Our nails often reflect more than just how well we groom ourselves—they can be silent messengers of our inner health. One common issue people notice is the development of ridges on their nails. These ridges can be vertical or horizontal, and while some are harmless signs of aging, others may point to underlying health problems that deserve closer attention.
If you’ve looked down at your nails and noticed ridges running along them, you’re not alone. In this detailed guide, we’ll explore what causes nail ridges, the different types, associated symptoms, and what you can do to treat or prevent them.
What Are Nail Ridges?
Nail ridges are raised lines or grooves that can appear on the surface of the fingernails or toenails. They may run in two directions:
- Vertically (from the cuticle to the tip)
- Horizontally (from one side of the nail to the other)
While some ridges are a normal part of aging, others might signal nutritional deficiencies, systemic conditions, or skin disorders.
Types of Nail Ridges
1. Vertical Ridges (Longitudinal Ridging)
These ridges run from the base of the nail (cuticle) to the tip. They’re often more noticeable with age and are typically harmless.
Common Causes:
- Natural aging
- Dehydration of the nail plate
- Minor trauma to the nail matrix
- Nutrient deficiencies
2. Horizontal Ridges (Beau’s Lines)
These run across the nail, from side to side. They are usually deeper and more prominent than vertical ridges.
Common Causes:
- Severe illness or high fever (e.g., from COVID-19, pneumonia)
- Chemotherapy
- Uncontrolled diabetes
- Zinc deficiency
- Physical trauma or injury to the nail
- Major emotional or physical stress
Causes of Ridges on Nails
Understanding the underlying causes can help you determine whether your nail ridges are a simple cosmetic issue or a red flag.
1. Aging
As we age, our body produces less oil and moisture, and this includes the nail matrix. This natural dehydration leads to vertical ridges.
2. Nutrient Deficiencies
Low levels of iron, biotin, magnesium, or zinc can impact nail health and lead to ridging. Deficiencies in Vitamin A and protein can also be culprits.
3. Skin Conditions
Chronic skin conditions such as:
- Eczema
- Psoriasis
- Lichen planus
may affect the nail matrix and cause both vertical and horizontal ridges.
4. Trauma
Repeated trauma or injury to the nail bed or cuticle (such as from manicures or nail biting) can disrupt nail growth and cause ridges.
5. Systemic Illness
Some systemic diseases interrupt nail growth temporarily:
- High fevers
- Thyroid issues
- Uncontrolled diabetes
- Peripheral vascular disease
These conditions often lead to horizontal ridges or changes in nail color and thickness.
6. Medications and Chemotherapy
Certain medications, especially chemotherapy drugs, can affect rapidly growing cells like those in nails, leading to Beau’s lines or discoloration.
7. Fungal Infections
Fungal infections can make nails brittle, discolored, and uneven. Ridges may accompany these changes, particularly if the infection is long-standing.
Symptoms to Watch Alongside Nail Ridges
Sometimes, ridges are accompanied by other signs that indicate a deeper issue. Keep an eye out for:
- Discoloration (yellow, brown, or white nails)
- Splitting or brittleness
- Thickening or thinning of nails
- Pain or swelling around the nail
- Changes in nail shape (spooning, clubbing)
If ridges appear suddenly or are accompanied by any of these symptoms, it’s best to consult a healthcare provider.
How Are Nail Ridges Diagnosed?
A doctor or dermatologist will start with a physical examination of your nails and ask about:
- Recent illnesses
- Diet
- Stress levels
- Medications
- Skin conditions
In some cases, further tests might be needed:
- Blood tests (to check for nutritional deficiencies or systemic diseases)
- Nail clippings or scrapings (to test for fungal infections)
Treatment for Ridges on Nails
1. Address Underlying Health Conditions
If a systemic condition like diabetes, thyroid imbalance, or a nutritional deficiency is causing the ridges, treating the root cause is essential.
2. Improve Your Diet
Make sure you’re getting a balanced intake of:
- Biotin (eggs, almonds, whole grains)
- Iron (spinach, legumes, red meat)
- Zinc (pumpkin seeds, dairy, meat)
- Protein (fish, poultry, lentils)
- Vitamin A (carrots, sweet potatoes)
3. Hydrate and Moisturize
Dehydrated nails are prone to ridging. Use:
- Cuticle oils (jojoba oil, vitamin E oil)
- Hand creams with ingredients like shea butter or ceramides
Apply them especially after washing your hands or using hand sanitizers.
4. Use a Nail Buffer—Cautiously
Gently buffing your nails can smooth out minor vertical ridges. However, avoid over-buffing, as it can thin the nail plate and cause further damage.
5. Consider Supplements
If your diet lacks essential nutrients, supplements like biotin or multivitamins may help improve nail health. Always consult a doctor before starting supplements.
6. Avoid Harsh Chemicals
Nail polish removers with acetone, excessive use of gels/acrylics, and frequent exposure to detergents can weaken nails. Opt for gentle, nourishing nail care products.

Prevention Tips for Healthy Nails
While not all nail ridges are preventable, these tips can help minimize your risk:
- Keep nails and hands moisturized daily
- Wear gloves when using cleaning products or doing dishes
- Avoid biting or picking at your nails or cuticles
- Limit salon treatments, especially if tools aren’t properly sterilized
- Don’t use nails as tools to open lids or scratch surfaces
- Stay hydrated throughout the day
- Trim nails regularly and file gently
- Take breaks from nail polish to let nails breathe
- Use base coats with nail-friendly ingredients if you paint your nails
- See a doctor for sudden changes in nail texture or color
When to See a Doctor
While vertical ridges are often normal, you should seek medical advice if you notice:
- Horizontal ridges (Beau’s lines)
- Changes in color or shape
- Sudden onset of ridges
- Pain, swelling, or bleeding around the nail
- Nail separation from the nail bed
These could indicate underlying conditions that need prompt attention.
Ridges on Toenails: Are They Different?
Ridges can appear on toenails too, and they often share similar causes with fingernail ridges. However, trauma from ill-fitting shoes, fungal infections, or poor circulation (especially in older adults or diabetics) are more common triggers in toenails.
Make sure toenails are trimmed straight across, and wear well-fitting shoes with breathable materials.
Myths About Nail Ridges
Let’s clear up some common myths surrounding ridges on nails:
Myth 1: Nail ridges only happen to old people.
Fact: While aging is a factor, ridges can happen at any age due to illness, trauma, or deficiencies.
Myth 2: You can get rid of ridges completely with buffing.
Fact: Buffing may temporarily reduce their appearance, but it doesn’t solve the root cause.
Myth 3: Nail polish causes ridges.
Fact: Nail polish itself isn’t the problem; it’s the overuse of harsh removers and lack of nail care that can lead to damage.
Myth 4: Supplements work overnight.
Fact: It can take weeks or even months of consistent nutrition and care to see visible improvement.
Final Thoughts
Ridges on your nails might be easy to overlook, but they can carry important clues about your health. Most vertical ridges are harmless, especially as you get older. However, horizontal ridges or sudden changes in your nails should never be ignored.
With the right care, a nutritious diet, and awareness of underlying causes, you can support healthy nail growth and reduce the appearance of ridges over time. Always listen to what your body—and your nails—might be trying to tell you.
