Suggestion: Hello, this friend. His head is a little small and his skull is particularly sharp. I want to have a plastic head.

My friend, this situation is that the body given to us by our parents has already taken shape. If it is really rectified, it is not recommended. I suggest you try to find a good barber to design a more suitable hairstyle to make up for it. Don't consider anything else. I wish you the best of health!
