THE LOOK Sleek and straight HOW-TO Beyonce's stylist Kim Kimble got this look by adding a few drops of her Sleek straightening serum to Beyonce's damp locks and then blew her hair out straight using a paddle brush. She finished by smoothing over the hair with a Linea Pro diamond flat iron. INSIDER TRICK Kimble used a thermal ionic paddle brush. "Because of the ionic properties, it helps to straighten the hair and tighten the cuticles, so hair looks smooth and shiny when you blow-dry it," says Kimble.
