Dry scalp and dandruff are related but not the same.

Dry scalp refers to a lack of moisture in the skin on your scalp, which can cause itchiness and flaking.

Dandruff, on the other hand, is often caused by an overgrowth of yeast on the scalp, leading to excessive flaking and sometimes inflammation.

While both can result in flaking, dandruff typically involves larger, oilier flakes and may require specific treatments.
