Re: head shape
Unfortunately there isn't much that you can do to change the shape of your skull. That was determined by genetics and by birth. And the skull is a solid bone, so there isn't anything to push around.
If you are that upset about it, find a really good stylist that will style your hair to provide you with the best cut for your face and head shape. Grow a beard or mustache if it helps with your face shape. Good luck!
