How to stop nails splitting

Nails may peel or split when the nail plate repeatedly absorbs water and then dries, or after contact with detergents, solvents, polish remover, or vigorous filing. Biting, picking, and using nails as tools can add small breaks. One or several nails may be affected. Thickening, yellow or white discolouration, debris beneath the nail, tenderness, or separation from the nail bed can point to a condition such as nail fungus and deserves an examination.

Trim nails straight across with clean clippers and smooth only rough edges with a fine file. Apply a plain moisturiser or ointment to the nail plate and surrounding skin after handwashing. Use protective gloves for washing dishes, cleaning, and prolonged water exposure; let sweat dry inside gloves by taking breaks. Avoid peeling layers off, cutting cuticles, harsh buffing, and acetone-heavy remover. Give damaged nails time to grow out, and mention medicines, skin conditions, or dietary restrictions to a clinician if the problem keeps returning.

Arrange a dermatology review for persistent splitting, changes limited to one nail, marked thickening, colour change, pain, swelling, drainage, or a nail lifting from its bed. Prompt care is appropriate when redness spreads around the nail, or when an injury causes severe pain or dark discolouration. A clinician can distinguish mechanical damage from conditions such as Nail Fungus and choose treatment safely.

Could a fungal infection, eczema, psoriasis, medication, or another cause explain the nail change? Should the nail be tested before treatment? Which moisturiser and protective routine suit my work and handwashing habits?
