MPB is not reversable by any sane method, or any other one at all. Don't do drugs, plugs or rugs--it's a waste of money and can be dangerous to your health.
I think if you are old enough to shave your face, you can give headshaving a try. If you really do not like it (I think you will), it will grow back to a buzz cut in about a week. As far as being neat and polished, like saint said, the whole package is what will be noticed.Don't be sloppy in dress, have a nice tight buzz if you don't want to shave yet. Come in with confidence, and the rest will fall into place. Good luck.
