Nail fungus, also known as onychomycosis, is a persistent and contagious condition. It can be treated through various methods, depending on its type and severity. One of the most effective and convenient treatments for nail fungus is ND-YAG laser therapy, which penetrates the different layers of the nail to kill or destroy the fungal cells, especially when used concurrently with an antifungal medication. However, in more severe cases, other treatments, such as surgery, may be necessary.
