Fungus can enter the nail through a cuticle trimming, through an injury near the nail or even a crack on the surface of the skin near the nail.
Killing the nail fungus does not mean you will not get it again. What you need to do is practice good foot hygiene, which, as simple as it sounds, is really tough for some people.
Avoid moist, wet environments, meaning public showers, pools and locker rooms. You’ve got to be careful when you go to the beach, and even when you go to a friend’s apartment.
Be careful when you go for a manicure or pedicure. The pedicurist should avoid trimming the cuticles too short, which creates more opportunities for fungus to infect the nail.
Pay attention to your own apartment and home. You have to clean out your shower stall and check that bath mat you’ve been stepping on for the past few months — it can be infested with fungus.
And check your shoes. Fungus could be alive and well in those favorite sneakers you’ve been wearing for years.
