Not all haircuts look good in all the boys! Learn what is best according to your type of face.
For a diamond-shaped face, where the cheeks are the widest part of the face, a style layered half-length hair to one side is recommended.
If your jaw is the same width as your cheekbones and your face is long, try to traditional cuts, a little longer on the sides. (Jason Momoa is a good example of this face, but I hope henever cut his hair!)
If your forehead and cheekbones are wide, but your chin is pointed, add volume to the top will lengthen your face and give you balance. If you like beards, growing some on the sides also helps.
