Tip 7: Get a voluminous straight look For a fuller, more voluminous look -- like the one seen here on Jennifer Aniston, you will want to hold the iron a bit differently. Moticka says to iron from the mid-shaft to ends, still moving the iron straight out to the sides, lifting from the scalp. "As a rule, I do not drag the iron down when working, because it tends to put creases in the [hair] if you are going against the growth pattern," she continues. For added flip, twist your wrist slightly away from your face once you've reached the end of a straightened section for a bit of bounce. Mist with a shine spray or flexible hold hairspray.
