shave your head once. You might like it. If you're anything under 15% body fat, it'll look good compared to most people.
Then let it grow back, keep it short, style intelligently, and use that gel stuff that make it look 10x fuller.
Don't be the guy with the birds nest, nor the 5-head. I shaved mine and it looked cool. Grew it back and am enjoying it for another 2-3 years until I have to go shaved forever.
