At the edgy Queen of Swords hair studio in Bushwick, Brooklyn, “Timothée Chalamet hair” is a popular request. Male, female and gender-non-conforming customers clamor for the same fractal mop of unruly curls that starred in “Call Me by Your Name,” “Wonka” and “Dune.” It’s a “laid-back, sexy” way to look like the hands-down most in-demand actor of the moment, said salon owner Elma Siljkovic, and it’s an easy, squirt-in-some-product-and-go cut for people blessed with fine ringlets like Chalamet’s.
