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.
