What Is Actually Happening When Your Nails Break
A fingernail is composed of keratin layers. The nail plate is the visible hard surface. The nail bed is the skin beneath. The cuticle is the thin overlapping skin at the base.
When nails break, peel or split, one of three things is happening: the nail plate is dehydrated, the cuticle is damaged and no longer sealing the nail base, or the free edge is filing-weakened.
Common nail problems by cause:
| Problem | Cause | Fix |
|---|---|---|
| Peeling layers | Dehydration; incorrect gel removal | Cuticle oil daily; soak-off removal only |
| Splitting at tips | Brittle nails from lack of moisture | Biotin supplement; strengthening topcoat |
| Slow growth | Nutritional gap | Biotin, iron, zinc |
| White spots | Impact trauma to nail matrix | Grow out; no treatment speeds this |
| Vertical ridges | Normal ageing; nutrition | Ridge-filling base coat |
| Yellowing | Staining from dark polish | Always use base coat |
Filing: The Correct Method
Sawing back and forth with a nail file creates micro-fractures that cause peeling within days. Always file in one direction, from the outer edge toward the centre.
File grit by use:
- 240-grit: Natural nails in good condition
- 180-grit: Standard natural nail shaping
- 150-grit and below: Artificial nails only; too abrasive for natural nails
Shape risk levels:
| Shape | Breakage Risk | Suitable For |
|---|---|---|
| Round or oval | Low | All nail lengths |
| Squoval | Low to medium | Medium length |
| Square | Medium | Long nails with strong free edge |
| Almond | Medium | Medium to long |
| Stiletto or coffin | High | Extensions only |
The At-Home Manicure Sequence That Lasts
Step 1: Remove old polish completely.
Soak a cotton pad in acetone-free remover for regular polish. Press and hold for 10 seconds, then wipe. Do not rub in circles.
Step 2: File dry nails.
Never file wet or freshly bathed nails. Wet nails are softer and split more easily when filed.
Step 3: Push back cuticles, do not cut.
Soak fingers for 3 minutes. Use a rubber cuticle pusher to gently push the cuticle back. Cutting cuticles creates entry points for bacteria and causes them to grow back thicker.
Step 4: Buff lightly.
One or two strokes of a 4-way buffer removes ridges and creates adhesion texture. Over-buffing thins the nail plate over time.
Step 5: Wipe with alcohol.
Acetone wipe or 70% isopropyl alcohol removes all oil from the nail surface. Residual oil is the number one cause of polish lifting.
Step 6: Apply base coat.
Base coat protects from staining, creates adhesion and strengthens. Apply one thin coat and cap the free edge (swipe across the tip). Allow 60 seconds before applying colour.

Thin coats dry faster, adhere better and do not shrink-peel as thick coats do.
Application technique: Remove excess polish on the bottle neck. Apply a thin stripe down the centre first, then two stripes on either side. Cap the free edge after each coat. Allow 2 minutes between coats.
Step 8: Apply topcoat.
One coat of topcoat extends wear by 3 to 5 days. Cap the free edge. Reapply topcoat every 2 to 3 days to maintain the seal.
Step 9: Cuticle oil immediately after.
Apply cuticle oil to the surrounding skin and nail plate. Cuticle oil penetrates through the polish and nourishes the nail from the sides and base.
Gel Polish at Home Without a Salon
A basic LED lamp costs £15 to £35 and cures gel in 30 to 60 seconds per coat.
At-home gel sequence:
- Prep as above (alcohol wipe is critical for gel adhesion)
- Apply gel base coat; cure 30 to 60 seconds
- Apply thin gel colour coat; cure; repeat for second coat
- Apply gel topcoat; cure 60 seconds
- Wipe with alcohol wipe to remove the tacky inhibition layer
The most important gel rule: Never peel gel polish. Peeling removes layers of the natural nail plate. Soak cotton pads in acetone, press to nails, wrap in foil and wait 12 to 15 minutes. Slide the softened gel off gently with a wooden stick.
