Katy Perry is a trendsetter who loves to try out different haircuts and bold hair colors. She looks fantastic with this electric blue, angular bob. This hairstyle works particularly well for a round face, as it creates the illusion of a longer, more oval-shaped face. The neon color adds excitement for any hairstyle or face shape. If you want this look and have the confidence to pull it off, seek out a professional hair stylist to really make your color pop!
