There are many causes for nail fungus. Dermatophytes is a type of fungus that can grown on the skin, hair, and nails. The most common dermatophyte is athlete’s foot, which infects the toenails. You can get infected by anything you come in contact with that has dermatophytes on them. For example, if you’re going to the nail salon make sure everything is sterilized because if not this can cause nail fungus. Also, the shoes you wear are swimming with fungi. Fungi thrive in warm, dark, moist environments. We need to be aware that nail fungus can spread quickly. Therefore, if untreated, other nails will be infected too. At our office we offer a laser and keryflex treatment which only takes 15 minutes to get a beautiful and healthy nail!
