💅 Vertical ridges on fingernails (longitudinal ridges)
Vertical ridges—lines running from the base to the tip of the nail—are very common and usually harmless.
🧠 Most common cause
👴 Aging (normal)
- The most frequent reason
- Nails naturally develop ridges as you get older
- Similar to wrinkles in skin
👉 No treatment needed
🧴 Other possible causes
💧 1. Dehydration of nails
- Dry nails can show ridges more clearly
🍽️ 2. Nutritional deficiencies (less common)
- Low levels of:
- iron
- vitamin B12
- magnesium
👉 Usually comes with other symptoms too
🧼 3. Nail damage or trauma
- Frequent manicures
- Biting or picking nails
🩺 4. Certain conditions (rare)
- Anemia
- Rheumatoid arthritis
- Peripheral vascular disease
👉 Typically accompanied by other noticeable symptoms
⚠️ When to pay attention
See a doctor if you notice:
- sudden appearance of deep ridges
- nail color changes (dark, yellow, white)
- splitting or brittle nails
- horizontal lines (more concerning than vertical)
🧴 How to improve nail appearance
✔️ Simple care tips
- Moisturize nails and cuticles
- Stay hydrated
- Eat a balanced diet
