Shaved my head when I was 18, while piss drunk... err.. I had taken some Nyquil and wasn't myself at the time. Anyways, it never really grew fully back. Been receding ever since. Made me mad at first, but I really don't give a flying rat's elbow anymore. Hop out of the shower, run the comb through my hair to straighten it out, and I'm off. Low maintance.
