When you are choosing hairstyles go for ones that keep the hair away from your face particularly your forehead, so this means no bangs. You want to eliminate the very square look so you do this by creating the illusion of height. Create fullness on the sides of the face by using soft curls or hair volume and style the hair so it comes slightly forward on the jaw line.
You need to avoid the straight cuts or the long straight hairstyles. Stay away from having straight lines to the hair and above all do not have a hairstyle that requires a hair part in the center. Opt for layers and soft waves and although short hairstyles are great don’t go for the super short styles, as it will just defeat your purpose.
