Go ahead and shave it. It's very liberating. Honestly, if you pass less than you would like once it's shaved, put on a hat. I shave mine about once a year and it's awesome for the summer months.

I buzz my head. I go about a 3 or a 4 all over. Never been a problem.

Alright, come to think of it, I've been shaving my head with #1 and #2 for a long time now. Mostly because my hair is very thick and I have dry skin which leads to a ton of itching and medicated shampoos haven't helped me be able to stand having much hair at all. But being that I want to keep incognito here and not show myself for fear of my stalkers finding me (and I do have online stalkers), who here can I trust to privately show a picture to just for the feedback? I'm pretty sure I pass since I have always gotten "sir" 99.9% of the time in my life. I'd just like some honest feedback on the buzz cut thing in my case.
