Sometimes Selena Gomez has it in a pony tail. Selena Gomez normally keeps her fringe in front, and takes a bit from the other side to leave down as well. To do this, get a comb and separate your fringe from the back part of your hair, draw the line with the comb, and make sure it is straight. As you do this, use a hair brush to keep the back part from the front part of your hair.
