Brazilian bombshell Gisele Bundchen has Hollywood's best hair, according to America's top salons. Elle magazine bosses surveyed the nation's leading stylists and asked them to name the star whose hair is a favourite for their clients. More than 50 per cent gave sexy Giselle the nod, while Sienna Miller came in at number two and Nicole Richie's short bob was voted number three. Natalie Portman's pixie cut came in fourth.
