I have no forehead and the back of my head is flat. What's the best thing to do to make my head as normal as possible. (photo)

your four head size can be made larger but it would take tissue expansion which is a balloon placed under the forehead skin and slowly increased in size in order to create more bald forehead skin. This is something that we do for reconstruction and is probably something that you would not be interested in but I know of no other way to do this.
