Try not to cry.
Karen Gillan, former Doctor Who companion and pre-Raphaelite muse, shaved her head to star as Nebula the bald bad-ass in Guardians of the Galaxy. We know this. It was worth it. The movie was great, she is still ginger at heart, and her hair was turned into a wig that isn't in the new Star Wars.
Yet watching those wonderful locks disappear, red like the promise of dawn, is so hard to take. Perhaps that's why she has waited so long to upload this video to her Vimeo account.
Karen takes the process in good spirits. You won't.
