Heidi Klum on the December cover of InStyle magazine

Project Runway’s Heidi Klum is gracing the cover of the new InStyle magazine.

Heidi is wearing a sexy Versace number on the cover along with huge statement cuffs from jeweler Lorraine Schwarz. When asked what kind of shampoo she uses (and the girl does have gorgeous locks), Heidi said she’s a fan of Schwarzkopf Gliss Kur shampoo for blonde hair and the conditioner. She said it works great for color treated hair.
