Onycholysis from gel nails

Onycholysis creates a space under the nail plate. With gel manicures, filing can thin the surface, a close-fitting product can pull at the edge, and peeling can remove layers of natural nail. Product touching the surrounding skin may cause irritation or allergy, while moisture beneath a lifting coating can support infection. Yellow or green colour, thickening, debris, or changes in several nails deserve an examination because Nail Fungus and Nail Psoriasis can look similar.

Do not peel or pick gel from a lifting nail. Have remaining product removed gently, then leave the natural nail bare, short, and dry. Avoid repeated soaking, harsh filing, cuticle cutting, and another gel set until the nail and surrounding skin have settled. Wear protective gloves for cleaning and dry beneath the nail after handwashing. Keep personal files and clippers separate. A clinician can assess the nail before recommending treatment; [Nail Surgery](/treatments/surgical-dermatology/nail-surgery/) may be considered only for specific problems.

Arrange a review if the detached area continues to advance, returns after each manicure, or involves other nails. Seek prompt care for tenderness that is increasing, redness, warmth, swelling, pus, bad odour, bleeding, or a dark mark without a clear injury. A widespread rash, facial swelling, or breathing difficulty after gel exposure requires urgent attention.

Does the pattern fit product trauma, allergy, fungus, or psoriasis? Should testing be done? What removal and nail-care routine will reduce further lifting?
