The primary cause of dandruff is excess oil production and fungal growth. The scalp has natural oils that can sometimes accumulate, particularly if there is an overproduction. This oil creates an environment conducive to the growth of a common fungus called Malassezia, which thrives on the scalp’s oil and can lead to irritation and flaking. As the skin tries to shed these dead skin cells, it can result in what we recognize as dandruff.

While factors like scalp hygiene, allergic reactions, and stress can influence overall scalp health, they are not the primary drivers of dandruff. Poor hygiene may contribute to the accumulation of dead skin and oil, but it does not directly cause the condition. Similarly, allergic reactions can cause irritation and flaking but are less common causes of dandruff itself. Stress and anxiety can affect overall skin health and exacerbate existing conditions, but they are not considered primary causes of dandruff either. Understanding the role of excess oil and fungal growth is essential for effectively managing and treating dandruff.
