Hi Olefokes, Malassezia, does your husband have dandruff or Seborrheic dermatitis
? For example, he would have skin lesions, large plaques, or greasy, oily skin, dandruff, itching, redness, and hair-loss? You can have the dermatologist take a look at his skin problem. They may or may not need to do a culture if they can tell by looking at the problem. Does he have a very high temperature or fever? If not it is not likely to be systemic. Malassezia doesn't usually get systemic.
