Toenail care at home: trimming, filing and prevention

Toenails need less attention than fingernails, but the attention they do need matters. A few minutes every couple of weeks, done the right way, keeps nails comfortable in shoes and makes each pedicure simpler. Done the wrong way, trimming is one of the most common causes of ingrown toenails.

This guide covers the tools worth having, how to trim and file step by step, how to look after the skin around the nail, and the situations where home care should stop and a podiatrist should take over.

The right tools

• Straight-edged toenail clippers. Larger and sturdier than fingernail clippers, with a straight rather than curved blade.
• A fine nail file. A gentle grit is kinder to the nail than a coarse one.
• A soft nail brush. For lifting debris from under the free edge without poking at it.
• Cuticle oil or a rich cream. For the skin around the nail.

Keep your tools clean and dry, wash them after each use, and do not share them. Replace files when they wear smooth. Leave out anything sharp and pointed for digging under the nail or into the corners: it is the quickest way to break the skin at the side of the nail.

Before you start

Trim after a bath or shower, when nails are softer and less likely to split. Pat your feet dry first, so the clippers do not slip, and sit somewhere with good light where you can bring your foot comfortably close without straining.

Take a moment to look at each nail before you cut. Note the natural line of the toe, where each corner sits, and whether any area looks red, sore or different from usual. If something does, leave that nail alone for now; the section on seeing a podiatrist below explains why.

How to trim

1. Cut straight across. Follow the line of the toe rather than curving into the corners. A straight edge keeps the corners sitting on top of the skin, where they belong.
2. Leave a little length. The nail should be roughly level with the tip of the toe. Cutting too short leaves the corners free to grow into the skin.
3. Work in small cuts. Several small snips are gentler than one large one, which can crack a thick nail. Start at one side, move across, and finish at the other.
4. Do not dig into the corners. If a corner feels sharp, smooth it with the file instead.
5. Check the edge. Run a fingertip along it. Anything that catches is a job for the file, not another cut.

The big toe takes most of the pressure from shoes, so it deserves the most care. Smaller toes often need only a light trim, and some barely need cutting at all between pedicures.

If a nail tears or splits, trim just past the damaged part with a straight cut and smooth the edge with the file. Avoid cutting further back to make it match the others; a slightly shorter nail simply grows back, whereas a nail cut too far down at the corners can start to press into the skin.

How to file

File in one direction, from the side towards the centre, rather than sawing back and forth, which can fray the edge. Keep the shape square with just the sharpest points softened. Avoid filing the surface of the nail: thinning it makes it weaker and more prone to splitting.

File with the nail dry rather than straight out of the bath, since a softened edge tends to tear under the file. Hold the file level with the end of the nail, not angled underneath it, and use light strokes. If you find yourself pressing hard, the file is probably worn or too coarse.

The skin around the nail

The cuticle at the base of the nail is a seal that helps keep infection out, and there is no need to cut it. After a shower, push it back gently with a soft towel, then massage in a little oil. Do the same along the sides of the nail, where skin can dry and harden against the edge.

If a small flap of loose skin catches, trim only that loose piece with clean scissors, close to the base and without pulling. Never tear it, and never cut living skin.

Sturdy or hard-to-cut nails

Some toenails, particularly the big toes, are naturally thick and firm. Trimming after a bath, taking smaller cuts and keeping your clippers sharp makes them easier to manage.

A nail that has become noticeably thicker than it used to be is a different matter, as is one that has yellowed, darkened or started to crumble. These changes are worth having looked at by a podiatrist or doctor rather than filed down or covered with polish.

Preventing ingrown toenails

Most ingrown toenails come down to three things: nails cut too short, corners trimmed into a curve, and shoes that squeeze the toes. Cutting straight across, leaving a little length and choosing roomy footwear address all three.

• Choose shoes with a toe box wide and deep enough that your toes do not touch the sides or top.
• Make sure socks and tights are not tight across the toes.
• For sport and long walks, check that your toes do not slide forward and strike the front of the shoe.
• Resist the urge to cut out a corner that feels uncomfortable; it usually makes the next one worse.

Between appointments

Moisturise your feet daily, avoiding the spaces between the toes, and massage a little oil into the skin around each nail. If your heels are rough as well, our guide to dry, cracked heels sets out a simple nightly routine.

If you have a gel finish, leave it for proper removal rather than picking at it, as our guide to removing gel polish explains. Clipping through gel can crack it, so if a gel-coated nail needs shortening, file the free edge gently instead.

Questions people ask

How often should I trim my toenails? Usually every few weeks, depending on how quickly they grow. If you have regular pedicures, you may only need to smooth the odd edge in between.

Should toenails be rounded or square? Square with softened corners. A rounded edge on toes encourages the corners to grow into the skin.

Is it fine to use fingernail clippers? They are too small and too curved for most toenails, and they tend to crush rather than cut. Straight-edged toenail clippers are worth having.

Can I clean under the nail with a metal tool? A soft brush is safer. Pushing a sharp tool under the free edge can separate the nail from the skin beneath it.

What if I cannot reach my feet comfortably? Trimming at an awkward angle is how slips happen. A regular pedicure can take care of shaping for you, and if reaching your feet is difficult for health reasons, a podiatrist can take on nail cutting.

When to see a podiatrist

Some things should not be treated at home. See a podiatrist or doctor if a nail is painful, red, swollen or weeping; if it is thickened, discoloured or crumbling; or if a corner is already growing into the skin. If you have diabetes or poor circulation, have your nails cut by a podiatrist rather than trimming them yourself, and check with them before booking any pedicure.

A short checklist

• Trim after a bath, straight across, roughly level with the tip of the toe.
• Use small cuts, then file from the side to the centre.
• Never dig into corners or cut the cuticle.
• Oil the skin around the nail and moisturise the feet daily.
• Wear shoes and socks with room for your toes.
• Stop and see a podiatrist if anything is painful, changed or infected.

For everything else, a regular pedicure takes care of shaping and finish, and how often to book one sets the rhythm.
