How to fix brittle nails

Brittle nails may split, peel in layers, crack at the edge or break with ordinary use. Frequent hand washing, prolonged soaking, detergents, nail polish remover and filing in both directions can strip moisture and weaken the nail plate. Picking at polish or biting the nails adds small injuries. A fungal nail infection can also change colour, thickness or texture, especially when one or more nails become crumbly or lift from the nail bed.

Keep nails short and smooth rough edges with a fine file, using strokes in one direction. Wear protective gloves for dishwashing or cleaning, and dry hands and the skin around each nail afterwards. Apply a thick hand or nail moisturiser after washing and before bed. Avoid cutting or pushing back cuticles, and give nails a break from extensions, hardeners and frequent remover. Do not share nail tools; clean personal tools after use. A clinician can examine discolouration, thickening or lifting and decide whether testing for Nail Fungus is appropriate.

Arrange a dermatology assessment if a nail becomes painful, swollen, very tender, discoloured, thickened or separated from the skin, or if several nails change without an obvious cause. Prompt care is sensible for redness spreading around a nail, drainage, or a new dark streak. A sudden change after an injury also deserves review, particularly when the colour does not grow out with the nail.

Ask whether the pattern fits dryness or irritation, whether a nail sample is needed, and which moisturiser or protective routine suits your work. Mention new medicines, skin rashes, hair changes, dietary restrictions and any use of gels or extensions, because these details can help narrow the cause.
