Red Wolf Inquisitor
I get mine cut fairly short to ~1.5-2.5cm. Then other than an occasional brushing I leave it alone for a few months until it's ~5-6cm. I hate it when it's long because it's bleeping hot where I live. I'd go ahead and just shave it off or get a buzz cut if they didn't make me look even more like a Saturday morning cartoon villain than I already do. Bald scientists with a large mustaches tend to make people nervous.
