I also have a very high forehead, at least I did. When you have a close buzz or shave your forehead kind of blends in with the rest. If you look at my profile picture you'll see what I mean. When you have hair the size of the forehead is, IMHO, more noticeable. If you want to try it go ahead. Once you get used to the buzz you might want to try going even shorter, and, eventually maybe even try a nice smooth shaved look. I think it would look good on you.
