I agree with happydud-- it /really/ isn't that hard. Though usually when I shower, I wind up sticking any stray shower hairs onto the tile walls and finding the patterns/pictures in them [like clouds and tortillas]. I also usually brush my shampoo/conditioner out of my hair, that way a lot of the stray hairs go onto the brush instead of onto the floor.
FWIW, I also shave my chest and trim my toenails [ick for not..] and sit down to pee [except in public restrooms] and I'm not half-gay.
Incidentally, my hair used to be to my waist, I trimmed it to my shoulder-blades a couple years ago, and last month I chopped my braid off Viking style and it's just barely long enough to pull back into a troll-knot now. Moral: I have a lot of experience with shower hair.

Also, I can kill you with my brain.
