Tinea versicolor is one of the most common types of ringworm and can be treated with bifenazole cream once a day for 1 month. Tinea capitis, or hand fungus, is the most common superficial fungal infection of the hands. There are three common types, the blister type, the scaly keratosis type, and the interscrub type (also called erosions). Among them, the blister type is relatively mild, manifesting as small blisters that do not break easily, and when the blister walls are torn open, the skin base is bright red vesicles, often accompanied by itching. Treatment should be with a less irritating water or cream, such as terbinafine spray, bifenazole cream, or ketoconazole cream, and adhered to for 4-8 weeks, with consolidation of treatment after the rash subsides to prevent recurrence. If you have tinea pedis, you should treat it at the same time to avoid auto-transmission. If the nails of hands and toes show yellowing, thickening and cloudiness, consider combined nail fungus, i.e., gray nail, which is difficult to cure with topical medication alone. It is recommended to take itraconazole capsules orally (4-5 courses of 1 month each, 1 week of medication, 2 capsules of itraconazole capsules at lunch and 2 capsules at dinner, no alcohol during medication, eat more fat-rich food, and monitor liver function during medication) for impact therapy. Tinea capitis often occurs on one hand and should be differentiated from hand eczema (which occurs symmetrically on both hands), which is treated in different directions.
