Final answer:
Ketoconazole is a commonly used brand-name shampoo for treating fungal infections, while other antifungal treatments include clotrimazole and terbinafine.
Step-by-step explanation:
The brand name for a shampoo to treat fungal infections is ketoconazole, often marketed under the brand name Nizoral. Ketoconazole is an antifungal shampoo used to treat infections such as tinea versicolor and dandruff, which are caused by the fungus Malassezia. Moreover, ketoconazole shampoo is also used off-label for the treatment of androgenic alopecia in conjunction with an oral 5α-reductase inhibitor.
Other antifungal medications commonly used for skin infections include clotrimazole and terbinafine. Clotrimazole can be found in creams like Canesten®, which is used to treat various fungal skin conditions. Terbinafine, found in Lamisil, is used topically for infections like athlete's foot, ringworm, and jock itch, with a form for systemic use available for nail fungus treatment.
