Yeast: Dandruff is seborrhiec dermatitis in the scalp. This is due to an overgrowth of yeast named pityrosporum ovale. Some make sebum (oils) especially preferential for them to grow. If your immune system reacts to it, your skin becomes inflamed red and flaky, thus the dandruff. Start by using head and shoulder, nizoral, (ketoconazole) neutrogena tgel or tsal shampoo, lather and leave in for 5-10min before rinsing.

Depends: Dandruff is flaking of the scalp. It can be simple shedding of skin. Can be due to sun burn. Can be due to infection, inflammation or other acute causes. Mostly, however, it is due to seborrheic dermatitis. This is an inflammation of the skin often due to a low grade fungal infection or a reaction to oils in the scalp. Best treated with tar shampoos or antifungal shampoos. Maybe topicals.
