Top Anti-Dandruff Shampoos to Consider
1. Ketoconazole Medicated Anti-Dandruff Shampoo

2. Zinc Pyrithione Daily Anti-Dandruff Shampoo

Buying Guide
- Identify the cause: True dandruff (seborrhoeic dermatitis) is fungal and responds to medicated shampoos; dry scalp flaking from dehydration needs a moisturising approach, not anti-fungals.
- Rotate shampoos: Using one anti-dandruff shampoo exclusively for months can lead to reduced efficacy as the fungus adapts; alternating between ketoconazole and zinc pyrithione maintains effectiveness.
- Leave-in time: Apply and leave the shampoo on for 3–5 minutes before rinsing to allow active ingredients to work. Simply lathering and rinsing immediately wastes the formula.
- Avoid hot water: Hot water inflames the scalp and can worsen dandruff; use lukewarm water when washing hair to avoid stripping protective oils.
- Conditioner use: Apply conditioner from mid-length to tips only — avoiding the scalp prevents product build-up that can feed Malassezia and worsen dandruff.
Frequently Asked Questions
Is dandruff contagious?
No — dandruff is not contagious. It is caused by an overgrowth of Malassezia fungi that naturally lives on everyone’s scalp, triggered by factors like oily skin, stress, or sensitivity to certain hair products.
Why does dandruff worsen in winter in India?
In winter, lower humidity dries out the scalp while people also wash hair less frequently, allowing oil and skin cells to accumulate. Fungal growth is also affected by scalp temperature changes during the season shift.
How long does it take an anti-dandruff shampoo to work?
Most medicated shampoos show visible improvement within 2–4 weeks of regular use. Ketoconazole-based formulas often produce results faster, sometimes within 1–2 weeks of twice-weekly applications.
