Hair Today. Gone Tomorrow?

I just confirmed my Thursday hair cut appointment.  It’s been seven weeks since my hair has been trimmed!  I usually get it trimmed every three weeks.  Yesterday and today I can say; “I don’t need a hair cut” with confidence.  Sure as I cancel that appointment I’ll wake up with bed head that will embarrass me at the gym.  And then again, perhaps not.  What’s a girl to do?
