What is onychomycosis?

Onychomycosis refers specifically to a fungal infection that affects the nails. This condition often manifests as thickened, discolored, or brittle nails, and it can occur in one or more nails. Fungi, such as dermatophytes, yeast, or non-dermatophyte molds, are the primary causative agents. This infection is more common in toenails than fingernails due to the warm and moist environment that the toes often provide, especially within footwear. Understanding onychomycosis is vital for nail technicians because it can impact nail health and aesthetics. Identifying this condition correctly is essential for determining appropriate treatment options, which may include topical or oral antifungal medications.
