Kate Bosworth is always impeccably dressed and flawlessly complected, but it was her soft, slightly waved hairstyle, which she wore at a recent event feting Charlie Chaplin, that stood out most. This lightly textured coiffure is surprisingly easy to do at home; as it turns out, it's all in the sectioning.

  • The prep: Kate's go-to stylist, Luke Chamberlain, started by applying Leonor Greyl Volumatrice Mousse on four preparted portions of hair. He then blow-dried her strands section by section, using a medium-barreled, boar-bristle round brush for volume.
  • The finish: "After the blowout, I took large vertical sections and only curled the ends, allowing them to cool in one-inch Velcro rollers," Chamberlain explained. Once set, he removed the rollers, brushed out Kate's hair, and added some Oribe Dry Texturizing Spray for a slightly undone feeling. And that's how you, too, can make waves.
