White Spots on Nails: Harmless or a Sign of Illness? Experts Explain

• White spots on nails, medically termed leukonychia, are usually harmless and often disappear naturally.
• The most common cause is minor nail injury, often unnoticed, rather than a serious deficiency.
• Nutrient deficiencies (zinc, protein, vitamins) or excessive chemical exposure from nail products can also contribute.
• Rarely, allergies or fungal infections may cause spots, especially if accompanied by thickening or discoloration.
• While generally normal, consult a doctor if spots persist or other nail changes occur for professional advice.
