Messy, textured waves might be having a moment, but a glossy blowout never goes out of style. From royalty like Duchess Kate Middleton to the red carpet like Anna Kendrick at the Los Angeles premiere of Mike and Dave Need Wedding Dates, a polished blowout adds a touch of classic glamour to any look (yes, even your simplest T-shirt and jeans ensemble). In Anna's case, hairstylist Craig Gangi used the staple blowout to counterbalance her modern, structured metallic dress designed by Calvin Klein.

The day of, Gangi helped further condition Anna's hair and add volume by starting on damp hair and applying Leonor Greyl Eclat Naturel ($46; and Leonor Greyl Mousse au Lotus Volumatrice ($46; "Don't use too much product," he cautions. "A lot goes a long way, especially with high-end products like these. Less product means hair is touchable, soft and effortlessly beautiful," Gangi says, sharing the secret for the perfect end result.

With the product distributed through Anna's hair, Gangi used a round boar bristle hairbrush to blow her hair out smooth, pinning two-inch sections up as he dried the hair. "I let the set cool off for five minutes, and when you remove the pin curls it creates volume but not curl," Gangi says. Once the hair was cooled and unpinned, Gangi brushed out each section and sprayed with Leonor Greyl Voluforme ($36; to set the blowout without leaving it weighed down.
