Vertical Nail Ridges: Causes & How to Keep Your Nails Healthy

Have you noticed vertical ridges running from the base to the tip of your nails? While these lines are common and often harmless, they can sometimes signal underlying health issues. Let’s explore what causes them and how you can maintain healthy nails.

1. Natural Aging Process

As we age, our body produces less keratin—the protein that forms nails. This can make vertical ridges more pronounced.

Similar to wrinkles on the skin—it’s a natural part of aging. Nails may also become brittle or dry.

What to Do:

• Hydrate nails with natural oils like coconut or almond oil.
• Eat protein-rich foods to support keratin production.

2. Nutrient Deficiencies

Lack of essential vitamins and minerals can weaken nails and cause ridges. Common deficiencies include:

• Iron: Leads to brittle nails and ridges.
• Biotin (Vitamin B7): Essential for nail strength.
• Zinc and Magnesium: Important for healthy nail growth.

What to Do:

• Eat leafy greens, nuts, eggs, and lean meats.
• Consider biotin supplements if recommended by your doctor.

3. Dehydration & Dryness

Not drinking enough water or frequent hand washing can dry out nails, making ridges more visible.

Nails may become brittle and prone to splitting. Often worsens in colder months or after using harsh chemicals.

What to Do:

• Drink plenty of water.
• Apply moisturizing creams or natural oils daily.

4. Poor Circulation

Vertical ridges combined with pale nails can indicate poor blood circulation from conditions like diabetes, thyroid issues, or cardiovascular problems.

Cold hands and feet may be a sign. Slower nail growth is common.

What to Do:

• Stay active to improve circulation.
• Include omega-3s from fish, nuts, and seeds in your diet.

5. Underlying Health Conditions

In rare cases, vertical ridges may signal autoimmune disorders, digestive issues, or chronic illnesses.

Digestive problems can affect nutrient absorption. Conditions like rheumatoid arthritis or eczema may impact nail health.

What to Do:

• If ridges are accompanied by discoloration, pain, or changes in nail shape, consult a doctor.

Final Thoughts

Vertical ridges on your nails are usually harmless but can reflect your body’s overall health. Prioritize hydration, nutrition, and circulation to keep your nails strong and healthy. If you notice sudden or severe changes, it’s always best to seek medical advice.
