Heidi Klum has got a voluminous updo which gives her a great look and it can look perfect on unwashed, day-old hair. To get her style first tease the top of the head with a comb to add more volume on the limp strands. Next sweep the entire hair into a high updo and leave room at the top of the head, then secure the bun using elastic. Then spray the hair with lots of strong-hold hairspray and comb the hair to the top. Mist the complete hair until you like it and smooth back the sides of the updo. At last pin the hair back using the bobby pins.
