A style that is slightly longer than the chin, shaped and softened around the edges, flatters a square face. This gives the illusion of length to your face. Hair should not be cut shorter than, or in line with the chin, as this would make the face appear squarer. Avoid center partings and straight bangs. For someone with a heart shaped face balance between the forehead and chin is very important. Layered hair shaped along the face near the chin, thick at the bottom and with layered bangs will provide fullness where needed. Straight styles, which cling to the face, would accentuate the narrow jaw line and is not recommended.
For punk short hairstyles you need to incorporate an unusual hair color such as fluorescent pink, green or blue. You can also only color sections of your hair or your whole head. It is possible to do color stripes, color the tips of your hair or just the bangs. The color needs to stand out so if you have very dark hair then platinum blond tips are a good choice. The main factor when getting a punk cut is that it should not be any cut that is considered mainstream. This can usually be overcome by having unusual configurations such as long shaggy hair on top and a short buzz cut on the bottom. Asymmetrical cuts also work. It is also very typical to have words shaved into your head.
