“I use dry shampoo to create more volume and texture, but also to make hair look less ‘done,’” says hairstylist Peter Butler of the magic effects of dry shampoo. “Your style is still there, but it’s softer.” It’s this ability to craft full, lightly textured, universally sexy hair that has put Butler’s work on magazine covers ranging from Vogue to Rolling Stone to Sports Illustrated (he’s done 11 S.I. covers, to be exact) and garnered clients like Claire Danes, Natalie Portman, Kate Upton and Heidi Klum. His expert strategy (outlined below) includes massaging his favorite non-aerosol formula (he prefers powder over spray) into roots, blow-drying away excess (especially helpful for brunettes), then adding luster back into hair with his go-to serum.
