What Does Each One Mean?

Let’s start by understanding what dandruff and dry scalp actually mean.

What Is Dandruff?

Dandruff is a scalp condition caused by too much oil (sebum) and the overgrowth of a fungus called Malassezia.
It leads to greasy flakes that are often yellowish or white, and an itchy scalp.

Part of speech: Noun
Meaning: Flaky skin caused by excess oil and yeast on the scalp.

Examples:

1. I used an anti-dandruff shampoo to get rid of flakes.
2. Dandruff often gets worse in winter.
3. He scratched his head because dandruff made it itchy.

🧠 Mini Tip: Think of dandruff as an oily problem — too much oil causes irritation and flakes.

What Is Dry Scalp?

Dry scalp happens when your scalp doesn’t have enough moisture.
It’s similar to having dry skin on your hands or face — your scalp becomes tight, itchy, and sheds small, dry flakes.

Part of speech: Noun phrase
Meaning: Flaking and itching caused by lack of moisture on the scalp.

Examples:

1. My dry scalp feels tight after washing my hair.
2. Using a gentle shampoo can help relieve dry scalp.
3. A dry scalp often comes from cold weather or harsh hair products.

🧠 Mini Tip: Think of dry scalp as a dry skin issue — not enough oil or moisture.
