How to Get Rid of Dandruff in 2–4 Weeks


Overall Objective

This guide lays out a 4-week routine to control an active dandruff flare in the first 2 weeks and consolidate results in the next 2. Alternate ketoconazole, selenium, zinc, and add salicylic acid only if thick plaques persist. Apply to the scalp, keep 3–5 minutes of contact, and use a double lather during the active flare.


Weeks 1–2 (active flare) — 6–7 washes per week

- Monday: Ketoconazole
- Tuesday: Selenium
- Wednesday: Zinc
- Thursday: Ketoconazole
- Friday: Selenium
- Saturday: Zinc or Salicylic acid (if thick plaques)
- Sunday: Gentle shampoo or rest (if the scalp is calm)
Usage instructions (for each indicated day):
Apply shampoo directly to the scalp, leave 3–5 minutes before rinsing, and do a double lather if there’s heavy oil or flaking. Rinse with lukewarm water.


Weeks 3–4 (consolidation) — 4–5 washes per week

- Monday: Ketoconazole
- Tuesday: Rest
- Wednesday: Selenium
- Thursday: Rest
- Friday: Zinc
- Saturday: Salicylic acid (if flaking continues; otherwise Zinc)
- Sunday: Ketoconazole
Objective:
Reduce wash frequency while maintaining the control achieved during the flare phase.


Quick Rules (apply throughout the routine)

- Shampoo goes on the scalp (no need on hair lengths).
- 3–5 minutes contact and double lather during flare weeks.
- Use lukewarm water, not hot.
- Gentle brushing before shower to loosen flakes (no scratching).
- If a product irritates, swap that active for another from the list that week.
- Brows/beard: you can use the same anti-dandruff shampoo 2–3 minutes, then rinse.


Signs of Progress (what to expect)

With consistency, you should notice fewer “snow-like” flakes, less itch, and less redness within 2–3 weeks.
