Washing the scalp with vinegar for tinea capitis can only play a minor treatment role and cannot cure it. Tinea capitis is a skin disease caused by fungal infections and requires treatment with antifungal medications. For example, topical application of clotrimazole cream or terbinafine cream can be used, along with antifungal shampoos such as selenium sulfide shampoo or ketoconazole shampoo. Patients with severe tinea capitis may also need oral medication treatment, such as taking itraconazole capsules or terbinafine tablets. It is advisable not to self-medicate tinea capitis, and systematic treatment should be sought at a hospital.
