Chrissy Teigen is the first one to tell you she loves long extensions, but the Sports Illustrated model proves a long “wob” is sexy, too. “Shorter, tousled layers bring out the sun-kissed dimensions in her hair and complement the effortless, laid-back vibe,” notes Sparks. Want to try it? Loosely wrap 1" sections of hair around the barrel of a 1" curling iron, leaving ends out. Alternate the direction of the twist (one section toward the face, the next away from the face) to keep curls from looking contrived.
