Infection caused by Malassezia infection of the scalp

Malassezia Infection Of The Scalp

Malassezia is a type of fungus that lives naturally on the scalp of many individuals. While this fungus is usually harmless, an overgrowth of Malassezia on the scalp can cause an infection known as Malassezia folliculitis. This infection can cause symptoms such as itching and flaking of the scalp, crusty skin lesions, and yellow or white pustules.

In some cases, Malassezia infection of the scalp may cause inflammation and hair loss. People with weakened immune systems, such as individuals with HIV or AIDS, may be more likely to experience an infection caused by Malassezia.

Diagnosis and Treatment of Malassezia Infection
