Avoid trimming your cuticles. Even a minor cut alongside your nail can cause infection.
Do not bite or pick at your nails.
To prevent a fungal nail infection:
Keep your feet clean and dry. Dry feet are less likely to become infected. Apply powder to your feet when needed.
Wear clean, dry socks. Change your socks once a day or more frequently if they become wet.
Wear roomy shoes that allow air to circulate around your feet.
Wear shower sandals or shower shoes when you use public pools, spas, and showers.
To prevent problems with artificial nails:
Test for a reaction to the artificial nail by having just one nail applied. Wait several days to see whether redness, itching, pain, or rash around or under the nail or separation of the nail from the nail bed develops.
Do not apply an artificial nail if the nail or the skin around the nail looks irritated or infected.
If an artificial nail does separate from the nail bed, dip your fingertip into rubbing alcohol for 15 seconds before reattaching the artificial nail. This will clean the space between the nails.
Do not wear artificial nails for longer than 3 months at a time. Give your natural nails a month to rest before reapplying artificial nails.
