Dandruff is caused by which of the following?

• A. Genetics, illness, medications, hormones, or stress
• B. Excessive oiliness of the scalp
• C. Excessive shedding of dead skin cells caused by a fungus
• D. Beaded hair caused by irregular growth

Answer: (C)

Dandruff stems from an overgrowth of a fungus on the scalp, which speeds up the shedding of dead skin cells. The common culprit is Malassezia, a yeast that feeds on scalp oils and irritates the skin, triggering faster skin turnover and resulting in the visible flakes. So the process is about excessive shedding of dead skin cells caused by a fungus. Genetics, illness, medications, hormones, or stress can influence how severe it is, but they’re not the direct cause. An oily scalp can help the fungus thrive, but it isn’t the fundamental mechanism. Beaded hair from irregular growth is unrelated to dandruff.
