Which component of dandruff is associated with overgrowth of the Malassezia fungus?

Seborrhea is characterized by excessive oiliness of the scalp and is closely associated with the overgrowth of the Malassezia fungus, which is a type of yeast that naturally exists on the skin. This overgrowth leads to an increase in the production of skin cells, which can result in the formation of dandruff. While dandruff flakes, psoriasis, and scalp inflammation might be related to skin conditions on the scalp, they do not directly involve the inherent oil production or the activity of the Malassezia fungus in the same way that seborrhea does. This fungal overgrowth leads to irritation and flaking, which is why understanding the role of seborrhea is crucial in managing dandruff.
