Shaving and starting over won't necessarily mean your everything will fill in nicely. The only way to know what your situation is is to see a derm who knows a lot about hair loss. Depending on what you may have, the help may be injections in the scalp (alopeocia aerata sp?) which is balding spots, healthy living adjustment to include stress management, rogaine, or maybe nothing. I'm in the nothing category and wish I would have seen a good derm before spending a ton of $ on so much snake oil that is advertised to help or cure.
