🦠

Nail fungus (onychomycosis) is a common but stubborn infection caused by fungi that invade the nail bed, leading to thick, discolored, brittle nails. It is notoriously hard to treat because:

• Fungi grow slowly and are protected under the thick nail plate, making topical treatments less effective.
• Reinfection is common, especially in people with poor circulation, diabetes, or weak immune systems.
• Fungal spores persist in shoes, socks, and showers, making relapse likely.
