The most likely condition is seborrheic dermatitis (seborrhea.) You can suppress this very easily with over the counter 1% hydrocortisone. If that fails, get a prescription for something a bit stronger. Be prepared, however, for having to use this with some regularity, since the condition comes and goes on its own schedule, for no particular reason (soaps and lotions fon't matter, for instance.) See a dermatologist for definitve diagnosis.
Best.
