Nail extraction is the surgical removal of the entire nail, which removes the fungus-infected diseased nail and is theoretically effective. However, nail extraction is not currently recommended for the treatment of gray nails, as it is a very painful operation, and there are other better ways to treat gray nails, such as antifungal treatment protocols, oral antifungal medication, and topical antifungal treatment protocols for nail fungus. Therefore, nail extraction alone is not currently recommended for the treatment of gray nails. In addition, nail extraction is not only painful, but after the nail is removed, the new nail may be smaller than the original nail, making it more likely to cause ingrown nails and can affect the aesthetics.
