White spots are also known as leukonychia, which refers to nail’s white discoloration. Usually, white spots are harmless, but in some cases, they might be symptomatic of underlying health conditions.

White spots on nails are common. Some health issues may cause them. The possible causes are mineral deficiency, nail injury, fungal infection, and allergic reaction.

Allergic Reaction

It’s an allergy to nail hardener, gloss, polish or polish removers. It causes white spots on fingernails. The use of gel or acrylic nails may also damage your nails and can cause such white spots.

Injury to Fingernails

While there is no quick fix for the white spots on fingernails, protecting fingernails from the injuries or being mindful of the health may reduce such spots from building up.
