How to Keep Your Nails Healthy: Tips That Actually Work

Keep your nails healthy and they will reward you with strength, flexibility, and a natural shine that no polish can replicate. Neglect them and you end up with peeling, splitting, and brittleness that makes even the best manicure look rough.

We spoke to nail technicians and dermatologists to compile practical advice that actually works, cutting through the marketing noise around nail care products.

Why Nail Health Matters More Than You Think

Your nails are made of keratin – the same protein found in hair and skin. Their condition reflects your overall health, with changes in colour, texture, or growth patterns sometimes indicating nutritional deficiencies or underlying health issues.

Beyond health signals, strong nails simply make daily life easier. If you have ever struggled to open a can, type comfortably, or apply a contact lens because of a torn nail, you understand the practical value of keeping them in good condition.

Daily Habits for Stronger Nails

Moisturise Your Cuticles

Dry cuticles lead to hangnails, cracking, and infection. Apply a cuticle oil or even plain olive oil nightly before bed. The oil keeps the cuticle soft and flexible, which supports healthy nail growth from the matrix underneath.

Wear Gloves for Cleaning

Household cleaning products, particularly those containing bleach or strong detergents, strip moisture from nails and weaken them over time. Wearing rubber gloves while washing up or cleaning is one of the simplest and most effective things you can do.

Keep Nails at a Practical Length

Very long nails are more prone to snagging, breaking, and harbouring bacteria. A moderate length that extends slightly beyond the fingertip offers the best balance of appearance and resilience. File nails in one direction rather than sawing back and forth, which causes splitting.

What to Eat for Healthy Nails

Nail strength starts from the inside. Biotin, found in eggs, almonds, and sweet potatoes, supports keratin production. Iron from red meat, spinach, and lentils prevents the spoon-shaped nails associated with iron deficiency anaemia.

Zinc from shellfish, chickpeas, and pumpkin seeds supports cell division and growth. Omega-3 fatty acids from oily fish and flaxseed keep nails hydrated and flexible. A balanced diet covers most bases, but a biotin supplement can help if your nails are persistently weak.

Common Mistakes That Damage Nails

Using Nails as Tools

Prying open lids, peeling off stickers, or scratching at surfaces with your nails causes micro-damage that accumulates over time. Use a proper tool instead – your nails will thank you.

Overusing Gel and Acrylic

Gel and acrylic manicures look fantastic but the removal process, particularly scraping and soaking in acetone, can thin and weaken the nail plate. Give your nails regular breaks between treatments – at least two to three weeks of bare nails allows them to recover.

Cutting Cuticles

Despite what some salons still do, cutting cuticles is not recommended by dermatologists. The cuticle acts as a seal against bacteria and fungi. Push them back gently with an orangewood stick after a shower instead.

Best Nail Care Products Worth Buying

You do not need dozens of products. A good cuticle oil, a glass nail file, a nourishing base coat, and a gentle non-acetone remover cover the essentials. Sally Hansen Hard As Nails is a reliable strengthening treatment available at most chemists.

For cuticle oil, CND Solar Oil is the industry standard used in professional salons. A glass file is a one-time investment that seals the nail edge more effectively than emery boards and lasts indefinitely with proper care.

When to See a Doctor

Most nail issues are cosmetic, but some changes warrant medical attention. See your GP if you notice persistent discolouration, particularly dark streaks running lengthwise. Nails that separate from the nail bed, significant changes in shape, or nails that become unusually thick or crumbly should also be assessed.

Fungal nail infections are common and treatable but need proper diagnosis. Over-the-counter treatments work for mild cases, while more stubborn infections may require prescription medication.

Frequently Asked Questions

How do I keep my nails healthy and strong?

Moisturise cuticles daily, wear gloves when cleaning, eat a balanced diet rich in biotin and iron, file in one direction, and give nails regular breaks from gel or acrylic treatments.

What vitamin is best for nails?

Biotin is the most researched vitamin for nail health and has been shown to improve nail thickness and reduce splitting. It is found naturally in eggs, nuts, and sweet potatoes, or can be taken as a supplement.

Why do my nails keep breaking?

Common causes include dehydration, frequent exposure to water or chemicals, nutritional deficiencies, and damage from gel or acrylic removal. Addressing the underlying cause is more effective than simply using strengthening polish.

How often should I cut my nails?

Fingernails grow approximately three to four millimetres per month. Trimming every one to two weeks keeps them at a manageable length. Use sharp nail clippers and follow up with a glass file to smooth the edges.
