At the London premiere of Urchin on Tuesday, Harris Dickinson’s haircut had Kafka energy. Also, Prada’s “depression hair” from last spring, and Billy Elliot from Billy Elliot—the musical about an impoverished coal miner’s son who just wanted to be a ballet dancer. Though Billy Elliot’s hairstyle had more lift than Dickinson’s, they share a jagged, civilian-boy quality like maybe your mom cut your hair at the kitchen table while you were trying to plié. This likely works best if your hair is straight to slightly wavy and medium density. Too fine and it won’t separate, too curly and it won’t lie smooth.
