Hairspray,

I get your trepidation, but action is the most important thing, not words. We can hang around this forum all day being "nice" and speculating that no one will notice, but none of us can ever be 100% certain on that assumption. If things don't work out, shave that shit and call it a day. No one is gonna give you a hard time. Then let it grow back. At least you tried at that point.
