Remember the yeast-as-agent-of-cradle-cap theory from a few pages back? Some of the support for that idea comes from the fact that some cradle cap infections respond to antifungal medications.
Topical antifungal drugs you might encounter in your quest to end cradle cap include miconazole (Micatin), clotrimazole (Lotrimin), ketoconazole (Nizarol) and terbinafine solution (Lamisil) [source: Johnson and Nunley].
For adults, there are some medicated shampoos that contain antifungal ingredients such as selenium sulfide, which we mentioned earlier (found in Selsun, Selsun Blue and Exsel). Pyrithione zinc is another preparation that's fungus-unfriendly and also ubiquitous in the dandruff care section of the drugstore. Again, this isn't the kind of step you can (or should) take without a doctor's advice, so make the call.
