Psoriasis nail separation: what to know

The detached part may appear white, yellow or opaque because air and debris sit beneath the nail. It can catch on clothing and may gradually extend toward the base. Inflammation from [Nail Psoriasis](/conditions/nail-psoriasis/) can contribute, while [Nail Fungus](/conditions/nail-fungus/) and injury need separate consideration. A photo, examination and sometimes a nail sample help clarify the cause.

Keep the nail short by trimming only the loose edge with clean clippers. Do not tear it off or probe underneath. Keep it dry, wear protective gloves for wet tasks and use footwear with enough room. Avoid polish, glue and artificial nails until the cause is clear. A clinician can advise whether treatment for nail psoriasis or another cause is appropriate.

Seek an appointment if separation is spreading, recurring or joined by thickening, colour change or debris. Get prompt care for pain, pus, swelling, warmth, spreading redness or fever. Significant injury, bleeding or a dark changing streak also warrants timely assessment. [Nail Surgery](/treatments/surgical-dermatology/nail-surgery/) is not a first step for every lifted nail; its role depends on the cause and severity.

Ask whether the lifting pattern fits psoriasis, fungus or trauma, whether testing is needed, and how much of the nail to trim. Ask which warning signs should bring you back sooner.
