On the Grey’s Anatomy episode “Ain’t That a Kick in the Head,” while Meredith (Ellen Pompeo) deals with the aftermath of her conversation with Nathan, Amelia (Caterina Scorsone) prepares for her brain surgery to be performed by her professor, Dr. Tom Koracick (Greg Germann). Preparation involves shaving a patch of her long hair. In the promotional photos (like the one above), the effects of shaving look very real.
In a sneak peek video like the one below, we see Amelia bringing the electric razor to her scalp and then we watch long tresses falling but we don’t actually see her move the razor across her scalp. Based on the photo Scorsone posted of herself days before the episode (below), it doesn’t appear that she really did. Grey’s Anatomy airs Thursdays at 8pm on ABC.
