Split nails, also known as onychoschizia, are a common nail problem that affects people of all ages. Whether you’re someone who works with your hands a lot, has been experimenting with nail extensions, or just noticed your nails becoming brittle and breaking for no clear reason—split nails can be frustrating and even painful.
In this post, we’ll explore everything you need to know about split nails: what causes them, how to treat them, and practical tips and home remedies to help you strengthen and protect your nails.
What Are Split Nails?
Split nails occur when the layers of the nail plate peel away or crack, either horizontally or vertically. This condition can be due to physical trauma, nutritional deficiencies, dehydration, or underlying health issues.
There are generally two kinds of nail splitting:
- Horizontal splitting – where the tip of the nail peels in layers.
- Vertical splitting – where the nail splits from the tip down toward the cuticle, creating a potential pathway for infections.
Split nails are more common than most people think, especially in women. While not usually a serious medical issue, they can be uncomfortable and embarrassing. More importantly, they can point to deeper health or lifestyle issues that need attention.
Causes of Split Nails
Split nails don’t just happen out of nowhere. Here are some of the most common causes:
1. Frequent Wetting and Drying of Hands:
Regularly washing your hands, doing the dishes without gloves, or exposure to chemicals can dry out the nails and cause them to split.
2. Excessive Use of Nail Products:
Using nail polish remover, acrylic nails, or gel manicures too often can damage the natural nail bed, leading to splits and breaks.
3. Nutritional Deficiencies:
A lack of essential nutrients like biotin, iron, and proteins can weaken nails, making them prone to splitting.
4. Dehydration:
When your body lacks adequate water, it shows up in your skin, hair, and nails. Dehydrated nails are dry and brittle.
5. Physical Trauma:
Biting your nails, picking at them, or experiencing repeated trauma (like typing or using your nails as tools) can cause them to split over time.
6. Medical Conditions:
Certain health issues such as hypothyroidism, anemia, or psoriasis can cause chronic nail splitting. If your nails are always splitting and you have other symptoms, it may be time to check with a doctor.
7. Aging:
As we age, our nails naturally become drier and more prone to breakage. This is a common cause of splitting in older adults.
Signs and Symptoms of Split Nails
- Nails breaking or peeling easily
- Thin and fragile nail texture
- Pain or sensitivity in the affected nail
- Discoloration or uneven nail surface
- Difficulty growing nails long
Diagnosing Split Nails
In most cases, you can self-diagnose split nails based on their appearance and the symptoms. However, if the problem persists or is accompanied by other symptoms like skin rash, fatigue, or hair loss, a visit to a healthcare professional is recommended.
Doctors may conduct:
- A physical examination
- Blood tests to check for nutritional deficiencies or thyroid issues
- A biopsy in rare cases to rule out skin conditions
Treatment for Split Nails
1. Trim and File Regularly:
Keeping your nails short helps reduce the risk of further splitting. Use a fine emery board and file gently in one direction.
2. Moisturize the Nails and Cuticles:
Use a rich hand cream or oil (like jojoba or vitamin E oil) daily to lock in moisture and improve nail strength.
3. Avoid Harsh Chemicals:
Wear gloves when cleaning or doing dishes. Avoid acetone-based nail polish removers.
4. Take Nutritional Supplements:
Biotin, zinc, and iron are particularly helpful in strengthening nails. However, consult a doctor before starting any supplements.
5. Limit Nail Polish and Artificial Nails:
Give your nails time to breathe. Go polish-free for a few weeks to let the natural nail recover.
6. Hydration and Healthy Diet:
Drink plenty of water. Include protein, omega-3 fatty acids, leafy greens, nuts, and seeds in your diet.
7. Topical Nail Hardeners:
There are over-the-counter nail strengtheners that contain keratin and other proteins to help reinforce weak nails.
Medical Treatments (When Needed)
If your split nails are due to an underlying medical condition, treating the root cause is crucial. For instance:
- Iron supplements for iron-deficiency anemia
- Thyroid medication for hypothyroidism
- Corticosteroids for nail psoriasis (as prescribed)
In extreme cases, dermatologists may recommend protective coverings or minor surgery to remove severely damaged nails.
