Pityrosporum folliculitis is caused by a yeast species known as Malassezia furfur. These species thrive in sebaceous environment since they convert triglycerides into free fatty acids and feed on them as a result cause inflammation in those areas.
Malassezia is found on the skin of health people. They are present on the skin immediately after birth and become many in late adolescence and early in adulthood.
Particular climate plays a key role in influencing the number of people with Pityrosporum folliculitis. People living in humid and warm environment are largely affected by pityrosporum folliculitis.
Pityrosporum folliculitis affects young and middle-aged adults and youths. This condition is common in people who are 15-45 years of age. Both male and female are affected.
Malassezia folliculitis causes are not yet understood. However there are factors that are believed to promote growth of yeast on the skin of people. They include the following:1, 2, 5
Use of certain medications can promote pityrosporum folliculitis. Drugs such as oral antibiotics are used to kill skin bacteria but not yeast. This allows yeast to reproduce and attack your skin causing pityrosporum folliculitis. For example long term use of tetracyclines can encourage the growth of malassezia.
Another medication is oral contraceptive which is a birth control drug that is used to prevent pregnancy. These medications has estrogen and progestin component. Although oral contraceptives are used in preventing pregnancy, they can also treat skin disorders. However oral contraceptives can cause other skin conditions including pityrosporum folliculitis.

People who are overweight tend to sweat more. The sweat provides a favorable environment for this yeast to thrive and reproduce.
This is where the ability of your body to defend against infection is greatly reduced and therefore makes you more prone to bacterial, viral and fungal infections. Immunodeficiency conditions are either acquired or inherited. Acquired immunodeficiency you obtain them as you live while inherited immunodeficiency is that which is passed to you at birth.
Therefore those people with a weak immune system are at greater risk of developing pityrosporum folliculitis.
This refers to a group of yeast infections that affect your brain, heart and any other part of your body. It is mostly caused by Candida yeast. This yeast lives on the skin and in your digestive system and usually do not cause any problem.

The cells need insulin, a hormone that enables the cells to absorb glucose and use it for energy. However, with diabetes mellitus, your body is either not able to make adequate insulin or use it.
Since your body cells cannot absorb glucose, it accumulates in your blood. These increased levels of glucose in your blood can damage your blood vessels in your heart, kidney, eyes and nervous system.

Other external factors that can promote pityrosporum folliculitis include:
- Applying coconut oil and greasy sunscreens on the skin provides oil that this yeast feeds on and reproduces.
