There are several reasons why your toenails may be discoloured. Toenail fungus, shoes with poor circulation, feet that sweat profusely and even nail polish can cause your nail colour to look abnormal. Luckily there are a few things that you can do to fix this sometimes embarrassing problem. If the problem persists you may need to seek medical attention by a podiatrist, as the problem may be a little more severe than simple nail discolouration.
Soak a cotton ball in nail polish remover. Remove any nail polish that may be on your toenails. The darker the nail polish, the more easily your toenails can be dyed or discoloured.
Clip and file your toenails so they barely peek over the end of your toe. This will keep your toes neat, preventing the nail from getting caught on threads from your socks or shoes that can be irritating. This will also clip away any fungus that may be on your toes.
Apply a clear, medicated nail polish to your toenails. This polish will help to clear up any fungus and restore your natural nail colour. Reapply the polish as directed on the bottle.
Sprinkle medicated foot powder on the inside of your shoes to help absorb moisture and prevent fungus.
Wear shoes, like flip-flops, that allow air circulation around your feet. Always wear shower shoes when showering in a public shower, gym locker room, or your dorm shower.
