A common cause of dandruff is indeed dry scalp or fungal growth. Dandruff often manifests as white or yellow flakes on the scalp and hair, which can be attributed to a condition known as seborrheic dermatitis, where the scalp becomes oily and irritated, leading to flaking. Additionally, the presence of a fungus called Malassezia is frequently linked to dandruff; this fungus thrives on the natural oils of the scalp and can disrupt the natural skin renewal cycle, contributing to the shedding of skin cells.

Recognizing dry scalp and fungal growth as key contributors helps in understanding the underlying issues that may need to be addressed in treatment options, such as using antifungal shampoos or moisturizing products designed to alleviate dryness. While factors like overuse of hair gel, exposure to cold weather, and excessive washing can impact scalp health, they are secondary causes compared to the direct effects of dryness and fungal overgrowth that primarily lead to dandruff formation.
