Dandruff is the excessive flaking of dead skin that forms on the scalp.
As it is normal for skin cells to die and flake off, a small amount of flaking is normal and in fact quite common.
Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can be not only a visual nuisance, but is also often accompanied by redness and irritation.
