Why Are My Fingernails Not Growing? Causes, Signs, and What You Can Do

Fingernails often go unnoticed—until something seems off. Whether they’ve stopped growing, are growing much more slowly, or seem weak and brittle, changes in your nails can signal much more than a cosmetic concern. Healthy nail growth is typically steady and consistent, so if your fingernails aren’t growing—or have stopped altogether—it’s worth paying attention.

Here’s what you need to know if your fingernails won’t grow, have stopped growing, or are growing improperly.

How Fingernails Normally Grow

Fingernails grow from a part of the skin called the nail matrix, located just beneath the cuticle. As new cells form, older cells are pushed out—this is what creates visible nail growth. On average, fingernails grow about 1/8 inch (3 mm) per month.

However, growth rate can vary due to age, health, nutrition, and even the finger itself—nails on your dominant hand or on longer fingers often grow slightly faster.

Common Reasons Fingernails May Stop Growing or Slow Down

1. Nutritional Deficiencies

Lack of essential nutrients like biotin, iron, zinc, or protein can significantly affect nail growth. Since nails are made of keratin (a protein), poor nutrition can weaken their development.

2. Poor Circulation

Conditions that restrict blood flow, like Raynaud’s disease or diabetes, may reduce the oxygen and nutrients delivered to the nail matrix, slowing or halting growth.

3. Injury or Trauma

Physical trauma—like slamming a finger in a door—can damage the nail matrix, causing one or more nails to stop growing temporarily. In severe cases, a nail may not grow back at all.

4. Aging

Nail growth naturally slows with age. Nails may become thinner, more brittle, and take longer to grow out, especially after the age of 60.

5. Fungal Infections

Chronic fungal infections can thicken or discolor nails, leading to distorted growth. Over time, the nail may appear to stop growing or become detached from the nail bed.

6. Underlying Health Conditions

Thyroid disorders, anemia, kidney disease, and autoimmune conditions like psoriasis or lupus can all impact nail growth. If multiple nails are affected, it may indicate a systemic issue.

7. Medications and Treatments

Chemotherapy, beta-blockers, or long-term antibiotic use can disrupt the growth cycle of nails. In some cases, the nails may stop growing altogether until treatment is complete.

What If Only One Nail Isn’t Growing?

When only one fingernail won’t grow, it’s usually due to local trauma or infection. Repetitive strain (like from typing or nail-biting) may also damage the nail matrix. If your nail has stopped growing for several months with no sign of regrowth, consult a dermatologist.

Can Fingernails Really Stop Growing Permanently?

Yes, in rare cases. If the nail matrix is severely damaged—by injury, surgery, or repeated trauma—it may lead to permanent cessation of growth in that nail. This is less common but can happen.

What Can Affect the Growth of the Nail Plate?

Aside from internal health, external factors like excessive exposure to water, harsh detergents, nail polish remover, or acrylic nails can weaken the nail plate and interfere with normal growth. Protecting your hands and nails can go a long way toward encouraging healthier growth.

Tips to Encourage Nail Growth Naturally

• Eat a balanced diet rich in protein, leafy greens, eggs, nuts, and whole grains.

• Hydrate regularly—dehydration can dry out nails and slow growth.

• Moisturize your hands and nails daily to protect the nail matrix.

• Avoid biting or picking at nails and cuticles.

• Trim regularly to prevent breakage and encourage healthy growth.

• Protect nails from harsh chemicals and prolonged water exposure by using gloves.

• Consider supplements like biotin or collagen, but consult your healthcare provider first.

When to See a Doctor

If your nails have suddenly stopped growing, changed shape, or developed discoloration, or if you experience pain or swelling around the nail, it may be time to see a dermatologist or healthcare provider. Especially if multiple nails are affected or you suspect a health-related cause.

Final Thoughts

While it’s normal for nail growth to fluctuate slightly, a significant or prolonged change—such as your fingernails not growing at all—should not be ignored. Nails can offer insight into your overall health, and paying attention to these subtle signs can help you catch underlying issues early.

With the right care and a little patience, nail growth can often be restored—one fingertip at a time.
