What is the role of the Malassezia fungus when it becomes overactive?

When the Malassezia fungus becomes overactive, it plays a significant role in leading to dandruff. This fungus is a type of yeast that naturally inhabits the scalp and is typically harmless. However, when it grows excessively, it can disrupt the balance of the scalp’s microbiome and can contribute to inflammation. This inflammation can cause the skin cells on the scalp to turn over more quickly, leading to the shedding of dead skin cells in the form of flakes commonly associated with dandruff.

The presence of Malassezia is particularly linked to seborrheic dermatitis, a more serious condition that includes dandruff as a symptom. It is characterized by an oily scalp, redness, and more significant flaking. Understanding this relationship is important for addressing scalp health, as effective treatments often focus on reducing the population of this fungus or its effects on the scalp.

In this context, the other options do not accurately reflect the consequences of Malassezia overgrowth. Strengthening hair and promoting hair growth are not associated with its overactivity.
