Question: 1 / 400

What is the main cause of dandruff?

Dry scalp

Allergies to hair products

A yeast-like fungus called Malassezia

The main cause of dandruff is a yeast-like fungus known as Malassezia. This fungus is naturally present on the scalp, but for some individuals, it can proliferate excessively, leading to irritation and an increase in skin cell turnover. As dead skin cells accumulate and shed, they can become visible as flakes of dandruff.

While dry scalp can contribute to the appearance of dandruff, and allergies to hair products or infrequent washing may exacerbate symptoms, they are not the primary cause. Understanding the role of Malassezia is crucial for addressing dandruff effectively, as antifungal treatments may be necessary to reduce its levels on the scalp and alleviate symptoms.
