How to increase the breadth of my head? my head is narrow laterally kinda compressed... i want to get a better shape of my head?

The bones of your skull determine head shape. The only way to change that is with MAJOR surgery, which would not be done at your age in most cases. Your hair style can be changed to modify the appearance of your head. See a hair stylist or a good barber who can help give you an appearance that is pleasing to you. A shaved head or very short hair would make your head shape more obvious.

Changing the shape of the head is hard, and saved for rare birth defects that can effect brain development or to repair trauma. At 18, the shape is set; however, it can be enhanced with a well selected hair style. If the narrowing is of facial structures, like the cheek bones, temples facial fillers or implants may also be an option.
