Everyone is always asking us how to use your flat iron to create loose, large waves in their hair. Today, we reveal the secret. As shown here, start to rotate your wrist toward the bottom of the piece of hair you are working on. For a tighter curl, start closer to the scalp. If your hair usually holds a curl, you’re ready to go. If it has the tendency to drop when you leave the house, put a mist of light hairspray before you bounce. No pun intended!
