There is a variety of myths about those small white spots on fingernails that occasionally show up. For example, when you were a young child and noticed spots on your fingernails, your mom may have told you it was from “telling a little white lie” or because “you don’t have enough calcium in your body”. The truth is, white spots on your fingernails are actually caused by reasons other than not drinking your milk.
Many people who wear acrylic nails discover white spots on their fingernails once the nails are removed. White spots may be a sign of trauma to the nail bed while the acrylic nails were being applied. Acrylic nails are also known for causing fungal infections, causing spots on nails.
On occasion, noticing a few white spots on your fingernails may be an indication of an allergic reaction to certain products you used on your nail, such as nail polish, polish remover or nail hardener. This may especially be the case if you notice the white spots a few weeks or a couple of months after you used a new product.
Usually, spots on your fingernails are simply caused by a past injury to the nail base (matrix). White spots don’t immediately show up, it may take a few weeks before you notice the spots. They are typically due to a minor injury, such as hitting your fingernail on the counter-top. By the time the white spots appear you probably forgot about hurting your finger.
A nail injury could have been something as minor as excessive pressure being applied during your last manicure. The injury may not have even been noticed when it occurred, so if the white spots show up a several weeks after a manicure, to remedy this problem, you may want to ask your manicurist to be a little more gentle.
Whatever the cause, white spots on your fingernails are only temporary; they’ll go away as your fingernails grow out. Keep in mind that it may take 8-9 months for your nails to completely grow out and for the spots to go away.
