Is It Dandruff or a Dry Scalp?

Quick answer: Dandruff usually shows as larger, oily, yellowish or white flakes with itch, linked to yeast on an oily scalp, while dry scalp gives small, fine white flakes and tightness; anti-dandruff shampoos help the first, gentler moisturising care helps the second.
- Dandruff: Common in humid climates.
- Dry scalp: Often after harsh shampoos or air-conditioning.
