What should you know about nail separating from the nail bed?

The lifted area may look white because air has entered beneath the nail. A fungal infection can also cause thickening, crumbling, or colour change, while trauma, tight footwear, manicures, and irritants can loosen the nail. Athlete's Foot can spread to toenails. Psoriasis may affect nails as well as surrounding skin. The appearance alone cannot confirm which explanation applies.

Keep the nail clean and dry, trim only the detached edge with clean clippers, and avoid pulling it off. Wear roomy shoes and use gloves for prolonged contact with water or cleaning products. Do not place adhesive under the lifted nail or share nail tools. A clinician may examine nail clippings or nearby skin before recommending topical or oral antifungal treatment. Read more about Nail Fungus and Discoloured Nails if those changes are present.

Arrange a medical review if separation is spreading, affects several nails, keeps returning, or comes with thickening or debris. Seek prompt care for increasing pain, warmth, swelling, pus, fever, or a dark mark that does not grow out with the nail. People with diabetes, poor circulation, or reduced immunity should arrange assessment early after a nail injury or new separation.

Ask whether the pattern suggests injury, Nail Fungus, or another nail condition; whether testing is needed; which nail-care habits could be contributing; and whether Topical Antifungal Treatment, Oral Antifungal Treatment, Laser Treatment For Nail Fungus, or Nail Surgery is appropriate.
