NEED one? Yeah probably. Haven't had a hair cut (other than a little clean-up trim ) in about 2 years. Down past my shoulders now, and makes a respectable pony-tail! MOST of my life, I've worn my hair just long enough to piss-off a First Sgt., high & tight, just a little long on the sides. After I got hurt at work, my wife talked me into letting it grow...Couldn't do it...soon as it touched my ears, I was in for a cut...then I had my knee surgery, and she kept after me to let it grow...now, I'm a fvcking hippy! I grow my beard during the winter, and shave it to a goatee during the summer...It's been fun. Never had long hair before...kind of a PITA to care for however...not sure how long I'll let it go...
