Leave it to Sassoon Salon (formerly known as Vidal Sassoon Salon) to come up with a way to add a modern edge to its impressive lineup of classically chic hairstyles. For its 2011 Autumn/Winter collection, stylists were influenced by Stella McCartney's clothing line and art by Dan Flavin. Think: sharp, well-defined edges and bursts bold color. Blue isn't just plain old blue; it's rich, vibrant royal blue. And green becomes the richest emerald tone you can imagine. Be sure to check out the geometric, colorful styles now.
