FACIAL TYPES AND HAIRDRESSING
If you have a square face you want to elongate your face. You want to make your face appear longer, the same way as a round face;
Keep the sides shorter, while leaving the hair longer on top.
Avoid square cuts as they will make the face appear more square, eg; blunt cuts to the jaw.
Have wispy layers in the front.
A wavy hairstyle covers the squareness of the face.
Avoid super short layers all over (like V1L5, just shorter) because your square face will appear more square.
