Why cuticle care changes how your nails grow

Cuticle care matters because the cuticle is a seal over the matrix, the spot under the skin where every new millimetre of nail is made. A dry, cracked or cut cuticle can show up weeks later as ridges, dents and weaker growth. The rules are simple: never cut it, push it back gently only when it is soft, and oil it every day so it stays sealed.

  • The cuticle seals the spot where new nail is made, so what happens to it shows in the nail weeks later.
  • Never cut it. Push it back gently, and only when it is soft.
  • Oil it every day. Most people notice softer cuticles within days.
  • Hangnails get trimmed cleanly, not pulled.

What are the cuticle and the eponychium?

The cuticle is the thin, clear layer of dead skin that clings to the base of your nail, and the eponychium is the living fold of skin it grows from.

Most people call the whole lot "the cuticle", and I will too from here, but the difference matters when you are deciding what to trim and what to leave alone. Under that skin sits the matrix, where all of your nail is made, and the cuticle is the seal that keeps that spot closed off from water and dirt. It's a bit like the rubber seal round a window: you only notice it when it fails.

Why does cutting your cuticles backfire?

Cutting backfires because it removes the seal and leaves tiny cuts right next to the place new nail is made.

The skin is left ragged, a ragged edge catches and tears, and a tear is a hangnail waiting to happen. That is the cycle behind a lot of sore, rough nail edges: tidy, trim, tear, tidy again. I know the neat little strip coming off feels satisfying, but it's the start of the loop.

My rule is short. The scissors stay in the drawer and the oil goes in the handbag.

How do you push your cuticles back safely?

Push your cuticles back only when they are soft, and only gently, because a dry cuticle pushed hard cracks instead of moving.

  1. Soften first. Do it straight after a warm shower, or after you have oiled.
  2. Use something gentle. Your thumb through a towel works, or a rubber tipped pusher, or the rounded end of an orangewood stick.
  3. Light pressure, small movements. You are moving skin, not scraping the nail.
  4. Stop at the first sting or any redness. Sore skin needs leaving alone, not more attention.
  5. Oil afterwards. That puts the seal back in good order.

If you only keep one of those, keep the first. Soft skin moves, and dry skin tears.

How often should you oil your cuticles?

Oil your cuticles every day, and most people notice softer cuticles within days.

Put a little on the cuticle, the skin at the sides of the nail and the nail itself, then rub it in. While your nails and cuticles are recovering from damage, I'd oil twice a day, morning and night.

I used my serum on my own clients for years before I offered it to anyone else, and the pen is the easiest way to keep this habit going: the Nail Growth and Strength Serum pen. One click covers all ten nails. If you want help choosing a cuticle oil, start with the best cuticle oil in Australia.

Within days
Most people notice softer cuticles.
One to two weeks
Most people notice visible growth. Results vary.
Two to three months
The nail you can see was made two to three months ago, so this is when the nail made under a better cared for cuticle starts to reach the tip.
Four to six months
A full new fingernail has grown through.

What does a dry cuticle do to your nail later?

A dry, cracked or cut cuticle can show up in the nail weeks later as ridges, dents or weaker growth, because the nail is made under that skin and what happens there shows when the nail grows out.

A fingernail grows about 3 mm a month, so there is always a delay between the cause and the result. That delay works in your favour too. Look after the cuticle now and the nail made under it comes through better, though you will wait for it to reach the tip, and I won't pretend that wait is exciting.

Do

  • Oil every day.
  • Push back only when soft.
  • Oil again after hand washing when you can.

Don't

  • Cut the cuticle.
  • Push it back when it is dry.
  • Pick or bite the skin beside the nail.

What do you do about hangnails?

A hangnail is a torn strip of dry skin at the side of the nail, and pulling it tears more of it, so trim it cleanly instead.

Use sharp, clean clippers, snip only the lifted piece, and oil afterwards. Picking and biting keep the skin sore, and sore skin invites more picking, so give your hands something else to do.

When should you see a doctor?

See a doctor when the skin around the nail is red, swollen, throbbing or changing, because that is a different problem from dry and ragged cuticles.

Dry and ragged is a habit problem, and a habit is something you can change.

If it came on suddenly, hurts, is discoloured, thickened or lifting, see a GP, dermatologist or podiatrist.

Questions people ask

How often should you use cuticle oil?

Every day is a good habit, and twice a day is fine while your nails and cuticles are recovering from damage. One click of the pen covers all ten nails. Most people notice softer cuticles within days. Put a little on the cuticle and the skin at the sides of the nail, then rub it in until it has gone.

Should you cut your cuticles?

No, I would not cut your cuticles, because the cuticle seals the spot where new nail is made and cutting it leaves the skin ragged and the seal open. Push it back gently when it is soft, oil it daily, and trim only a lifted piece of dead skin, a hangnail, with clean, sharp clippers.

What is cuticle oil for?

Cuticle oil keeps the skin around the nail soft and hydrated, so it stays sealed instead of cracking, tearing and catching. It also helps the nail itself stay flexible. Softer cuticles and fewer tears mean you keep more of the length you grow.
