Did Demi Lovato take a hairstyle cue from Jason Wu's Fall 2012 runway show? Demi accented her hair with a leather-like wrap at the base of the updo and flyaway-free hair. Her simple eyeliner and lip palette allowed her powerful ponytail to take center stage. To achieve the look, make sure to apply gel to your hair while it's still wet. Slick it back into a ponytail and straighten the hair that's loose to keep it streamlined.
