Dandruff is the product of the metabolism of human head epidermal cells. The physiological process of the head epidermis is called keratinization. The epidermis forms cells from the basal layer, proliferates and divides, and gradually moves to the upper layer.

The dry dead cells fall off automatically in the form of scales or flakes, which is commonly known as dandruff.
