What should you know about fungus from nail salon?

Nail fungus can cause yellow, white, or brown discolouration, thickening, crumbling, lifting, or debris beneath the nail. A salon service can also injure the nail plate or surrounding skin, and artificial products may conceal early changes. Athlete's foot can coexist with nail fungus and may spread between feet, socks, shoes, and nails. Because several conditions look alike, a clinician may clip or scrape the nail for testing.

Pause polish, extensions, and aggressive filing until the nail is assessed. Keep nails short and dry, use clean personal tools, and do not share files, clippers, socks, or towels. Avoid pulling off a lifting nail. If testing confirms infection, treatment may involve topical antifungal treatment, oral antifungal treatment, laser treatment, or nail surgery in selected situations.

Book a review if discolouration persists, spreads to other nails, or is joined by thickening or lifting. Seek prompt care for redness, warmth, swelling, pus, or worsening pain around the nail. People with diabetes, poor circulation, reduced immunity, or repeated foot infections should arrange assessment early rather than self-treating.

Ask whether the nail needs laboratory confirmation, whether the salon service caused trauma, which treatment fits the number and location of affected nails, and how to protect nearby skin. Ask when polish or salon services can safely resume and how long monitoring will take.
