Which treatment works the best and fastest for ringworm on the scalp?

Griseofulvin: Tinea is a fungus, and when it occurs on the scalp it is actually called tinea capitus. Tinea corporis, on the body, is called ringworm, because it causes a ring-like rash. Fungus on the scalp is harder to treat than on the body. Rinworm responds to creams, like lamisil, (terbinafine) for about 2 weeks, but the scalp requires an oral medicine, like griseofulvin, and for a longer period of time (6-12 weeks).
