Best Shampoo for Dandruff UK: A Pharmacist's Guide
The best shampoo for dandruff is a medicated anti-dandruff shampoo with an active ingredient suited to your scalp. Ketoconazole is a common first choice for persistent dandruff, while ciclopirox olamine, selenium sulfide, zinc pyrithione and coal tar are alternatives.
Choosing the right shampoo is important, but using it correctly also makes a difference. This guide explains which ingredients to look for, how to use dandruff shampoo and which options are available at Pharmazon Direct.
What is dandruff? Dandruff is the mildest form of seborrhoeic dermatitis of the scalp. It causes itching and white or yellowish flakes and is linked to a yeast called Malassezia, which naturally lives on the scalp. It is not contagious and is not caused by poor hygiene.
What Triggers Dandruff Flare-Ups?
Malassezia lives on most scalps without causing problems. However, flare-ups can happen when the yeast breaks down scalp oils into irritating by-products, causing itching and increased skin shedding.
Common triggers include:
- An oily scalp
- Stress and tiredness
- Cold, dry weather
- Infrequent hair washing
- Product build-up from styling products
Heavy scalp scaling or facial scaling that appears suddenly may sometimes be linked to an underlying condition. Speak to a GP if symptoms develop quickly or become severe.
Which Dandruff Shampoo Suits Your Scalp?
Choose a shampoo based on your scalp condition rather than simply choosing a particular brand.
| Scalp Problem | Active to Look For | Pharmazon Direct Option |
|---|---|---|
| Persistent or recurring dandruff with itch | Ketoconazole | Nizoral Anti-Dandruff Shampoo 60ml |
| Very itchy, flaky or sensitive scalp | Ciclopirox olamine | Oilatum Scalp Anti Dandruff Shampoo 100ml |
| Mild flaking with regular washing | Gentle anti-dandruff shampoo | Vosene Original Anti-Dandruff Shampoo 300ml |
| Dry, itchy scalp between treatments | Gentle soothing shampoo | Aveeno Skin Relief Soothing Shampoo 300ml |
| Thick, stubborn scale | Coal tar or salicylic acid | Ask a pharmacist about stock |
Dandruff Shampoo Ingredients Compared
Different active ingredients work in different ways. Understanding them can help you choose a suitable shampoo.
| Active Ingredient | How It Works | What to Watch For |
|---|---|---|
| Ketoconazole | Antifungal that reduces Malassezia yeast. | Not for children under 12. Follow the pack instructions. |
| Ciclopirox olamine | Antifungal that helps relieve itch and flaking. | Used twice a week according to the Oilatum pack. |
| Selenium sulfide | Antifungal that slows skin cell turnover. | Rinse well, as it can discolour hair. |
| Zinc pyrithione | Has antifungal and antibacterial properties. | Gentle enough for frequent use. |
| Coal tar | Slows skin cell turnover and loosens scale. | Strong smell, may stain light or grey hair and can increase sun sensitivity. |
| Salicylic acid | Loosens and lifts scalp scale. | Can dry the scalp, so use conditioner on the hair lengths. |
Quick answer: What is a medicated shampoo? A medicated shampoo contains an active ingredient that treats a scalp condition, such as an antifungal for dandruff. The active ingredient needs to stay in contact with the scalp for several minutes before rinsing, which is why contact time matters.

Nizoral Anti-Dandruff Shampoo
Our first suggestion for persistent dandruff. Nizoral Anti-Dandruff Shampoo contains ketoconazole, an antifungal that targets the yeast linked to flaking and itch.
Typical use is twice a week for two to four weeks, followed by once every one to two weeks to help prevent dandruff from returning. Check the pack for the exact directions. Do not use it on children under 12, avoid contact with the eyes and stop if irritation develops.
Oilatum Scalp Anti Dandruff Shampoo
Oilatum Scalp Anti Dandruff Shampoo uses ciclopirox olamine and is described as preservative free and gentle on sensitive scalps. It may be an alternative if ketoconazole has not worked or your scalp is easily irritated.
Vosene Original Anti-Dandruff Shampoo
At under £2 for 300ml, Vosene Original Anti-Dandruff Shampoo is a low-cost option for managing mild flaking with regular washes. Read the label for the active ingredient and directions.
Aveeno Skin Relief Soothing Shampoo
If you alternate a medicated shampoo with a gentler wash, Aveeno Skin Relief Soothing Shampoo 300ml is an option for other wash days. It is not a medicated treatment.

How to Use Dandruff Shampoo Properly
Using dandruff shampoo correctly helps the active ingredient work effectively. Follow these simple steps:
- Wet your hair thoroughly and apply the shampoo directly to the scalp, not just the hair.
- Massage gently with your fingertips to build a lather. Avoid scratching.
- Leave it on for the time stated on the pack. Many medicated shampoos need around three to five minutes.
- Rinse thoroughly and repeat if the pack says so.
- Use it at the frequency stated on the label. Switching to your normal shampoo on other days is usually fine.
- Complete the full treatment period, then move to a maintenance wash. Stopping as soon as flakes clear can allow dandruff to return.
Why Is My Dandruff Not Going Away?
When dandruff does not improve, the problem may be short contact time, using too little shampoo or stopping treatment too early. Check these points first.
| Problem | Likely Cause | What to Do |
|---|---|---|
| No change after four weeks | Wrong active ingredient or shampoo rinsed off too quickly | Check contact time, then speak to a pharmacist about switching active ingredients. |
| Flakes return when you stop | No maintenance wash | Use a medicated shampoo once every one to two weeks if directed. |
| Scalp feels dry or tight | Shampoo stripping scalp oils | Apply conditioner to the lengths and reduce frequency as appropriate. |
| Burning, redness or new itch | Irritation or contact allergy | Stop using it and speak to a pharmacist. |
| Flaking only after styling | Product build-up on the scalp | Wash more often and rinse well. |
| Itch with few flakes | Contact dermatitis or another scalp condition | See a pharmacist for assessment. |
Do Tea Tree Oil and Other Home Remedies Work?
Evidence for home remedies is limited. A small trial found that a 5% tea tree oil shampoo improved dandruff, but tea tree oil can cause allergic contact dermatitis in some people.
Apple cider vinegar and lemon juice have no good evidence for treating dandruff and can irritate the scalp. If you want to try a natural product, patch test it first and do not use it as a substitute for an antifungal shampoo if your dandruff is persistent.
Is It Dandruff or Something Else?
Several scalp conditions can look similar but may need different treatment.
- Dry scalp: Small white flakes, often with dry skin elsewhere, and no greasy scale.
- Seborrhoeic dermatitis: Redness and greasy scale, sometimes around the eyebrows or sides of the nose.
- Scalp psoriasis: Thick, silvery plaques with sharp edges that can extend beyond the hairline.
- Fungal scalp infection (tinea capitis): Scaly patches with broken hair, most often in children.
Dandruff shampoos may help with dandruff and some seborrhoeic dermatitis symptoms. Scalp psoriasis and fungal scalp infections need a medical diagnosis.
Using Dandruff Shampoo on Different Hair Types
Treat the scalp rather than the hair lengths. Medicated shampoos can dry the hair, so apply them to the scalp, rinse through the lengths and then condition the mid-lengths and ends.
If you have curly, coily or textured hair, you may not wash as often. Work the shampoo into the scalp in sections and follow the label frequency rather than increasing it.
If your hair is coloured or bleached, ask a pharmacist before using selenium sulfide or coal tar products, as these can affect hair colour.
Safety and Who Should Take Care
- Keep medicated shampoo out of your eyes and rinse well if it gets in.
- Do not use ketoconazole shampoo on children under 12.
- If you are pregnant or breastfeeding, ask a pharmacist before starting a medicated or coal tar shampoo.
- Coal tar shampoos can stain light or grey hair and increase sun sensitivity. Protect your scalp outdoors.
- If you already use a topical steroid on your scalp, ask a pharmacist how to combine the treatments.

Final Thoughts
Choosing the right dandruff shampoo depends on your scalp and the type of flaking you experience. Ketoconazole is a common starting point for persistent dandruff, while other active ingredients may suit different scalp needs.
Use your shampoo as directed, allow enough contact time and complete the recommended treatment period. If symptoms do not improve after four weeks, or your scalp becomes sore or inflamed, speak to a pharmacist or GP.
