One in 10 people have Nail Fungus. Nail fungus loves to grow in dark, moist places, like our shoes for example! Swimmers, Hockey Players, Runners and other athletes are especially susceptible. Anyone can get it, or should I say catch it? It’s alive and it’s contagious. It can easily be spread during the simple process of enjoying a manicure or pedicure, if the previous client was infected. It can also be spread at the pool, the gym or by wearing the shoes of a person who has it.
