Toenail fungal infections, also known as onychomycosis, can cause unsightly discoloration, thickening, and crumbling of the toenails. Once the infection has been successfully treated, the process of regrowing a healthy new toenail begins. This process can take several months and involves distinct stages of initial growth, maturing growth, strengthening, and eventual full recovery. Understanding these stages and providing proper nail care during regrowth is crucial for managing expectations and supporting the healing process. With patience and diligent foot hygiene practices, it is possible to regain strong, clear toenails after overcoming a fungal infection.
