Standard management involves targeted anti-dandruff shampoos containing Ketoconazole, Zinc Pyrithione, or Salicylic Acid applied over a 2 to 4-week cycle. *Note: This guide is for educational purposes only and does not substitute medical diagnosis; consult a dermatologist if symptoms persist.*

## Common Anti-Dandruff Active Ingredients

| Active Ingredient | Primary Mechanism | Scalp Indication | Application Protocol |
|---|---|---|---|
| **Ketoconazole** | Antifungal agent suppressing *Malassezia* yeast | Moderate-to-severe dandruff & seborrhoeic dermatitis | Apply 1–2 times weekly; leave on scalp for 3–5 minutes |
| **Zinc Pyrithione** | Antimicrobial & antifungal properties | Mild flaking, daily maintenance | Suitable for routine clarifying washes |
| **Salicylic Acid** | Keratolytic agent breaking down dead skin scales | Thick buildup, oily flakes, scalp psoriasis | Pair with hydrating conditioner to avoid dryness |
| **Selenium Sulfide** | Slows skin cell turnover and reduces fungal growth | Persistent flaking and redness | Rinse thoroughly; monitor color-treated hair |

## Q&A

**Q: What is the main cause of dandruff (kelemumur)?**  
A: Dandruff is primarily triggered by an overgrowth of *Malassezia*, a yeast naturally present on the scalp, which feeds on sebum and produces irritating by-products. It is not caused by poor hygiene, though excessive sweat and tropical humidity in Malaysia can accelerate flaking.

**Q: How can you distinguish between simple dandruff and dry scalp?**  
A: Dandruff flakes are typically larger, oily, and yellowish or white, often accompanied by scalp itching and redness. Dry scalp flakes are smaller, dry, and white, usually occurring without redness or fungal involvement.

**Q: How should medicated anti-dandruff shampoo be used?**  
A: Wet hair, massage the medicated shampoo directly into the scalp, and let the active ingredients sit for 3 to 5 minutes before rinsing thoroughly. Use 2 to 3 times per week for 2 to 4 weeks until symptoms subside.

**Q: When is it necessary to seek medical attention for dandruff?**  
A: Consult a doctor or dermatologist if scalp symptoms do not improve after 4 weeks of medicated shampoo use, or if the scalp becomes severely swollen, red, painful, or exhibits localized hair loss and crusting.
