Dandruff itself is not a fungus, though its cause is the presence of a natural fungus, Malassezia globosa that breaks down the oil on your scalp, called sebum. This process produces oleic acid, and one in two people worldwide are sensitive to this acid.
If you're sensitive to this acid, your scalp becomes irritated and increases the speed at which skin cells renew in their attempt to get rid of what's irritating them. This causes skin cells to build up and form the flakes we know as dandruff.
To get rid of dandruff, anti-dandruff shampoos prevent the irritants that cause it from forming.
