That's not the only reason' it's just plain unruly. If it curled attractively instead of sticking out randomly, I might encourage it. The only time it looked all right was when it was long; then the weight made it merely wave and behave itself more (if it looked rather 40s). I recently found a charcoal portrait of me done when I was in Rome, and I didn't recognise it at first. I thought for a moment that I'd done one of Jenna! My face was thinner then, but the artist must still have flattered me. :-)
