The hair at Givenchy's Paris fashion week show took hours to complete. Hairstylist Luigi Murenu created a head full of flat, pinned curls on the models, all doused in colours including peach, blue and purple. We can only liken it to a '50s style swimming cap. A little bit of trivia for you, lead model Natalia Vodianova (above) ran the Paris Marathon before walking in the show. They don't call 'em supermodels for nothing!
