Harry Josh is the one of the hottest celebrity hairstylists in the beauty biz (browse celeb hairstyles that'll look great on your face shape). Seriously, he pretty much has his hands in the hair of this summer's biggest box office bombshells: Gwyneth Paltrow ("Iron Man 2"), chick flick queen Amanda Seyfried ("Letters to Juliet"), and probably every girl's wannabe avatar, Sarah Jessica Parker, who is bringing Carrie and her fabulous curls back in "Sex and the City 2" (see photos of "the girls" then and now here). Oh and by the way, those are just a few of his celeb clients.
