The polish exchange at Hey, Nice Nails! in Long Beach, Calif., is just what is sounds like — clients are free to drop off a polish they no longer care for and pick up one that sparks their fancy. “We know that a lot of our clients like to impulsively buy polishes, or their friends do, or their daughters do — everyone does nowadays,” says Ginny Geer, who co-owns Hey, Nice Nails! with her sister Donne. “This is a way for ladies to take the polishes they are over and swap them out for some that they like better.”
