I've already said my peace, but I just hope no matter what Anya does she can be happy with her hair. I hope she can have it at a length that allows her (and us) to enjoy all it's benefits with minimal problems.
I hope we can all take comfort in the fact that no matter how short she cuts it she's still going to be the same remarkable woman we love and desire.
And as she said, if anything is cut it will be to knee length and nothing less and that's still more than plenty to enjoy.
