Long nails and a beautiful manicure can enhance your attractiveness by several notches. However, everyone should take proper care of their nails. A split or damaged nail can harm your manicure and be painful. Besides, the nail can get entangled in clothing and snag on your fabrics, damaging them. The vertical split is more challenging than the horizontal cut across the edges. This article discusses what causes vertical splits and how to fix them in various ways.
What Causes Your Nails to Split?
Various factors are responsible for split nails. One reason could be the nature of the work you do. Secondly, there can be accidental splits causing injuries. Other natural or forced causes of split nails are as follows.
Biting your nails: Many people chew their nails because of tension or anxiety. Unfortunately, it becomes a habit, leading to split nails.
Exposure to moisture: Continuous exposure to water can make the nails soft and brittle. For example, washing dishes or clothes for extended periods can make your nails moist and tender. Even applying too much nail polish can make your nails wet. Moistened nails snap easily.
Infections: Bacteria, fungi, or yeast can cause nail infections, making them brittle and prone to damage. Some diseases like kidney or liver problems can also weaken the nails, leading to nail splits.
Injuries: Physical injuries are the most common cause of split nails. Besides being painful, these split nails can tear your clothing and get entangled inside your purses or hair, causing more damage.
We shall look at how to fix a vertically split nail. But before that, let us see how to prevent nail splits.

How to Fix Vertically Split Nails
You can fix your vertically split nails in multiple ways. But, we advise you to fix it as soon as possible because delaying can worsen the situation, leading to more damage.
Use nail glue to repair your nail splits
Nail glue can be handy in repairing vertically split nails. The process is straightforward and does not involve using any ingredient except nail glue.
First, remove your nail polish. Follow the traditional nail polish removal methods to remove existing nail polish. You cannot know the extent of the split when you have nail polish on your nails. Use cotton swabs dipped in acetone to wipe off the nail polish carefully. The cotton fibers can get entangled in the cracks. So, you have to be careful. Please do not rub your nails vigorously because it can widen the split.
Next, wash your nail with soap and water. The primary purpose is to keep your fingernails free from infections. Be careful while cleaning your nails because you might worsen the injury.
Use quality nail glue available on our website. Usually, we recommend using nail glue to fix artificial nails and extensions. But it can also help repair nail splits. So, apply a few drops of nail glue over the split and press your nails gently together.
Allow the glue to get set and harden. Generally, nail glue hardens quickly. Therefore, the best nail glue does not take much time to harden. So, you can avoid keeping your nails pressed for a long time.
Reapply the nail polish after the glue dries off. The bond binds the split and strengthens the nail. Gradually, the split gets repaired naturally.
However, we never recommend this method if the split is deep or there is bleeding on the nail bed.
Use fake nails for nail repair
Usually, nail splits repair themselves over a period. The nail keeps growing; thus, you can cut it and remove the split. However, if the partition is superficial and not deep, you can use fake nails to cover it up. Let us discuss the process.
If the edges have split, you can clip your nails as short as possible to remove the split and reduce the snagging area. However, it is better to be careful because you can injure the nail bed if you file too hard.
Clean your nails thoroughly to remove debris. Otherwise, the fake nails do not fit properly. There could be gaps, leading to water accumulation and infections. Besides, dirt does not allow the artificial nails to stick correctly.
Choose the ideal fake accessory that fits your nail perfectly. For example, depending on your preferences, you can go for acrylic or gel extensions.
Use a drop of nail glue to stick the artificial nail. Otherwise, it can flood the area and spill over to the sides or the cuticles. Removing the glue can become challenging. Instead, stick the fake nail to your damaged fingernail and press it gently.
You can file and shape the nail extension to match your other fingernails. You can decorate your nail with similar nail polish.
The tea bag method is a good alternative
Clean the damaged nail with soap and water to remove all risks of infections.
Cut a tea bag or a silk wrap appropriately. It is better to have a size slightly larger than the damaged nail. Silk wraps are the best because they have an adhesive layer that helps them stick to your nail. Otherwise, tea bags are good alternatives.
Apply some nail glue and stick the tea bag on top of the nail.
You can apply gel polish over the tea bag to strengthen the nail. The nail grows naturally and pushes the split out. You can trim your nails and remove the damaged portion.
Final Thoughts
Split nails can be painful. Besides, they can damage your fabrics and cause unnecessary tears. So, it is better to get rid of them. While cutting the nails can help reduce the damaged area, repairing the split nails is possible. We have discussed three simple methods to repair your damaged vertically split nail. However, we advise users to be careful because damaged nails can be painful and cause other injuries to your skin, like scratches.

Frequently Asked Questions
Why do my nails keep splitting vertically?
Vertical splits usually come from dryness, repeated water exposure, nail biting, injury, or weak nails low on moisture. Frequent splitting is often a sign your nails need strengthening and daily cuticle oil.
Can a split nail heal on its own?
The nail plate itself does not heal, but it grows out — a split grows toward the tip over a few weeks and can then be trimmed off. Repairing it in the meantime stops it from catching and widening.
What is the best product to fix a split nail?
For a shallow fresh split, nail glue plus a silk wrap holds it together. For nails that split repeatedly, a gel strengthener overlay such as A'DOR Gel Strengthener protects the whole nail and prevents new splits.
How long does a split nail take to grow out?
Fingernails grow about 3 mm a month, so a split usually grows out in roughly 1–3 months depending on where it started and how fast your nails grow.
When should I see a doctor about a split nail?
See a doctor if the split is deep, painful, bleeding, reaches the nail bed, or shows signs of infection such as swelling, redness or pus. Do not glue a deep or bleeding split.
