How does anti-dandruff shampoo work?

Dandruff is more than a cosmetic issue. It’s the visible result of accelerated scalp cell turnover, often associated with Malassezia yeast, excess oil and a reactive scalp barrier. That’s why anti-dandruff shampoos live in the treatment aisle: they’re formulated to get symptoms under control.

 

## **The power behind anti-dandruff care**

Anti-dandruff shampoos work in two broad ways: some include antifungal actives; others (like coal tar formulas) are keratoplastic, helping normalize fast turnover, soothe irritation, and break the itch–flake cycle for a calmer-looking scalp.

Coal tar 0.5% stands out as an OTC active that relieves flaking/scaling, itching, irritation and redness by slowing excessive keratinocyte proliferation and supporting scalp comfort.

**Recommendations for use**

**Consistency is key:** work it into your routine 2–3× per week (or as directed) for steady control.

**Gentle massage: **apply to wet hair, massage into the scalp, leave on a few minutes, then rinse thoroughly; repeat if desired.

**Alternate smartly:** on other days, use your favorite cosmetic shampoo/conditioner—keep conditioner mainly on lengths/ends.

Be kind to your scalp: avoid harsh scrubbing and hot tools on irritated skin.

If symptoms persist or worsen, ask a doctor.

By using an anti-dandruff shampoo regularly, you’re not just washing away flakes—you’re targeting the scalp environment so symptoms are easier to manage and hair looks its best.
