Emo hairstyles are usually spiky and shaggy a definition of how you felt at that time. It's an all over the place crazy style so use gel and hair glue to your advantage. Adding hair glue to the bangs in the front to make them straight and stiff is a must when trying to create the emo hairstyle. You can add gel to the back of your hair as well to make it stand straight out if you have the back shorter. If the back is long and shaggy just mix and match gel and hair glue to make it a crazy bold effect. Remember the more unusual and different your hair looks the better off you are.
