Malassezia Furfur is a yeast known to grow in the hair follicles and on the skin. It is not known to be contagious. Much like most yeast and fungi, their main food supply is an excess circulation of sugars and refined carbohydrates in the body; however, Malassezia Furfur is also known to feed off the fats and oils found on the skin and hair follicles. Therefore, if you have greasy skin or scalp, this may contribute to overgrowth. Some yeast and fungi are needed and required by the body to help break down foods, although an overgrowth can lead to different symptoms and issues. It is recommended to limit the amount of refined and processed sugars and carbohydrates initially to begin the process of rebalancing the yeast overgrowth and reduce inflammation in the body to rebalance the number of oils found on the skin and scalp.
