Immediate Care For Split Fingernail Cuts

Fingernails and toenails can be prone to splitting, and this can be caused by a variety of factors, including injuries, harsh chemicals, moisture, skin conditions, and vitamin deficiencies. If you have a split nail, there are several home remedies you can try to repair it, such as using nail glue or clear nail polish to hold the nail together. However, it is important to note that these are only temporary solutions, and if the split is severe or causing constant pain, it is recommended to seek medical attention to address any potential underlying issues.

How to deal with a split fingernail cut

Temporary fixes: nail glue, clear nail polish, or a gel and silk wrap

Temporary fixes for a split fingernail include using nail glue, clear nail polish, or a gel and silk wrap. These methods can help hold the nail together and improve its appearance while you wait for the nail to grow out and the split to disappear.

Nail Glue

If you have nail glue, you can create a longer-term solution by gluing down a small piece of a tea bag or coffee filter over the tear. Apply a thin layer of glue to the broken area, then lay the tea bag flat over the glue using tweezers. Add another layer of glue over the tea bag and let the nail dry. Once dry, buff the nail for a natural finish, then cover with nail polish if desired.

Clear Nail Polish

If your nail is split horizontally at the edge, you can trim or file down the jagged edges and let your nail grow back naturally while using clear nail polish to hold the keratin together.

Gel and Silk Wrap

A gel and silk wrap can be used to hold the nail in place and provide extra protection to keep it from splitting further. This method is similar to the tea bag technique, but instead, you use a nail-sized piece of silk wrap and apply a gel coat. Once set, you can buff the nail and apply polish.

Prevent further damage: trim the nail, cover with a bandage, and keep it clean and dry

If you've split your fingernail, you can take some simple steps to prevent further damage and keep the nail healthy as it grows back. Firstly, it's important to trim the nail. Use nail clippers to cut straight across the nail, then slightly round the tips of the nails for optimum strength. Filing the nail can also help to smooth any rough edges and prevent the nail from catching. If there is a large tear, you may need to trim away the torn part of the nail.

Next, cover the nail with a bandage. You can apply a small amount of petroleum jelly to the nail before placing the bandage on top. This will help to keep the nail clean and protect it as it grows back. It's important to keep the nail clean and dry to prevent infection. Wash your hands regularly and avoid exposing the nail to excess moisture. You should also avoid harsh nail products and chemicals, as these can dehydrate and damage the nail.

If you need to do chores or other activities that involve getting your hands wet, it's a good idea to wear gloves to protect your nails. Keeping your nails well-moisturized can also help to improve their health and prevent splitting. However, avoid over-moisturizing, as this can also weaken the nails and make them more prone to splitting.

Identify the cause: consider lifestyle factors, underlying health conditions, and nutrient deficiencies

Fingernails can reveal a lot about your health and nutrient deficiencies may affect their appearance. Split fingernails can be caused by various underlying health conditions, injuries, or damage to the nail.

Lifestyle factors

Lifestyle factors that can cause nail splitting include:

• Excess moisture: Frequent wetting and drying of the hands can cause nails to become weak and brittle, making them more prone to splitting.
• Nail cosmetics: The use of nail polish, hardeners, and acetone-based removers can dehydrate and weaken nails, making them more susceptible to splitting.
• Occupational exposure to chemicals: Exposure to harsh solvents and chemicals in cleaning supplies can cause nail dehydration and cracking.
• Nail-biting and picking: Nail-biting and picking are often associated with anxiety or stress and can damage the tissues underneath and around the nail, causing pain and bleeding.

Underlying health conditions

Underlying health conditions that can cause nail splitting include:

• Fungal infections: When fungus enters through small nail cracks or the surrounding skin, it can cause a fungal nail infection, leading to fragile, discolored, and misshapen nails.
• Psoriasis: Psoriasis is a skin condition that can cause nail splitting, and it is often associated with nail ridges or peeling.
• Vitamin and mineral deficiencies: Deficiencies in vitamins, minerals, and nutrients can affect nail health. For example, low calcium levels can lead to dry, brittle nails. Vitamin B12 deficiency can affect nail pigmentation, causing bluish or grey-brown discolouration.

Nutrient deficiencies

Nutrient deficiencies that can contribute to nail splitting include:

• Iron deficiency: Iron deficiency can lead to spoon-shaped nails, also known as koilonychia, where nails appear scooped out.
• Selenium deficiency: Prolonged total parenteral nutrition (TPN) can result in selenium deficiency, causing fingernails to turn white.
• Vitamin A and D deficiencies: These deficiencies have been associated with soft nails (hapalonychia) and longitudinal melanonychia of the nail plate.
• Zinc deficiency: Zinc deficiency can manifest as depressions or white lines across the fingernails, known as Muehrcke's lines.

Long-term prevention: wear gloves for chores, avoid harsh nail products, and keep nails moisturised

To prevent nail splits, it is important to protect your nails and hands by wearing gloves when your hands are exposed to water and wet conditions. This is especially important if your job involves frequent hand washing or if you are doing chores or food preparation at home. Cotton-lined rubber gloves are recommended for this purpose.

You should also avoid harsh nail products and chemicals such as nail polish, nail polish remover, and nail hardening products that contain formaldehyde or acetone. These can weaken and dehydrate your nails, making them more prone to splitting. Instead, opt for gentle manicures and use a moisturiser on your nails and cuticles to keep them well-hydrated. Thick moisturisers or petroleum jelly can be particularly effective in improving nail hydration.

Additionally, maintaining a healthy diet rich in vitamins and minerals can contribute to nail health. Nutrients such as vitamins A, B, C, and D, as well as iron, zinc, and calcium, are all important for strong and healthy nails. However, it is always advisable to consult a doctor or medical professional before taking any supplements.

When to see a doctor: if the split is severe, there is a nail infection, or the nail bed is exposed

Fingernails are made of layers of keratin, a type of protein. Healthy nails are smooth, with consistent colouring and no spots or discolouration. They don't have pits or grooves, although they may have vertical ridges.

If you have a split nail, you should see a doctor if the split is severe, there is a nail infection, or the nail bed is exposed. A severe split may require a doctor to remove the nail completely and stitch the nail bed. If possible, doctors can reattach the nail using stitches or glue.

A nail infection may be caused by a fungal, bacterial, or yeast infection in the nail bed, which can change the texture of the nail, making it weaker and more prone to splitting. Yeasts or moulds can enter your nails, making them more likely to crack or break. This is more common in toenails than fingernails. Doctors usually treat fungal infections with prescription antifungal pills. In severe cases, they might need to remove the nail.

The nail bed is the part of the finger that creates the nail. If your nail split extends into your nail bed, you may need to visit a doctor. Your nail may have to be removed, and your nail bed may need stitches.
