This balanced approach prevents worsening either condition.

FAQ

1. What is the main difference between dandruff and dry scalp?

Dandruff is caused by excess oil and fungal overgrowth on the scalp, while dry scalp occurs due to lack of moisture. Although both cause flaking, they require very different treatments.

 

2. How can I tell if my flakes are dandruff or dry scalp?

  • Dandruff flakes are large, oily, and yellowish-white

  • Dry scalp flakes are small, dry, and white

If flakes stick to hair and scalp, it’s likely dandruff. If they fall easily, it’s usually dry scalp.

 

3. Does dandruff mean my scalp is dry?

No. Dandruff usually occurs on an oily scalp, not a dry one. Adding heavy oils can worsen dandruff by feeding the fungus that causes it.

 

4. Which condition causes more itching?

Dandruff typically causes moderate to severe itching due to inflammation.
Dry scalp itching is usually milder and related to dehydration or irritation.

 

5. What products work best for dandruff?

Dandruff responds best to antifungal shampoos containing:

  • Zinc pyrithione

  • Ketoconazole

  • Selenium sulfide
