Supermodel and “Project Runway” star Heidi Klum is lending her sophisticated good looks to Unilever to help launch its new Clear Scalp & Hair Beauty Therapy, which the multinational calls “a revolutionary line of nourishing shampoos and conditioners that turns the conventional hair care discussion on its head.”  This new approach, according to Unilever, “feeds scalp,” not just the ends, and gives women stronger, more beautiful hair in just seven days, thanks to a “breakthrough technology,” called Nutrium 10. Klum appears in TV, print and digital spots.
