Well, the hairdresser did. It was giving me the irrits, with being dry and tangly. So it had to go.
I had no qualms, and I have no regrets. Cutting off my hair was a symbolic move, as well as a practical one - I am letting go of the things that hold me back (not that my hair did, but it annoyed me, so same diff), and moving on.
4 inches less hair, and I feel so much lighter.
