Oh dear, poor Sam! And Dean’s a little small to be able to manage a nice style like they’d get at the hairdressers, so Sam’s hair will look a little choppy, and Dean never did manage to get it to spike up in the front.
(Still better than Dean putting Nair in the shampoo)
I think there’s no way Dean would get away with it, once Sam woke up and found out what Dean did, he’d get himself pocketed for the rest of that day.
