. If you want a more loose look, run your fingers through your hair. After you are done, apply hair spray to keep your curls lasting all day.
