How can dry, brittle nails improve?

Nails may split, peel, or crack after repeated cycles of soaking and drying, frequent handwashing, detergents, solvents, manicures, or picking. Trauma can affect one nail, while changes affecting several nails may reflect eczema, psoriasis, nutritional problems, medication effects, or another medical issue.

Fungal nail infection is one possible cause, but brittle nails do not by themselves confirm it. Discolouration, thickening, debris beneath the nail, or separation from the nail bed should be examined rather than treated blindly.

Wear gloves for cleaning and prolonged wet work, dry hands thoroughly, and apply a thick moisturiser to the nails and surrounding skin after washing. Keep nails at a practical length, file rough edges in one direction, and avoid biting, picking, harsh removers, and aggressive cuticle work. Pause artificial nails if the natural nail is lifting or sore.

A clinician can check for infection or skin disease and may arrange tests when the pattern suggests a broader cause. Read about [Nail Fungus](/conditions/nail-fungus/) if thickening or debris is present, but avoid sharing prescription treatments.

Book an assessment for persistent changes, pain, swelling, pus, bleeding, a nail separating from its bed, or a new dark streak. Prompt review is especially sensible when several nails change together or when nail changes occur with fatigue, rash, or joint symptoms. Sudden severe swelling or spreading redness needs urgent care.

Could this be fungal infection, eczema, psoriasis, or repeated trauma? Do I need a nail sample or blood tests? Which moisturiser and protective routine fit my work? Should I stop manicures or artificial nails while the nail grows out?
