💅 Vertical nail ridges
Vertical nail ridges (also called longitudinal ridges or onychorrhexis) are lines that run from the base of the nail to the tip.
🧠 Are they normal?
Yes—in most cases they are harmless, especially in adults and older people.
Doctors note that:
- Mild vertical ridges are very common with aging
- Often not a sign of serious disease (Mayo Clinic)
🔍 Common causes
🧓 1. Aging (most common)
- Nails grow more slowly with age
- Slight ridge formation is normal wear-and-tear
(Cleveland Clinic)
💧 2. Dry nails / dehydration
- Nails lose moisture
- Can look rough or lined
🧴 3. Nutrient deficiencies (sometimes)
- Iron deficiency
- Zinc deficiency
- Vitamin B12 issues (less common)
(Healthline)
🧴 4. Skin conditions
- Eczema
- Psoriasis
- Dry skin disorders
🦋 5. Medical conditions (less common)
- Thyroid disorders
- Chronic illness or circulation issues
⚠️ When to worry
See a doctor if ridges come with:
- Nail color changes (yellow, dark, white patches)
- Pain or swelling
- Sudden worsening in many nails
- Nail splitting or deformity
🧴 Simple care tips
- Moisturize nails and cuticles regularly
- Eat protein + iron-rich foods
