Strong nails as you age: what changes and what to do about it

Ageing shows up in all sorts of places, and your nails are no exception. They get thinner, grow more slowly and break more easily — often without you having changed anything.

Here is what changes, and what you can do about it.

What happens to your nails

They get thinner and more brittle

The production of keratin — the protein your nail is made of — slows down over the years. The result is a thinner nail plate that is more prone to cracking and splitting. This is the change most people notice first.

They grow more slowly

Blood circulation to the nail matrix decreases. That is the tissue under your cuticle where new nail cells are formed. Less circulation means slower growth.

This has an annoying side effect: damage repairs more slowly. Where a cracked nail grew out in two months in your twenties, later in life it can take four to six.

Shape and colour change

Nails can thicken, develop more lengthwise ridges and turn more yellow. The natural curve changes too — some nails curve more strongly, others flatten out.

Lengthwise ridges are normal and part of ageing. Horizontal ridges are not: those often point to a period of illness, stress or deficiency. If they keep coming back, get them checked.

What helps most

You cannot reverse ageing, but you can make up for a lot of it. Two habits deliver by far the most.

1. Hydration

This is the most important one. An older nail is primarily a drier nail, and a dry nail is stiff. Stiff nails do not bend along — they break.

Massage nail oil into your nails and cuticles daily. Two minutes, preferably in the evening so it can absorb overnight. A rich hand cream helps too, but oil penetrates the nail plate more deeply.

This is the change people see results from fastest: often within two weeks.

2. Filing instead of clipping

Nail clippers crush the nail edge. On a thin, brittle nail that is exactly where the first crack appears.

Use a fine file and file in one direction. A glass file works well here because it also seals the nail edge, keeping moisture from creeping between the nail layers.

What else helps

• Gloves for cleaning and gardening. Cleaning products dry nails out badly, and an older nail no longer has that reserve.
• Enough protein and iron in your diet. Brittle nails are regularly a sign of iron deficiency.
• A nail hardener if the nail has become genuinely too thin. A hardener with Dimethyl Urea creates extra keratin bonds in the nail you already have — which works faster than waiting for new growth.

When to see a doctor

Most changes are harmless. Do get checked for:

• sudden, strong discolouration of a single nail
• recurring horizontal ridges
• nails separating from the nail bed
• brittleness that persists despite good care

In short

Thinner, slower and drier — that comes with the territory. But most breaks are not caused by the ageing itself, they are caused by the dryness that comes with it. Daily hydration and filing instead of clipping address exactly that, and together they take less than five minutes a day.
