Psoriasis nail repair: what to know

Inflammation around the nail matrix or nail bed can cause pits, ridges, thickening, separation and debris beneath the nail. Because the visible nail grows slowly, improvement usually follows new growth rather than an instant surface change. A damaged nail can also be affected by repeated knocks, moisture or infection, so the appearance should guide an examination rather than a cosmetic repair alone.

Cut nails short, smooth sharp edges and avoid removing attached nail material. Keep hands and feet dry after washing, use gloves for cleaning and choose shoes that do not press on toenails. Do not apply glue, acrylics or strong removers to a tender or lifting nail without professional advice. A clinician can discuss treatments for nail psoriasis and check nearby [Dry Skin](/symptoms/dry-skin/) or [Cracked Skin](/symptoms/skin-cracking/).

Book a review when damage persists, affects daily tasks or involves pain, swelling, drainage or increasing separation. Prompt care is appropriate for spreading redness, warmth or fever. A sudden change after trauma, or a dark mark that changes or reaches the surrounding skin, should also be examined.

Ask what part of the nail is inflamed, whether infection should be checked, and how long a treatment trial should be followed. Ask how to cover or trim the nail safely while it grows.
