Nail lines, such as vertical or horizontal stripes, can sometimes indicate underlying health or nutritional issues.
Vertical lines (also called longitudinal ridges) are usually harmless and often appear with age. However, they may also be linked to dehydration or deficiencies in zinc, vitamin B, or iron. Horizontal lines (like Beau’s lines) can be more concerning and might signal interrupted nail growth due to illness, thyroid disorders, anemia, malnutrition, or severe stress.
To help prevent nail lines:
-
Eat a balanced diet rich in vitamins and minerals
-
Stay hydrated
-
Manage stress levels
-
Avoid harsh chemicals or trauma to the nails
While some nail lines are harmless, others could be a sign of something more serious. If you notice sudden changes, deep ridges, or discoloration, it’s best to consult a healthcare provider or dermatologist for proper evaluation.
