What are the signs of a fungal nail infection?

A fungal nail infection typically presents with specific characteristics that differentiate it from other types of nail conditions. Discoloration, thickening, and brittleness of the nail are hallmark signs of this type of infection. The discoloration can manifest as yellow, white, or even brown areas on the nail due to the accumulation of the fungus. As the infection progresses, the affected nail often becomes thicker and more brittle, leading to a rough texture and potential crumbling at the edges, which can also lead to discomfort.

These symptoms are crucial for a nail technician to recognize, as they indicate a need for careful handling and potentially a referral to a healthcare professional for treatment. Recognizing these signs helps in preventing the spread of the fungal infection to other nails or individuals. In contrast, while excessive nail growth, redness, swelling, and pain could be associated with other nail conditions or injuries, they are not specific indicators of a fungal infection.
