Hi Doctor,
I got an appointment with a podiatrist and asked him his opinion on nail polish. He said that the reason why nail polish is a 'no-no' is that it traps moisture under the nail and can cause fungus!!!
Yuck~!
fungus lives naturally all over our body and thrives in moist, warm, and dark envrionments. once you colonize enough fungus, you end up with a fungal infection.
if you wear artificial nails (whether drug store or acrylic), you create a condition that would allow fungus to populate and thrive.
wearing nail polish prevents you from seeing the nail. if you get an infection, you may not know about it until weeks later...preventing you from cleaning and brushing the nail.
nail polish alone does not cause fungus infections
