White lines or spots on the nails, medically called leukonychia, are quite popular. While most cases are harmless and linked to minor injuries or nutritional deficiencies, sometimes these white marks can indicate an underlying health issue. Knowing when to pay attention is essential for your overall well-being.
1. Common Causes of White Lines
- Minor trauma: Hi:tting or pressing the nail can leave temporary white marks.
- Nutritional deficiencies: Lack of zinc, calcium, or protein may cause white lines.
- Harsh chemicals: Nail polish, detergents, or cleaning agents can lessen nails.
- Most of these causes are harmless, and the lines grow out naturally as the nail grows.
