hi anton,
have you tried holding a mirror up to your head and looking at it from all the angles?
that's what i did when i was in your position, and to be totally honest, it looked better than i had hoped after i had shaved it.
Also, think about this, with thin hair on your head, people KNOW that you are losing it, whereas with no hair on display, they can only wonder whether you are forced to shave or you do it by choice.
Everyone thinks I choose to shave, for example.
I still have some left on top, but nothing close to a full head.
