Symmetrical features, nice beard, broad shoulders... You'll look good bald! Give it a go! N wear a hat to uni if you really hate it!
I certainly do think you should shave your head however leave the beard alone. You are a handsome young man and any handsome young man would look good completely shaved bald. Go for it. Let us see a pic.
I started thinning at 15, but did not have a bald spot until my mid 30s.
Shave it, don't shave it... attractiveness comes from within, first. Be confident in whatever you do.
