If you shave it, it will grow back.
But I'm with you LittleItaly- if I had hair, I would be a sportin' it. Last time I was able to keep hair in my head, I was 15. All downhill after that.
And as far as getting you dome burnt... well, I have freckles on my bald spot! If I am out in the sun, the dome gets the lotion first!
