"I especially like structured, architectural updos - and not many people let you do that," the hair wiz Orlando Pita said at the Carolina Herrera show earlier today. Herrera, though, is just the kind of designer who appreciates classic, clean lines, which Pita played up in the sleek, tightly coiled updos seen on her runway. "The shape was inspired by a long seashell with a swirl at the top," he said. To achieve the effect, he brushed strands straight and generously misted on By Byron Spirulina Hair Spray for grip. Hair was then parted off to the side and divided into two sections at the back, each of which was rolled in toward the scalp, leaving a loop at the top, and pinned in place. "I need it tighter here," Pita said, cupping the base of a model's updo and ordering a redo. Fact: even the pros don't nail things on the first attempt. The finished result was entirely right for the Herrera woman. "This isn't a jeans-and-a-jacket kind of look - it's cocktails and an event," Pita noted, as the delicate clouds of hair spray settled around him.
