A friend of mine has an odd ritual/habit. He'll grow his hair and beard out really, really long without touching it, until he looks like he escaped from the original Woodstock. Then, suddenly, he'll shave himself bald and clean-pated, and start the process over again. Perhaps you should take up a similar ritual. You may be attached to your hair, and indeed something that long is an achievement, but maybe it's best to face up and start anew.
