Nearly half of adults notice ridges in their toenails at some point, but many don’t realize what’s causing them or the time to worry. Should you’ve spotted lines or grooves on your nails, they could signal anything from normal aging to concealed health concerns—some harmless, others worth checking out. Comprehending the difference helps you take action, whether it’s tweaking your diet or seeing a doctor. Let’s analyze six key reasons those ridges appear and how to fix them.
Aging and Vertical Ridges in Toenails
As you age, you might notice faint vertical ridges forming on your toenails, like tiny grooves running from the base to the tip. These ridges are often harmless and simply a natural part of aging, as your nails grow slower and cell turnover decreases.
Dry skin or skin conditions like eczema can make them more noticeable, especially as you get older. Sometimes, nutritional deficiencies—like low iron or zinc—play a role in their appearance, so eating a balanced diet helps keep your nails healthy.
While vertical ridges usually don’t need treatment, moisturizing your nails and addressing any fundamental health issues can improve their look. In case they bother you, gently buffing them smooths the surface without damaging the nail.
Just keep in mind—they’re often just a sign of time passing, not a cause for worry.
Horizontal Ridges and Underlying Health Conditions
While vertical ridges in toenails are often just a normal part of aging, horizontal ridges tell a different story.
These deep grooves, called Beau’s lines, signal a temporary interruption in nail growth, often due to fundamental health conditions. Severe illnesses like pneumonia or heart attacks can trigger them, as can viral infections like COVID-19, whenever your body’s under stress.
Chronic issues like diabetes or disease could also cause recurring ridges by disrupting blood flow to your nails. Nutritional deficiencies, especially low zinc, can play a role too.
Should you notice sudden or persistent horizontal ridges, don’t ignore them—consult a healthcare provider to rule out serious conditions. Your nails could be hinting at something deeper.
Nutritional Deficiencies Affecting Nail Health
Your toenails can reveal more than you believe—especially at the time ridges show up due to missing key nutrients. Nutritional deficiencies, like zinc deficiency or iron deficiency, often disrupt nail health, leading to ridges. Zinc shortage can cause Beau’s lines, while low iron can create vertical ridges. A balanced diet packed with vitamins and minerals supports strong nail structure, but sometimes supplementing helps fill the gaps.
| Deficiency | Nail Change | Solution |
|---|---|---|
| Zinc | Beau’s lines | Eat nuts, seeds |
| Iron | Vertical ridges | Add leafy greens |
| Biotin | Weak nails | Try supplements |
| Protein | Thin nails | Include lean meats |
| Vitamin C | Slow growth | Citrus fruits |
Focus on nutrient-rich foods to keep your nails smooth and healthy.
Trauma and Injury as Causes of Toenail Ridges
Should you have ever stubbed your toe or dropped something heavy on your foot, you may notice ridges forming as your toenail grows back.
Repeated pressure from tight shoes or high-impact activities can also damage the nail bed, leading to uneven ridges over time.
Protecting your feet with proper footwear and padding can help prevent these issues.
Nail Impact Damage
Stubbing your toe or dropping something heavy on your foot doesn’t just hurt in the moment—it can leave a lasting mark on your toenails.
Impact damage disrupts nail growth, causing ridges or bruising as the nail recovers. Here’s how trauma affects your toenails:
- Disrupted Growth: A hard hit can temporarily stop nail production, leading to horizontal ridges (Beau’s lines) as the nail regrows.
- Bruising & Discoloration: Severe impacts could cause blood to pool under the nail, altering its color and texture as it heals.
- Uneven Formation: Trauma can distort the nail’s shape, creating ridges or bumps until the damaged section grows out.
Wearing protective footwear and being mindful during activities can help prevent these issues.
Should ridges persist, consult a doctor to rule out fundamental problems.
Repeated Pressure Effects
Several everyday habits—like wearing tight shoes or pounding the pavement during runs—can quietly damage your toenails over time. Repeated pressure or trauma from ill-fitting shoes or injuries disrupts nail growth, leading to ridges like Beau’s lines or brittle nails (onychorrhexis). Even minor bumps add up, leaving dents or splits as your nails grow out.
| Cause | Effect on Toenails |
|---|---|
| Tight shoes | Pressure ridges, Beau’s lines |
| Running/high-impact sports | Horizontal ridges, nail thinning |
| Stubbing toes | Dents, temporary nail deformity |
| Dropping heavy objects | Deep ridges, discoloration |
| Poor nail protection | Onychorrhexis, brittle nails |
To prevent this, wear roomy shoes, cushion toes during workouts, and trim nails straight across. Small changes protect your toenails from long-term damage.
Skin Conditions Leading to Nail Abnormalities
Should you have ridges in your toenails, your skin could be the culprit—conditions like psoriasis can mess with your nail growth, causing deep grooves or pitting.
Eczema, too, often leaves its mark by making the skin around your nails dry and inflamed, which can lead to uneven texture.
These skin issues don’t just affect your skin; they sneak into your nails, changing how they look and feel.
Psoriasis and Nail Ridges
Psoriasis isn’t just a skin issue—it can leave its mark on your toenails too. This autoimmune condition often causes nail abnormalities, including ridges, due to inflammation disrupting the nail matrix.
Should you notice vertical or horizontal lines, it could signal a flare-up affecting nail health.
Here’s what you should know:
- Cause: Psoriasis triggers inflammation in the nail bed, leading to ridges as growth is uneven.
- Signs: Look for pitting, discoloration, or thickening alongside ridges—common in 50% of psoriasis cases.
- Treatment: Dermatological therapies, like topical creams or systemic meds, can improve skin health and reduce nail dystrophy.
Managing psoriasis with your doctor helps protect nail health. Don’t ignore changes—they’re clues to your overall condition.

Eczema’s Impact on Nails
While you might consider eczema only affects your skin, it can also cause noticeable changes in your nails. The inflammation from eczema disrupts nail health, leading to ridges, especially vertical ones, and brittle nails prone to splitting (onychorrhexis).
Flaky, itchy skin around your nails worsens the problem, making them weak and uneven. Your nail growth could slow or develop horizontal ridges should inflammation be severe.
To manage these abnormalities, focus on hydration—moisturizing your nails and cuticles daily helps reduce dryness and inflammation. Use gentle, fragrance-free creams to avoid irritation.
Keep nails short to prevent splits, and wear gloves while handling water or harsh chemicals. Protecting your skin from eczema flare-ups indirectly supports healthier nails, so stick to a consistent skincare routine.
Effective Treatments for Ridges in Toenails
Since ridges in toenails can affect both comfort and appearance, treating them starts with comprehending the cause—like hydration, nutrients, or even how your shoes fit.
Here’s how to tackle them effectively:
- Address Nutritional Deficiencies: Should hormonal imbalances or poor nutrition be to blame, focus on a balanced diet or supplements (like biotin or iron) to strengthen toenails.
- Moisturize and Protect: Dry nails worsen ridges, so apply moisturizing creams with urea or natural oils. Avoid harsh chemicals in polishes or removers.
- Gentle Care: Use a soft buffer to smooth ridges, but don’t overdo it. Wear well-fitting shoes to prevent pressure damage.
For stubborn ridges, consult a healthcare provider for targeted treatments. Small changes can boost overall toenail health!
