This week’s tip comes courtesy of American Idol stylist, Dean Banowetz. This stylist to the stars, who's worked with the likes of Kelly Clarkson and Jennifer Hudson, tells us how to get Kate Hudson’s sexy summer waves with one of the most talked about hot iron tools—the InStyler (the rotating hot iron shown below, $60):

“After shampooing and conditioning your hair, apply a sea salt spray to enhance your hair’s natural texture. Then, take large sections of hair and wrap them around the barrel of the InStyler. Close the tool and allow the barrel to create long lasting waves. Repeat this process until you achieve the desired look. This simple and effortless style is bound to turn heads.”

Many thanks to Dean for telling us how the InStyler gets hair in shape for summer!
