Fingernails can be prone to splitting, and this can happen for a variety of reasons. Nails can split vertically or horizontally, and there are many causes, including aging, injury, exposure to water, harsh chemicals, certain illnesses, and even skin conditions like psoriasis. While there are temporary fixes for a split nail, such as using nail glue or clear nail polish, it's important to address the underlying cause to prevent further splitting. This may involve making lifestyle changes, such as wearing gloves when doing chores, maintaining a healthy diet, or taking supplements with a doctor's advice.

What You'll Learn

Reduce exposure to moisture
Reducing exposure to moisture is key to preventing fingernail splitting. Nails are made of layers of keratin, and in between these layers are small spaces. When nails are exposed to air and water, the spaces between the layers of keratin can swell, making the layers easier to separate, which results in increased breakage.
To reduce exposure to moisture, it is recommended to wear gloves while doing chores, especially those that involve water, such as washing dishes. This will keep your hands dry and protect your nails from harsh chemicals found in detergents and cleaning fluids.
You should also avoid keeping your hands in water for long periods. When you do wash your hands, use a moisturising hand lotion or cream afterwards to lock in moisture. Look for products that contain lanolin or alpha-hydroxy acids, which can help to soothe your nail area and keep your nails strong.
Additionally, you can apply a thick layer of ointment, such as Vaseline, on top of your moisturised nails to seal in moisture and further protect them from water exposure.

Avoid harsh chemicals
Avoiding harsh chemicals is key to preventing nail splitting. Nails are made of layers of keratin, a type of protein, and can be damaged by harsh chemicals found in cleaning supplies and nail polish. These chemicals can dehydrate your nails, causing them to separate and crack.
People who regularly use nail polish and nail polish remover are more prone to dry nails and cracks. The solvents and chemicals in nail polish and nail polish removers can be particularly damaging. It is best to avoid acetone-based nail polish removers.
Occupations that require frequent hand washing or exposure to chemicals can also increase the risk of nail splitting. This includes jobs that involve regular exposure to alkalis, acids, cement, solvents, and thioglycolates. If your job involves regular exposure to these substances, it is a good idea to protect your nails by wearing gloves.
Additionally, it is important to be mindful of the products you use on your nails. Some nail-hardening agents, for example, contain formaldehyde, which can increase nail strength but can also cause brittleness and other nail problems. These products should be used cautiously and only applied to the free edge or growing end of the nail. Acrylate-containing hardeners are also effective, but they may cause an allergic reaction in the skin.

Manage anxiety
Split nails can be caused by a variety of factors, including physical trauma, infection, or underlying conditions such as psoriasis. While nail splitting can occur due to external factors, it can also be a sign of anxiety and stress.
Anxiety and stress can lead to nail-biting, picking, or other nervous habits that weaken nails and make them prone to splitting. Managing anxiety can help reduce these habits and improve nail health. Here are some strategies to manage anxiety:
- Practice self-care: Self-care activities such as regular exercise, getting enough sleep, and maintaining a healthy diet are essential for managing anxiety. These activities can help reduce stress levels and promote overall well-being.
- Explore medication: If needed, consult a doctor or mental health professional. They may prescribe medication to help manage anxiety symptoms. Medication should always be taken under professional supervision.
- Address underlying causes: Identify and address the underlying causes of anxiety. This may include seeking therapy or counseling to cope with traumatic events, chronic stress, or other triggers. Managing anxiety at its source can help reduce associated habits like nail-biting.
- Reduce physical tension: Anxiety can lead to physical tension, which may contribute to improper nail usage and increase the risk of nail splitting. Practicing relaxation techniques, such as deep breathing, progressive muscle relaxation, or yoga, can help reduce physical tension and anxiety levels.
- Improve nail care: Take extra care of your nails to prevent splitting. Keep your nails clean, moisturized, and trimmed. Avoid harsh nail products and frequent nail polish use, as these can weaken nails. Consider using nail hardening products and wearing gloves during household chores to protect your nails from excess moisture and chemicals.
- Address nutrient deficiencies: Stress and anxiety can interfere with nutrient absorption, leading to weak and brittle nails. Ensure you are getting adequate vitamins and minerals, such as vitamins A, B, C, and D, as well as iron, zinc, and calcium. Include a variety of nutrient-rich foods in your diet, such as meat, eggs, fish, seeds, nuts, and vegetables.
- Monitor nail health: Pay attention to any changes in your nail health, such as discoloration, pits, grooves, or ridges. These changes could indicate underlying health issues or the impact of anxiety on your nail health. If you are concerned, reach out to a doctor or dermatologist for advice.

Treat underlying conditions
If you are experiencing frequent nail splitting, it is important to address any underlying conditions or health problems that may be causing this issue. While nail splitting can be caused by physical trauma or injury, it can also be a symptom of an underlying health condition.
One such condition is psoriasis, which affects the skin and nails. Psoriasis causes outbreaks of red, scaly areas on the skin and can weaken nails, making them more prone to splitting. If you suspect you have psoriasis, you should see a dermatologist, who can suggest appropriate medication.
Another potential underlying condition that can cause nail splitting is a fungal, bacterial, or yeast infection in the nail bed. These infections can change the texture of the nails, making them weakened and more susceptible to splitting. If you suspect you have a nail infection, it is important to seek medical attention and receive the appropriate antifungal or antibiotic treatment to prevent further damage to your nails.
Additionally, certain vitamin and mineral deficiencies can contribute to nail splitting. Vitamins A, B, C, and D, as well as iron, zinc, and calcium, are all important for nail health. If you suspect that your diet may be lacking in these essential nutrients, consider consulting a healthcare professional for advice on how to improve your diet or whether supplements may be beneficial.
In some cases, nail splitting may be a result of underlying medical problems such as gland (endocrine system) diseases, tuberculosis, Sjögren syndrome, or malnutrition. If you have any concerns about your nail health or suspect that an underlying condition may be causing your nails to split, it is always best to consult a healthcare professional for proper diagnosis and treatment.

Maintain a healthy diet
Maintaining a healthy diet can help prevent nail splitting. While it is rare, cracked nails can be caused by a lack of biotin in your diet. Biotin, a B vitamin supplement, can help heal your nails. However, it is important to note that you should not take it if you are pregnant. If your nails are still cracking after six months of taking biotin, consult your doctor.
To get more biotin in your diet, eat more meat, eggs, fish, seeds, nuts, and vegetables like sweet potatoes. In addition to biotin, vitamins A, B, C, and D are also important for nail health. Deficiencies in these vitamins can cause problems with nail health. Similarly, not getting enough iron, zinc, or calcium can lead to issues with your nails.
In addition to maintaining a healthy diet, there are other lifestyle changes you can make to prevent nail splitting. This includes wearing gloves while doing chores to protect your nails from harsh chemicals and excessive moisture. Keeping your nails trimmed, washing and moisturizing your hands regularly, and avoiding harsh nail products can also help strengthen your nails.
