Not a problem for me. I keep mine cut to about an 1/8 inch (about 2mm for the rest of you) Picked up a clipper kit from Wal-mart 3 years ago, and just run it over my head once a week or so. Completely eliminated those pesky collision problems, as well as not having to pay a barber.

Ok, my wife just counted, 8593 strands up there and I've only crashed once (wasn't my fault, it was dark).

Sorry, couldn't help it. Nothing constructive to say so I'll just babble.
