Beauty salons are another very dangerous area as they sometimes do not properly disinfect tools. This is probably the main reason why women are more prone to having nail fungus than men, another reason is the habit of having long nails so it is easy to break nails.
Toenail fungus, on the other hand, affects both sexes equally. Toenails are most affected by infection because the warmth, darkness and moisture inside the shoes provide a good environment for the fungus to grow. Also, because they are hidden from view, little attention is paid to maintaining proper hygiene and cleanly cut nails. In addition, the feet are also subject to a very high level of stress from daily activities, causing the nails to break frequently.
Nail fungus is one of the biggest health issues affecting the nails and once you are infected it becomes very difficult to get rid of it completely. People will tend to accumulate disease over the years, so the older you are, the more likely you are to have a nail fungus problem.
In short, what causes nail fungus in your body and environment in a situation where it can thrive and be in a place where it already exists.
