How Do I Repair Broken, Weak Nails?
Why do nails become weak or break?
If your nails keep splitting, peeling, or snapping, you’re not alone. Brittle nails are common — affecting roughly 1 in 5 adults, with higher rates in women and older adults according to European dermatology studies. It’s rarely just “bad luck” — usually it’s a mix of treatments, habits, and sometimes health.
Top culprits
-
Gel, shellac & acrylics — repeated buffing/drilling and acetone soaks dry the nail plate.
-
Acetone removers — strip natural oils and increase brittleness.
-
Dipping powders — strong adhesives and soak-off/removal can be harsh.
-
Frequent polish cycles — solvents + pigments may dehydrate/stain.
-
Everyday life — water, detergents, cleaning, cold weather, ageing.
-
Medical & nutritional factors — iron deficiency, thyroid issues, low protein/biotin/zinc; some medicines.
The science (quick + friendly)
Your nails are made of stacked keratin layers. When natural oils and water balance are stripped (think acetone, aggressive filing, or constant wet-dry cycles), those layers separate — hello peeling, cracking, splitting. Keep the keratin flexible and protected, and nails stay strong and glossy.
How to repair and strengthen weak nails
1) Short-term rescue
-
Trim & shape short — fewer snags = fewer breaks.
-
Daily hydration — cuticle oil/hand cream (jojoba, almond, vitamin E) to restore flexibility.
-
Acetone-free remover — gentler on keratin when you do remove colour.
-
Moisturise after washing — water paradoxically dries nails; lock moisture back in.
2) Lifestyle that protects nails
-
Gloves on for washing up, cleaning, gardening.
-
Be kind to tips — use tools, not nails, to open things.
-
File in one direction with a fine grit; avoid sawing back and forth.
3) Nourish from the inside
-
Protein for keratin (aim for a serving with each meal).
-
Iron & zinc (meat, legumes, leafy greens, seeds).
-
Biotin from food (eggs, nuts, pulses); supplements only if advised by a clinician.
-
Hydration — dehydration shows up in nails too.
4) Recovering from gels/acrylics/dips
-
Take breaks between salon systems; avoid back-to-back sets.
-
Don’t pick or peel — it removes surface layers of nail.
-
Switch to gentler colour: consider wraps for shine without drilling or long acetone soaks.
A gentler alternative for colour and shine
We’re biased, but for good reason: modern nail wraps deliver gel-like gloss with kinder removal (oil/remover, no marathon acetone). They’re a smart way to look polished while you let nails recover.
mesme promise: Our wraps — including UV — are formulated without TPO and aligned with current EU/CH regulations. Because fabulous should be fearless.
When to see a doctor
Book a GP/dermatologist if you notice:
-
Persistent splitting/peeling despite protective care
-
Discolouration, thickening, or pain
-
Pitting or ridging with skin changes (could signal psoriasis/eczema)
-
Sudden changes after new medication or illness
These can point to fungal infection, psoriasis, thyroid or nutritional issues — all treatable with the right care.
