Before diving into treatment options, it’s important to understand what nail fungus is and how it develops. Nail fungus occurs when fungi, including dermatophytes, yeasts, or molds, invade the nail bed through tiny cracks or cuts. It often starts as a small white or yellow spot under the tip of the toenail or fingernail and can spread deeper into the nail if left untreated. https://zanaquick.com/collections/frontpage
