I get a hair cut every few years whether I need one or not. Actually, I just whack it off now and then to donate to Locks of Love, an organization that provides wigs to children who have lost theirs to illness.
Before; hair was a bit below waist length
Snip, Snip
After initial cut
and a donation, about 15 -17 inches
Now I have to learn to comb it again, then figure out how to wear it that doesn't require much skill or time.
