💅 Nail Ridges
Nail ridges are lines or raised grooves that appear on fingernails or toenails. They are very common and usually harmless, but sometimes they can signal a health issue depending on their type.
🔍 Types of nail ridges
📏 1. Vertical ridges (most common)
- Run from cuticle to tip of nail
- Become more common with age
- Usually harmless
👉 Often caused by:
- Normal aging
- Mild dehydration
- Minor nutrient imbalance
📐 2. Horizontal ridges (Beau’s lines)
- Run across the nail (side to side)
- More serious than vertical ridges
👉 Can be linked to:
- Severe illness or infection
- High fever or stress
- Injury to nail matrix
- Nutrient deficiency
🧠 Possible causes of nail ridges
- Aging
- Nutrient deficiencies (iron, zinc, B12)
- Dehydration
- Skin conditions (eczema, psoriasis)
- Trauma to nails
- Thyroid issues (in some cases)
🥗 Nutrients that support healthy nails
- 🥚 Protein (eggs, meat, legumes)
- 🥬 Iron (spinach, lentils)
- 🥜 Zinc (nuts, seeds)

⚠️ When to see a doctor

✔️ Bottom line
Most nail ridges—especially vertical ones—are normal and harmless, but sudden or horizontal ridges may indicate stress, illness, or nutrient deficiency.
If you want, I can also show you how to tell if your nail ridges are harmless or nutrient-related based on appearance.
