What is dandruff?
Dandruff is simply flakes of dead skin that form on the scalp. The official medical term for dandruff is “Pityriasis
capitis,” and is often accompanied by itching, redness, and irritation. It’s normal for skin cells to die and
flake off, so a small amount of flaking is normal and quite common, but some people experience an unusually large
amount of flaking and need to take steps to reduce the problem.
