Love her hair! Take a barrel curling iron or a wand curler and take big sections of your hair, curl and tease for this look. Also, To make it look messy like in this picture, curl towards and away from your face in different sections.
The Braided Knot: Split hair down the middle like you're going to put it in pigtails. Braid each section back, away from your face. With each braided section in each hand, tie hair in a knot, and pin any loose ends into place with bobby pins.
