To fix a split nail at home, patch it with tea bag paper and nail glue in about ten minutes: clean the nail, glue the paper over the split, seal it, let it set, then file and buff smooth. If the split has reached the nail bed, file the nail short instead. Then oil your nails daily, because a dry nail is the one that splits.
- Tea bag paper and nail glue patch most splits and cracks in about ten minutes.
- If the split runs into the nail bed, file the nail short instead of gluing over it.
- A split does not close up by itself. It leaves as the nail grows out, at about 3 mm a month.
- Oil your nails daily, because a dry nail is the one that splits.
Which kind of split do you have?
There are four kinds of split: at the tip, down the side, vertical, and down to the nail bed, and where the split starts and which way it runs decides whether you patch it, file it or protect it.
Grab some good light and have a proper look at yours, because the fix is different for each one. The diagram shows all four, and the table puts what to do first.
| Kind of split | What to do | What you will see |
|---|---|---|
| At the tip | Patch it, or file it smooth if it is small | A small split, or a layer lifting at the free edge |
| Down the side | Patch it, then keep the nail short | A crack running in from the corner or the side edge |
| Vertical | Patch it and keep the nail flexible | A line running from the tip towards the cuticle |
| Down to the nail bed | Do not glue it. File short and protect it | A crack that runs into the pink part and may hurt or bleed |
How do you fix a split nail with a tea bag and glue?
A split nail can be repaired at home in about ten minutes with an unused tea bag, nail glue, small scissors and a fine file.
Yes, a tea bag. It sounds like something from the kitchen drawer, but it works because the paper holds the two sides of the split together while the glue sets around it.
- Clean the nail. Wash and dry your hands, take off any polish, and wipe the nail with a little nail polish remover on a cotton pad. Glue holds best on a nail with no oil on it, so don't skip this one.
- Cut a patch. Empty the tea bag, flatten the paper and cut a piece a little bigger than the split. Any tea bag will do. Save the good tea for drinking.
- Glue the crack. Run a thin layer of nail glue along the split, lay the paper over it and press it flat with a toothpick or an orangewood stick. Keep the glue off your skin, because it sticks skin to nail in seconds and that makes for a long afternoon.
- Seal it. Brush another thin layer of glue over the paper and let it set completely before you touch it. No poking to check.
- File and buff. Smooth the edges with a fine file, then buff gently until the patch sits flush with the nail. Add polish if you like.
The patch isn't forever. It holds the split closed while the nail grows out, so check it every few days, and if an edge lifts, press it down with a little more glue or replace the patch.
When should you file a split nail short instead?
File the nail short when the split runs into the nail bed, because glue over a crack that deep sits on skin that is already sore.
File back past the end of the crack so the edge is smooth, keep the area clean, and cover it with a plaster if it catches on things. Filing short is also the quick answer for a small split right at the tip: one or two passes with a glass file and it's gone before it can spread.
Do
- File the moment a nail catches.
- Patch a split before it spreads.
- Keep a glass file in your bag.
Don't
- Peel or tear the split off.
- Bite or pick at it.
- Leave a lifted patch to catch on everything.
Why do vertical splits keep reopening, and how do you stop them?
Vertical splits keep reopening because every grip, tap and twist flexes the nail, and a split that runs from the tip towards the cuticle pulls open a little more each time.
Patch it as above, but let the paper run a little past the end of the split at both ends, so there's something to hold it together. Keep the nail short while it grows out, because a long nail has more leverage on the split. Then look after the nail itself: a dry nail flexes unevenly and cracks, while a hydrated one bends.

What should you do for a broken nail that hurts or bleeds?
A broken nail that hurts or bleeds needs care first and a repair later.
Rinse it under clean water, press a clean tissue or gauze on it until the bleeding stops, and cover it with a plaster. Don't glue over it. Once it's comfortable, file any sharp edge smooth. I'm a nail technician, not a doctor, so if the bleeding won't stop, the pain is more than a knock would explain, or the nail looks different from usual in other ways, please get it looked at.
If it came on suddenly, hurts, is discoloured, thickened or lifting, see a GP, dermatologist or podiatrist.
Why do nails split in the first place?
Nails usually split because they are dry and have taken too many small knocks.
The usual suspects:
- Water and detergent, which soak the nail and let it dry out again and again.
- Coarse files, and filing nails when they are wet.
- Using nails as tools, to open tins, lift stickers or prise lids.
- Picking or peeling off gel or acrylic, which takes layers of nail with it.
- Cold, dry air and harsh removers.
Lines that run along the nail without splitting it are usually ridges, which are a different thing from a split.
What daily habit stops nails splitting?
Oil your nails every day, because a hydrated nail bends and a dry one splits.
While a nail is recovering from a split, I oil twice a day, morning and night. Applying the oil takes about 20 seconds, so it's not a big ask.
- Click the pen once. Brush the oil along each cuticle and over each nail, then massage it in with your other thumb. One click is usually enough for ten nails.
- Wear gloves for the dishes. Soaking and drying is what takes the flexibility out of a nail, so gloves on.
- File with a glass file. One direction, dry nails, and the moment something catches.
- Keep the nail short while a split grows out. Less length means less leverage.
A split can't knit back together, so it leaves as the nail grows out. At about 3 mm a month, every 3 mm of split is roughly a month of growing out. Most people notice softer cuticles within days and visible growth within one to two weeks, and results vary.

Questions people ask
How do you fix a split nail without glue?
Brush a thin layer of clear base coat over the split, lay a small piece of tea bag paper on top, and seal it with a second coat. Or file the nail back until the split is gone. Either way, keep the nail short, oil it daily and give it time to grow out.
Will a split nail repair itself?
No. The nail plate is already made, so a split does not close up on its own. It stays until the nail grows out past it, at about 3 mm a month. A patch or a shorter nail stops it catching and spreading in the meantime, and daily oil keeps the new nail flexible.
Why do my nails keep splitting?
Usually because they are dry and take a lot of knocks: water and detergent, coarse files, filing wet nails and using nails as tools. Keep the nail flexible with a daily oil, wear gloves for washing up and use a glass file. If they changed suddenly, or you are worried, ask your GP.
