Why Are My Nails So Brittle (And What You Can Do To Help Them)?

Why Are My Nails So Brittle (And What You Can Do To Help Them)?

If your nails snap easily, peel at the edges or feel thin and fragile, you are likely dealing with brittle nails. It can be frustrating, especially if you are trying to grow your nails or keep them looking neat. The good news is that brittle nails have clear causes and, with the right routine, can be improved significantly.

Here is your full guide to why your nails may be brittle and the practical steps you can take to strengthen them.

1. Your Nails May Be Dehydrated

Dehydration is one of the most common reasons for brittle, easily broken nails.

How dehydration affects nails:

1. The nail plate becomes rigid and fragile.

2. Layers of keratin separate, causing peeling.

3. Nails lose flexibility and snap under pressure.
   

How to improve hydration:

1. Apply cuticle oil at least twice a day.

2. Use hand cream frequently throughout the day.

3. Avoid harsh hand sanitisers where possible.

4. Use gloves when cleaning or washing dishes.
   

2. Your Nails May Be Overexposed to Water

Water makes nails soft and swollen, but once they dry they shrink again. This continuous swelling and shrinking weakens the structure of the nail.

Common sources of excess water exposure:
Frequent hand washing
Long baths
Swimming
Cleaning without gloves

How to protect your nails:

1. Wear gloves for all cleaning and household tasks.

2. Reduce soaking your hands in water.

3. Moisturise immediately after washing your hands.
   

3. Incorrect Gel or BIAB Removal Can Cause Brittleness

Peeling or picking off enhancements takes layers off the natural nail, leaving it thin, rough and breakable.

Signs of incorrect removal:
Peeling at the free edge
White patches on the nail surface
Thin, bendy nails
Soreness after removal

How to prevent further damage:

1. Always book a professional removal.

2. Never pick or peel off gel polish, BIAB or extensions.

3. Keep nails short while they recover.

4. Consider a strengthening BIAB overlay to protect the damaged nail.
   

4. Over-Filing Can Thin the Nail Plate

Heavy-handed filing at home or from inexperienced technicians can cause long-term brittleness.

Why over-filing causes problems:

1. It removes protective layers from the nail surface.

2. Nails become thin, sensitive and prone to splitting.

3. Recovery can take several months.
   

What to do:

1. File only in one direction using a 180-grit file.

2. Avoid DIY electric files completely.

3. Let your technician shape and refine your nails professionally.
   

5. A Lack of Essential Nutrients Can Lead to Brittle Nails

Healthy nails require a range of vitamins and minerals. Without them, nails may grow weak or soft.

Nutrients that support nail strength:
Biotin
Zinc
Iron
Protein
Omega-3
Vitamin C and E

How to support your nail health:

1. Eat a varied diet with leafy greens, fish, eggs and nuts.

2. Stay well hydrated.

3. Avoid extreme dieting which slows nail growth.

4. Speak to a GP if you suspect a deficiency.
   

6. Ageing Can Naturally Make Nails More Brittle

As we age, the nail plate produces fewer natural oils. This causes dryness and reduced flexibility.

How to support ageing nails:

1. Increase the use of cuticle oil.

2. Moisturise hands more frequently.

3. Keep nails shorter for added strength.

4. Use smoothing and strengthening products such as BIAB.
   

7. Chemicals and Harsh Products Can Break Down Nail Health

Cleaning agents, low-quality nail polish removers and certain sanitising products can contribute to brittleness.

How chemicals affect nails:

1. They strip oils from the nail plate.

2. They dry out the surrounding skin.

3. They lead to peeling and breakage.
   

How to protect your nails:

1. Wear gloves when cleaning or using harsh products.

2. Use non-acetone remover where appropriate.

3. Moisturise immediately after using any chemicals.
   

8. Cold Weather and Low Humidity Can Weaken Nails

During winter, nails lose moisture quickly and become more brittle.

What to do:

1. Increase cuticle oil application.

2. Use a thicker hand cream overnight.

3. Wear gloves outside in cold weather.

4. Maintain regular salon appointments for professional care.
   

9. Certain Medical Conditions May Influence Nail Brittleness

Although far less common, some nail brittleness may be linked to underlying conditions.

Possible contributors:
Thyroid conditions
Anaemia
Psoriasis
Eczema
Circulation issues

When to seek advice:
If all nails suddenly change or weaken rapidly, speak to a healthcare professional for reassurance.
