Many women this time of year will ask about white stuff on their nails. Why just women you ask? Because today we’re talking about the protein deposit seen on women’s nails from long term polish use.
Usually seen on the great toe, where polish stays on the longest, white keratin protein deposits often occur under polish that has been left on too long.
How can I know that it is just a protein deposit? If it is a keratin protein deposit, it should buff off easily with a 4 way buffer and stay away. The nail plate should buff out to leave a smooth normal looking nail. Leave your polish off for a few weeks to make sure it does not recur. While polish is off, use a nail conditioner such as Elon to nourish and moisturize the nail plate.
What else could it be? A type of fungus called superficial white oncyhomyosis can look similar. It is more likely to be fungus if it is seen on a male or other non nail polish wearer. Attempts to buff the nail are less likely to be successful if it is fungus. Fungus is also more likely to occur on multiple nails.
What causes superficial white onychomycosis? This type of nail fungus is usually caused by a type of fungus called Trichophyton mentag, but can be caused by other types of fungus and yeast as well. Compared to other types of nail fungus, this type often is more superficial and easier to treat topically. To confirm or rule out fungus a clipping of the nail can be sent to the laboratory.
How can I prevent protein deposits in the future? Give your nails some time to recover between pedicures. Use a nail plate conditioner such as Elon, and avoid the use of straight acetone to remove polish. I, Dr Rosenberger, am terrible at all of these things, so no judgement if you just want to buff it off when you see it instead.
