Season 3 Kirk?
Seriously though, I have no idea about how it went down, but do you really think that Avery walked up to Berman (Not Berman. Moore?) one day with hat in hand and said "Please sah, Pleaee Mistah Moore, would it be all right if you let me shave my head?"
The girls on Charmed used drive the make up department insane because they kept showing up every other week with new Tattoos that their Characters did not have, should not have and would not have.
It was arduous.
And those were the ones that behaved themselves.
