Pityrosporum (Malassezia) folliculitis happens when yeast that occurs as part of your skin’s natural flora multiplies and infects the hair follicles. The condition causes itchy pimples to form on your face, scalp and upper body. Healthcare providers treat this fungal infection with topical and systemic antifungal medications.
Malassezia (mah-luh-SEE-zee-uh) or Pityrosporum folliculitis (pity-RAH-spur-uhm fuh-lihk-you-LIE-tiss) is a fungal infection that causes bumps to form on your skin. Microorganisms (flora) that normally live on your skin include a yeast called Malassezia. When too much Malassezia grows and gets into your hair follicles, pityrosporum (Malassezia) folliculitis may develop.

You're at higher risk for developing pityrosporum folliculitis if you're an adolescent or were assigned male at birth. You may also be at higher risk if you:
Pityrosporum folliculitis is a common type of dermatitis, a skin condition. It’s hard to know just how common because it doesn’t always require treatment and can be misdiagnosed as acne.
Pityrosporum folliculitis is also called Malassezia folliculitis.
You might get pityrosporum folliculitis on your:
Both conditions cause bumps to appear on your face, scalp and upper body. But the causes are different, and the bumps may look different.
A yeast called Malassezia (pityrosporum) causes this condition. When too much of this yeast grows on your skin and gets into your hair follicles, it causes a fungal infection.
The main symptom of pityrosporum folliculitis is a breakout of itchy bumps. The bumps are usually the same size and shape.
Pityrosporum folliculitis may be contagious. It can be spread through shared razors and hot tubs or, less likely, through skin-to-skin contact between people.
To confirm a diagnosis of pityrosporum folliculitis, your provider may gently scrape your skin to gather some skin cells. They examine these cells under a microscope to look for signs of excess Malassezia yeast. If needed, your provider may do a skin biopsy.
If needed, healthcare providers will treat pityrosporum folliculitis with antifungals. They may start with an antifungal cream (topical treatment) to reduce the amount of yeast on your skin.
When pityrosporum folliculitis is severe or doesn’t go away, your healthcare provider may prescribe antifungal pills (systemic treatment). These include antifungal drugs such as fluconazole (Diflucan®) or ketoconazole.
Some healthcare providers may recommend photodynamic therapy.
You might find relief by using an anti-dandruff (selenium sulfide) shampoo or OTC antifungals for the treatment of fungal infections (like athlete’s foot) on your skin.
An herbal supplement called tea tree oil may help with pityrosporum folliculitis. Talk with your healthcare provider about whether tea tree oil is right for you.
Oral antifungal medications can cause side effects such as:
Yeast may grow when your skin becomes too hot, sweaty and moist. To help prevent this:
Expect symptoms to clear up within a few weeks of starting treatment.
But pityrosporum folliculitis can last for years. Symptoms often go away with treatment and come back when treatment stops. Your healthcare provider might recommend that you continue to use certain creams or medications to prevent symptoms from recurring.
Talk to your healthcare provider if you have “acne” that doesn’t go away with treatment – it may actually be a fungal infection.
