What they look like: Nails curve upward like a spoon.
Common causes:
Iron-deficiency anemia.
Hereditary or frequent chemical exposure (e.g., hair dyes).
When to worry: Get a blood test for iron levels.
4. Pitting (Tiny Dents)
What they look like: Small holes or dents.
Common causes:
Psoriasis (30% of patients have nail pitting).
Alopecia areata (autoimmune hair loss).
When to worry: If accompanied by scaly skin or hair loss, see a dermatologist.
When to See a Doctor
🚨 Seek medical advice if you notice:
Dark streaks (could indicate melanoma).
Yellow, thickened nails (fungal infection).
Sudden ridges + fatigue (nutrient deficiency).
Clubbing (nails curving around fingertips—linked to lung/heart issues).
How to Improve Nail Health
✔ Stay hydrated – Dryness worsens ridges.
✔ Eat a balanced diet – Focus on biotin (eggs, nuts), iron (spinach, red meat), and zinc (seeds, shellfish).
✔ Moisturize – Rub cuticle oil or coconut oil into nails.
✔ Protect hands – Wear gloves when cleaning or gardening.
Final Thought
Most ridges are harmless and genetic, but sudden changes can be a silent signal from your body. When in doubt, snap a photo and ask your doctor—especially if paired with other symptoms.
