Throughout the past month of international fashion shows, too, session stylists have been churning out loose, glossy waves. At Paul Smith, L'Oréal session stylist Peter Gray put all his models beneath inflatable gold hoods. He said: "Unlike a blowdryer, hoods diffuse heat over the whole head to remove moisture and set' the hair. They're fast, inexpensive [less than £10 each] and great for creating waves that last for days."
