Over the past seven or eight years I have had a tendency to keep my hair quite short -- like, buzzed with a 2 or 3 short (1/4" or 3/8", I think that corresponds to). A couple of months ago I started to get overdue for a new buzz and I just... didn't? So now my hair is kind of in a Beethoven phase. I'm not sure how much longer I'll hold out, but it's nice to know I can still grow a full head of hair.
