Fungal infections usually occur where within the nail structure?

Fungal infections primarily occur inside the nail plate, which is the hard, keratinized structure that forms the visible part of the nail. The fungi thrive in warm, moist environments, and when they invade the nail plate, they can cause various symptoms, such as discoloration, thickening, and separation from the nail bed.

Moisture trapped under the nail plate or within its layers creates the ideal breeding ground for fungi, making this area particularly vulnerable. While the surface of the nail, the cuticle, and other external areas can be affected by superficial conditions and irritations, fungal infections target the interior for infestation and growth, which is why recognizing their occurrence inside the nail plate is crucial in nail technology practice.
