White spots on nails, also called leukonychia, are usually harmless and fairly common. Here’s what you need to know:
Common Causes
- Minor Trauma:
- Bumping or hitting your nail can cause tiny white spots as the nail grows out.
- Often unnoticed at the time of injury.
- Nutritional Factors:
- Deficiencies in zinc or calcium are occasionally linked, though rare.
- Allergic Reactions:
- Some nail polishes, hardeners, or products can cause temporary white spots.
- Fungal Infection (less common):
- Usually accompanied by thickening, discoloration, or brittle nails.
- Medical Conditions (rare):
- Certain systemic conditions can show nail changes, but isolated white spots are rarely a sign of serious illness.
What to Do
- Usually nothing: White spots grow out with the nail over a few weeks.
- Protect nails: Avoid trauma, biting, or harsh chemicals.
- Check diet: Ensure a balanced diet with sufficient zinc, calcium, and protein.
- See a doctor: If you notice persistent spots, nail thickening, discoloration, or other symptoms, a dermatologist can check for infections or underlying conditions.
💡 Tip: White spots are not caused by calcium deficiency in most cases, despite the common myth. They’re almost always from minor trauma.
