How to Get Rid of Dandruff: Treatment, Scalp Care and What to Do If It Keeps Coming Back

Quick answer

Managing dandruff usually means choosing a treatment suited to the scalp problem, using it according to its instructions and supporting it with a comfortable, gentle scalp-care routine.

Anti-dandruff and medicated shampoos contain different ingredients with different purposes. Some target yeast associated with dandruff, while others help manage scaling, flaking or itching.

Symptoms can improve and later return, so getting rid of visible flakes is not the same as a guaranteed permanent cure. If treatment is not helping, review what you are using, how you are using it and whether dandruff is the right explanation for the symptoms.

Your next steps at a glance

Understand what you are treating. Check the whole symptom pattern, because flakes alone cannot confirm dandruff.
Choose an appropriate treatment. Check its purpose and suitability, then follow its own application, frequency and duration instructions.
Support it with scalp care. Cleanse gently, avoid forceful flake removal and keep product changes manageable.
Review symptoms that persist or return. Use the troubleshooting checklist below to check treatment use, irritation and changes that may need reassessment.

Why is it sometimes difficult to get rid of dandruff?

When flakes keep appearing on your clothes or your scalp will not stop itching, it is understandable to want a quick answer. You may already have tried several shampoos and be wondering what to change next.

Part of the difficulty is that “dandruff shampoo” does not describe one interchangeable treatment. Another is that not every flaky scalp has the same underlying problem.

The aim is to make your next step clearer, rather than add more products to an already confusing routine.

Stage 1: Understand what you are treating

Check the overall symptom pattern

Dandruff typically causes visible white or yellow flakes, sometimes with mild itching and relatively little inflammation. It is associated with an inflammatory response involving Malassezia, a yeast that naturally lives on human skin.

That brief explanation matters because dandruff is more than loose skin that needs washing away. Cleansing can remove flakes, but treatment may also need to address factors contributing to continued flaking.

For the fuller condition overview, see What Is Dandruff? Causes, Symptoms and How to Manage It.

Before choosing a product, notice whether the main concern is familiar mild flaking, a dry or tight feeling, significant discomfort, or a change from previous episodes. These observations help describe the problem. They cannot confirm a diagnosis on their own.

Leave room for other explanations

Dry scalp, seborrhoeic dermatitis, psoriasis and eczema can also cause flakes. Product irritation may contribute to dryness or discomfort.

A dry-feeling scalp does not automatically mean that adding moisture will resolve the problem. Equally, a new product causing irritation does not necessarily mean that dandruff has become more severe.

If dryness seems central to your symptoms, What Causes Dry Scalp? Understanding Dryness, Flakes and Underlying Scalp Conditions explains that distinction.

Marked soreness, noticeable inflammation, thick scale or clearly defined plaques deserve assessment rather than being treated as ordinary dandruff by default.

Stage 2: Choose an appropriate management approach

Understand what the shampoo is intended to do

Ordinary cosmetic shampoos primarily cleanse the hair and scalp. This may remove loose flakes and make them less noticeable temporarily.

Anti-dandruff or medicated shampoos contain ingredients intended to address particular aspects of dandruff or related scalp conditions. Looking at the active ingredient and the product's stated purpose is more useful than choosing on the name alone.

Recognised option	Main purpose	What to understand
Ketoconazole shampoo	Targets fungi and yeasts, including Malassezia	Commonly used in dandruff and seborrhoeic dermatitis management
Coal tar shampoo	Helps manage scaling, flaking and associated itching	One recognised option for certain scaling scalp conditions
Products containing salicylic acid	May help soften and loosen built-up scale	Scale removal is a different purpose from targeting yeast
Products containing piroctone olamine	Included in some anti-dandruff formulations	Check the individual product's stated purpose and directions

This is a guide to different purposes, rather than a ranking or a suggestion to combine ingredients.

For example, targeting yeast and loosening scale are different jobs. Products that both say “anti-dandruff” on the label may therefore have different roles and instructions.

Where does Polytar fit?

Polytar is a licensed medicated scalp shampoo containing coal tar solution 4% w/w. Its approved uses include dandruff and other specified scalp conditions.

Coal tar shampoos may help manage flaking and associated itching. Polytar is one recognised option within wider treatment pathways, rather than the appropriate choice for every flaky scalp or a way to prevent symptoms permanently.

Suitability depends on the underlying problem, the individual product information and your circumstances.

Check the instructions before changing your routine

For the product you are considering or already using, check:

What conditions or symptoms it is intended for.
Whether the label or leaflet identifies any suitability restrictions.
How it should be applied.
Whether a contact time is specified.
How frequently and for how long it should be used.
What precautions or advice about irritation apply.

Do not transfer the directions from a previous shampoo to a new one. Nor should you increase frequency or contact time simply because you want faster results.

If something is unclear, a pharmacist can explain the product directions. That is a focused question about use, rather than a requirement to seek advice before every routine decision.

Stage 3: Support treatment through scalp care

Choose a washing routine that keeps your scalp comfortable

There is no universally correct washing frequency for dandruff. Daily washing is not automatically necessary, and washing less is not automatically better.

Regular cleansing can remove loose flakes, excess oil and product residue. However, very frequent washing or products that remove too much natural oil may contribute to dryness or irritation in some people.

Those effects should be distinguished from the underlying dandruff itself.

Notice how your scalp feels after washing. Increasing tightness or irritation is relevant information, especially if it began after a product or routine change. Your ordinary washing routine should also fit with the instructions for any medicated treatment.

Avoid forceful flake removal

It is tempting to scratch or scrub until all the flakes have gone. Aggressive rubbing and scratching can make an uncomfortable scalp feel more irritated.

Removing loose flakes through gentle cleansing is different from picking or forcing off attached scale. Thick or persistent scale may need an appropriate management approach, rather than more pressure.

A scalp that looks temporarily clearer after scrubbing has not necessarily had the underlying problem addressed.

Make product changes easier to evaluate

If you change several shampoos, styling products and scalp treatments together, it becomes difficult to understand what helped or what coincided with irritation.

Where possible, keep changes clear and manageable. Note the product, when you started using it, how you used it and what happened to the symptoms.

This does not mean you must continue a product that causes discomfort. Burning, stinging or increasing irritation should be taken seriously and considered alongside the product's precautions.

Repeatedly swapping products without a clear reason can make your routine harder to assess.

Keep scalp care separate from treatment claims

A comfortable routine supports care of the scalp, but it should not be presented as a substitute for appropriate treatment.

Similarly, moisturising genuinely dry skin and treating dandruff are not necessarily the same task. Home remedies and general lifestyle tips should not be assumed to do the job of recognised dandruff treatments.

Stage 4: Respond to persistent or returning symptoms

What if I have tried dandruff shampoo and it is not working?

Before buying another product, check its purpose, how you used it and how your scalp responded. Use the table to work out whether you need to clarify the instructions, discuss irritation or have the symptom pattern reassessed.

Check	Practical question	Why it matters
Product purpose	Was it a cleansing shampoo or a product intended to treat dandruff?	Washing away flakes and treating the condition are different
Active ingredient	What was the ingredient intended to address?	Different ingredients have different roles
Application	Did you follow the specified method and any contact time?	An appropriate product still needs appropriate use
Frequency and duration	Did your use match the individual instructions?	There is no single schedule for every medicated shampoo
Tolerance	Did the scalp become drier, sore or irritated?	Added discomfort may need a separate explanation
Symptom pattern	Are the symptoms familiar, or is there thick scale, inflammation or a new distribution?	Another condition may need consideration

These checks help you describe the situation and identify a clear next step. They do not prove that the product is ineffective or that you need a stronger treatment.

If you realise that your use differed from the directions, check how to proceed using the leaflet or professional advice. Do not compensate by using more product, increasing contact time or combining treatments independently.

If you followed the directions and symptoms remain persistent, treatment reassessment may be more useful than another unplanned switch.

How quickly should dandruff improve?

There is no single timeframe that can be applied to every shampoo or every scalp.

Some medicated treatments require consistent use before benefits become apparent, but the relevant frequency, duration and expectations depend on the individual product. Follow its instructions rather than judging all products after the same number of washes.

You can note changes in visible flaking, itching and scalp comfort without expecting all symptoms to change at once. If symptoms become more uncomfortable, that deserves attention rather than simply waiting longer.

The aim is to judge an appropriately used treatment, without promising an overnight result or inventing a universal trial period.

What if it improves, then comes back?

Dandruff can follow a recurring pattern. Flakes and itching may improve for a period and return later, without that automatically meaning treatment failed.

Factors associated with dandruff, including Malassezia and the individual's response, may continue to influence the scalp.

For familiar returning symptoms, review the product's directions about repeat or ongoing use. Some people may need maintenance management, but there is no schedule that should be applied to everyone.

Do not assume that every medicated shampoo should be used indefinitely or stopped as soon as the last visible flake disappears. The appropriate approach depends on the product information and, where needed, professional advice.

When should the problem be reassessed?

Seek advice when symptoms persist despite appropriate use, become difficult to manage or change noticeably.

Particular reasons include significant redness or soreness, troublesome itching, thick scale, clearly defined plaques or symptoms extending beyond the scalp.

Bring the product name or leaflet and explain how you used it. Include what improved, what did not, and whether any new discomfort appeared.

A pharmacist can help with treatment suitability and use. A GP or dermatologist can assess persistent, severe or unclear symptoms and whether another scalp condition is contributing.

Frequently asked questions

How can I get rid of dandruff fast?

Gentle cleansing may remove loose flakes, but that is different from treating the underlying problem. There is no guaranteed rapid result for every scalp. Follow the chosen treatment's directions; using it more often or leaving it on longer is not a shortcut to faster relief.

How can I get rid of dandruff permanently?

No treatment can be presented as a guaranteed permanent solution. Symptoms may improve and return later. If they recur, check the product's directions for repeat or ongoing use rather than assuming you need a stronger shampoo.

What if dandruff shampoo isn't working?

Start with the Stage 4 troubleshooting table: check the product's purpose, application, frequency, duration and any new irritation. If you have used it as directed and symptoms persist, take the product details and a record of your response to a pharmacist or GP for reassessment.

Should I rotate or combine dandruff shampoos?

Different ingredients are not a ready-made combination plan. Use individual product directions or advice specific to your situation rather than creating your own rotation or combined-treatment schedule.

What should I do if the shampoo irritates my scalp?

Follow the product's precautions and advice about irritation. Note when discomfort appeared and seek advice if it persists or worsens. Irritation should not be taken as a sign that treatment is working.
