Most dandruff is caused by *Malassezia*, a yeast that feeds on scalp oil. This is why the common advice — oil the scalp more — often makes flaking worse, not better.
1. Use an active shampoo, not a "smooth hair" one
Look for ketoconazole, zinc pyrithione, selenium sulfide or salicylic acid on the label.
2. Leave it on for 3–5 minutes
An anti-dandruff shampoo rinsed immediately does almost nothing. The active needs contact time.
3. Use it 2–3 times a week, not daily
Then alternate with a gentle shampoo on other days.
4. Stop oiling while flaking is active
Oil feeds the yeast. Resume once the scalp is settled.
5. Rotate actives if it stops working
Malassezia adapts. Switching between two actives keeps results steady.
When to see a doctor
Bleeding, thick yellow crusts, severe itch or hair loss with patches is not ordinary dandruff. See a dermatologist.
