There is no easiest way to treat gray nails and the treatment needs to be chosen based on the patient’s condition. Gray nails, also known as onychomycosis, are caused by dermatophytes that invade the nails or subnail tissues. When the symptoms are mild, you can use medication, such as oral antifungal drugs such as itraconazole tablets, or local application of topical drugs such as amorolfine ointment, but the effect of the medication varies greatly from individual to individual. If the effect of medication is not good, the duration of the disease is relatively long, or the patient’s condition worsens, such as damage to the distal nail plate, the emergence of ingrown nails, etc., can be performed nail removal treatment. It is recommended to consult a doctor in time and follow the doctor’s instructions.
