CENTER-PARTED WAVES:  "Wavy hair parted in the middle is ot this season," says stylist Nunzio Saviano of the Oscar Blandi Salon.  "The part keeps hair off the face and waves look sexy as they skim the corners of the eyes."  To get this style, spritz wave spray on hair that's 80 percent dry.  Braid all over, let hair fully air-dry, then undo braids.  Try Oscar Blandi Onde Wave Enhancing Spray.
