What Is Dandruff?
Dandruff is the visible shedding of keratinized scalp cells. Normally, these cells fall off as tiny, invisible flakes. When the scalp’s metabolism becomes imbalanced, keratin accumulates and sheds in large white clusters, resulting in dandruff.
The Role of Malassezia in Dandruff
Malassezia is a natural yeast fungus on the scalp.
Excess oil or a weakened scalp barrier allows it to multiply excessively.
Enzymes break down sebum into fatty acids, irritating the scalp.
This leads to inflammation, abnormal skin cell growth, and visible flakes.
The Three Major Triggers of Dandruff
1.Overgrowth of Malassezia
2.Excessive scalp sebum production
3.Individual sensitivity or genetic predisposition
When these three factors overlap, dandruff tends to persist and recur.
