Povidone-iodine plus Daktarin cream can treat gray nails, and is suitable for mild gray nails, such as only appearing to become cloudy and brittle locally.
Usually, after cutting the gray nails, you can use iodophor to disinfect them, and then apply dactinomycin to the surface of the affected nails, which can have a certain inhibiting effect on the fungus at the gray nails. After eliminating the fungus, the nail will also grow well gradually.
Severe gray nails, such as thickening of the nails and shrinkage of the nail bed, also need to be treated with oral antifungal drugs. Oral treatment with terbinafine hydrochloride tablets and itraconazole, as well as application of cyclopiroxamine, amorolfine nail rub, ketoconazole ointment, etc., can be used. The treatment of nails usually needs to be used for 3 months, and the treatment cycle of toenails is longer than that of fingernails, which needs to be more than 6 to 9 months.
