What to Do If Your Nails Are Brittle
Last updated: 3 August 2025
Step 1: Keep Nails Hydrated
Dryness is one of the main causes of brittle nails. Apply hand cream and cuticle oil daily to keep nails and surrounding skin moisturised. Products with ingredients like shea butter, vitamin E, and jojoba oil are especially helpful.
Step 2: Avoid Overexposure to Water
Frequent wetting and drying can weaken nails. Wear gloves when doing dishes, cleaning, or working with water. Avoid soaking your hands for long periods, such as in baths or hot tubs.
Step 3: Minimise Use of Harsh Products
Nail polish remover, especially those with acetone, can dry and damage nails. Choose acetone-free removers and give your nails a break between manicures. Limit exposure to strong cleaning chemicals by using gloves.
Step 4: Trim and File Nails Regularly
Keeping nails neatly trimmed helps prevent splitting and breakage. Use a soft nail file (not a metal one) and file in one direction rather than back and forth to avoid weakening the nail.
Step 5: Strengthen from the Inside
A balanced diet rich in biotin, iron, protein, and zinc supports healthy nail growth. You can also consider a biotin supplement — many people report stronger nails within 3–6 months of consistent use.
Step 6: Avoid Nail-Biting or Picking
Biting your nails or picking at polish can damage the nail plate and lead to weakness. Try using a bitter-tasting nail treatment to discourage biting if needed.
Step 7: Be Cautious with Nail Enhancements
Acrylics, gels, and other enhancements can look great but often leave nails thinner and more brittle afterward. If you use them, ensure you go to a reputable salon and take breaks to allow your nails to recover.
When to See a GP
If your brittle nails don’t improve with care or are accompanied by other symptoms (like fatigue, hair loss, or skin changes), speak to your GP. Brittle nails can sometimes be a sign of iron deficiency, thyroid problems, or other health conditions.
