The Seb Derm Directory: Scalp and Hair Products That Actually Help (UK Edition)

There’s a specific kind of despair that comes from standing in Boots, holding a shampoo that promises to fix your flaky scalp, flipping it over to read the ingredients, and having absolutely no idea what you’re looking at. Is this going to help? Is it going to make everything worse? Is that fatty acid in position four a problem? Who knows. Not me. Not then, anyway.

I’ve spent years figuring out what works for seborrhoeic dermatitis on my scalp. A lot of money. A lot of avoidable flares. Mostly because nobody just handed me a list. So. Here’s the list.

This is a directory, not a review post. Everything here is something I consider worth trying, rotating, or at least knowing about if you’re dealing with seb derm. All of it is available in the UK. Products are split by category so you can go straight to what you need without reading anything you don’t.

If you’re overwhelmed, start here: one antifungal shampoo, one gentle maintenance shampoo, one leave-on scalp treatment. That’s it. Don’t rebuild your entire routine overnight. The rest of the list will still be here when you’re ready for it.

Before you start shopping: bookmark Sezia. It’s free. You paste in an ingredient list and it flags ingredients commonly associated with feeding Malassezia. It has saved me from a lot of expensive mistakes. Use it for everything, including things on this list – because skin is personal and what works for me might not be right for yours. Formulas change too, so always run the current UK INCI before you buy.

Quick disclaimer: I’m not a dermatologist. I’m just someone who’s been managing this for a long time and wants to save you some of the trial and error. If things are severe or nothing is shifting, please see a doctor.

Last updated: July 2026. Formulas change – always check the current INCI through Sezia before buying.

Still figuring out whether what you have is scalp seb derm, facial seb derm, or both? I covered the differences in this post on scalp vs face seb derm. And if it’s face products you’re after, the Seb Derm Face Skincare Directory is the companion to this one.

Antifungal Shampoos

These are the ones doing the heavy lifting. The goal with a seb derm shampoo is either to directly target Malassezia yeast with antifungal ingredients, or to keep the scalp environment clean and calm without feeding the problem. Most people end up rotating two or three of these rather than using one exclusively.

Ketoconazole shampoos

Nizoral 2% Ketoconazole Shampoo

The gold standard. Ketoconazole is an antifungal that directly targets Malassezia at the source. Use two or three times a week during flares, leave it on for three to five minutes before rinsing – the contact time is not optional, it’s what makes it work. Once things are calm, drop to once a week for maintenance. If you only buy one thing off this entire list, make it this. Available at Boots, Superdrug, and most pharmacies.

Sons Ketoconazole Anti-Dandruff Treatment Shampoo

A milder-feeling ketoconazole option for anyone who finds Nizoral a bit stripping on the hair shaft. Same active ingredient, gentler base formula. Good for rotation or for people with drier or more fragile hair alongside seb derm.

Rohto Mentholatum Mediquick H Scalp Shampoo

A Japanese quasi-drug shampoo available via Stylevana that uses miconazole nitrate as its antifungal active – so it’s genuinely targeting Malassezia, not just cosmetically promising it. Dipotassium glycyrrhizinate adds anti-inflammatory backup. Silicone-free, mildly acidic formula. Worth running the full INCI through Sezia before committing, but the active itself is solid and the formula is different enough from ketoconazole to make it a useful rotation option.

Piroctone olamine and climbazole shampoos

Bioderma Nodus DS+ Seborrhoeic Dermatitis Shampoo

Uses climbazole, salicylic acid, and zinc pyrithione together – three different mechanisms in one formula. Worth rotating with a ketoconazole shampoo. Check current UK availability as EU regulations in 2022 affected zinc pyrithione formulas.

Philip Kingsley Flaky Itchy Scalp Shampoo

Piroctone olamine-based, much kinder to the hair shaft than ketoconazole shampoos. Good as a between-washes maintenance option when you’re rotating with something stronger. Fragrance-light, suitable for reactive scalps.

Vosene Original Anti-Dandruff Medicated Shampoo

Zinc-based, widely available, cheap. One of the most accessible options on this list. Check current UK listing for zinc pyrithione status before buying.

Head & Shoulders Bare Pure Clean Anti-Dandruff Shampoo

The stripped-back version of a shampoo you’ve probably had in your shower at some point without ever checking what’s in it (I know I hadn’t). Bare is Head & Shoulders’ minimal-ingredient anti-dandruff line – sulfate-free, no silicones, no dyes, and it’s genuinely made for oil-prone scalps rather than a one-size-fits-all formula. Gentle enough for daily use, which matters if you’re someone who can’t face rotating three different shampoos on a Tuesday morning (me, most weeks). Not going to replace ketoconazole during an active flare, but a solid everyday option for keeping an oily, dandruff-prone scalp in check between the heavier hitters.

Sulfur shampoos

Sulfur is an old-school antifungal and antibacterial that’s been used for skin conditions for decades, and it genuinely works for seb derm. The downsides are real: it smells like eggs, it can be drying on the hair shaft, and it’s not for the faint-hearted. But if ketoconazole isn’t cutting it on its own, adding sulfur into the rotation is genuinely worth trying – especially for stubborn or treatment-resistant cases.

Jason Dandruff Relief 2-in-1 Shampoo and Conditioner

2% sulfur and 1% salicylic acid. The most widely available sulfur shampoo in the UK. Not as high-concentration as some options but genuinely effective, especially as part of a rotation. Available on Amazon UK.

Sulfur8 Anti-Dandruff Hair and Scalp Conditioner

Higher concentration sulfur treatment, more targeted. Use it on specific patches rather than all over. Available on Amazon UK. Strong smell – forewarned is forearmed.

Coal tar shampoos

For the thick, greasy, crusty variety of seb derm. They have a distinctive smell, can be drying on the hair itself, and may temporarily affect colour-treated hair. Use during flares rather than as ongoing maintenance – they’re heavy hitters, not everyday shampoos.

Polytar Scalp Shampoo

Specifically marketed for seb derm, dandruff, itching, and scaling. The one I’d reach for first in a bad crusty flare.

Capasal Therapeutic Shampoo

Salicylic acid, coconut oil, and tar combined. Good for thick, built-up, difficult-to-shift seb derm. The coconut oil in the formula is worth noting if you’re very Malassezia-reactive – it’s a rinse-off product so contact time is limited, but worth knowing.

Neutrogena T/Gel Scalp Relief Shampoo

Gentler than Polytar and Capasal, more focused on soothing itch and inflammation rather than clearing thick buildup. A better entry point if your coal tar experience is new.

Malassezia-conscious non-medicated hair care

I ran a lot of ingredient lists through Sezia to find these. Treat everything here as “appeared Malassezia-friendly when I last checked” – formulas change, always verify with the current UK INCI before buying.

Sebamed Anti-Dandruff Shampoo

Scalp-friendly pH, gentle formula. Good for days between medicated washes when your scalp needs something clean but not stripping.

K18 PEPTIDE PREP Detox Shampoo

Salicylic acid, no problematic esters in the version I screened. Good for product buildup and congestion between antifungal washes.

Vanicream Free and Clear Shampoo

Fragrance-free, minimal ingredient list. For very angry, reactive scalps that can’t tolerate anything with any extras in it. Not glamorous. Gets the job done without making things worse, which during a bad flare is genuinely all you need.

Olaplex No.4C Bond Maintenance Clarifying Shampoo

Clarifying formula, removes buildup without a problematic ester base. Good for scalp hygiene maintenance between medicated washes.

Olaplex No.4 Bond Maintenance Shampoo

The everyday version. Screens well. Good if you’re using Olaplex across your routine and want the whole system to be as consistent as possible.

L’Oreal Professionnel Scalp Advanced Anti-Discomfort Shampoo

Formulated for sensitive, reactive scalps. Gentle surfactant system, good for calm-phase maintenance when you don’t need something medicated.

Curlsmith Wash and Scrub Detox Pro-biotic

Probiotic and apple cider vinegar base, clean surfactants. Interesting option if you want something that also addresses scalp microbiome balance rather than just cleansing.

The Ordinary Sulphate 4% Cleanser for Body and Hair

Fragrance-free, stripped-back formula. One of the lower-risk non-medicated options. Useful when your scalp is irritated and needs the most neutral cleanse possible.

Additional options worth checking (all screened well but always verify current INCI): Bumble and bumble Thickening Volume Shampoo, Bumble and bumble Sunday Clarifying Shampoo, Redken Amino-Mint Scalp Shampoo, Living Proof Clarifying Detox Shampoo, Color Wow Color Security Shampoo, milk_shake purifying blend shampoo (also contains piroctone olamine).

Scalp Treatments and Leave-On Toners

Shampooing treats the symptoms when you wash. Leave-on treatments keep Malassezia in check between washes – this is where the real long-term management happens. If you’re only using shampoo and nothing between washes, you’re leaving a gap.

Exfoliating scalp treatments

Philip Kingsley Flaky Itchy Scalp Toner

My desert island scalp product. Piroctone olamine and salicylic acid, applied at night directly to the scalp, don’t rinse. Consistent use is what got my scalp from constant background irritation to actually manageable. Not an overnight fix – it’s the sustained use that makes the difference. Non-negotiable in my routine and the first thing I’d tell anyone to try if they’re just starting to figure this out.

The INKEY List Salicylic Acid Exfoliating Scalp Treatment

Pre-wash treatment that lifts stubborn flakes and reduces oily buildup before shampooing. Apply, leave for 10-15 minutes, then shampoo as normal. Good for the in-between days when your scalp feels congested but you’re not ready to medicate again. Formula note: contains PEG-40 Hydrogenated Castor Oil as an emulsifier, which Sezia will flag. It sits low in the ingredient list and this is a rinse-off product, so the real-world risk is minimal – but run the current INCI through Sezia yourself before buying.

The INKEY List Glycolic Acid Exfoliating Scalp Scrub

Glycolic and salicylic acid combined with physical exfoliation in one step. Good for removing buildup before a medicated wash – don’t use it on a broken or actively inflamed scalp. Formula note: the physical scrub beads are made from Hydrogenated Castor Oil, and PEG-40 Hydrogenated Castor Oil also appears in the base – both will flag on Sezia. It’s a rinse-off product and contact time is short, which reduces the practical risk, but it’s not a clean screen. If you’re very Malassezia-reactive, run it through Sezia first and make the call yourself.

Aveda Scalp Solutions Exfoliating Scalp Treatment

More cosmetic than clinical, good for calm maintenance phases when your scalp is stable and you just want to keep it that way. Not for active flares.

The Ordinary Salicylic Acid 0.5% Body Serum

Yes, it says “body” right there on the bottle. No, that doesn’t actually stop it working on your scalp (skincare marketing categories are more of a suggestion than a rule, in my experience). The formula is about as stripped-back as it gets: water, propanediol, sarcosine, salicylic acid, glycerin, cocamidopropyl dimethylamine, citric acid, phenoxyethanol, chlorphenesin. That’s the whole list. No oils, no fatty acid esters, nothing in there for Malassezia to throw a party with – it screens completely clean on Sezia. Apply it to the scalp the same way you’d use any leave-on salicylic treatment. The nozzle applicator actually makes it easier to target flare-prone patches than most dedicated scalp products, which says a lot about the state of scalp product design generally.

MCT oil as a pre-wash treatment

Pure C8/C10 MCT Oil (caprylic/capric triglyceride)

This one surprises people. Most oils are an immediate no for seb derm because Malassezia feeds on long-chain fatty acids. MCT oil is different. Pure C8/C10 MCT has a shorter chain length that falls outside the range Malassezia can metabolise – which means it’s one of the only oils you can actually use on a seb derm scalp without making things worse. Apply as a pre-wash treatment directly to the scalp, leave for 20-30 minutes, shampoo out properly. It helps with the tight, dry, irritated scalp feeling without feeding the yeast. Make sure you’re buying pure C8/C10 MCT and not a blend with longer-chain oils mixed in – check the label before you buy.

Leave-on calming treatments

Eucerin DermoCapillaire Calming Urea Scalp Treatment

Brilliant for tight, itchy scalp without making hair greasy. Urea is a keratolytic – it helps break down the flaky buildup that seb derm causes at the scalp surface. One of the most underrated options in this whole directory and genuinely one I’d press into people’s hands more often.

Nizoral Scalp Treatment Gel

Leave-on ketoconazole in gel form. More targeted application and more contact time than the shampoo – useful during stubborn flares when the shampoo alone isn’t shifting things fast enough.

Ducray Squanorm Lotion

Zinc pyrithione leave-on lotion, no fragrance issues. Check current UK availability – zinc pyrithione regulations changed in 2022 and stock can be inconsistent.

The Ordinary 100% Squalane

One of the very few oils you can actually put on a seb derm scalp without having a quiet crisis about it afterwards. Squalane is a hydrocarbon – not a fatty acid, not a fatty ester. That distinction matters because Malassezia feeds on long-chain fatty acids, and squalane sits completely outside that range. The INCI is one ingredient: Squalane. It screens completely clean on Sezia. I use it post-shower, directly on the scalp, on days between washes – a few drops worked in with fingertips. It handles that tight, dry, papery scalp feeling without triggering a flare. No grease, no smell, no drama. It’s not a treatment – it won’t kill Malassezia or shift active flakes, that’s what your antifungal shampoo and leave-on toner are for – but as a post-shower emollient for the gaps between washes, it does the job. Available on Lookfantastic (use code LFTFNEVEEN for 20% off). One of those things I genuinely wonder why I didn’t try sooner, honestly.

The Ordinary Multi-Peptide Serum for Hair Density

Fragrance-free, lightweight leave-on serum. Good if you’re managing hair thinning alongside seb derm and want something that supports both without feeding Malassezia. Not a treatment for the seb derm itself – more a supportive addition once things are stable. Formula note: PEG-40 Hydrogenated Castor Oil and Polysorbate 20 appear at the tail end of the list as solubilisers and will flag on Sezia, but both are at very low concentrations. Always verify the current INCI before buying.

---

Conditioners

The trickiest category. Most conditioners contain fatty esters or plant oils that feed Malassezia – and the ones that work best for hair are often the worst for a seb derm scalp. Always run the current INCI through Sezia before committing. Apply to lengths and ends only, avoid the scalp entirely wherever possible. The options below tend to screen better than most but formulas change – verify before buying.

Color Wow Color Security Conditioner

Primarily amodimethicone and quat-based conditioning, which is a better starting point than most conditioners for seb derm. That said, the current formula does contain Avocado Oil (Persea Gratissima) and Diheptyl Succinate, both of which Sezia will flag. It’s mid-list so concentration is relatively low, and this is a lengths-only rinse-off product – but it’s not a clean screen, and calling it Malassezia-safe without caveats would be misleading. Apply to lengths and ends only, never the scalp, and verify the current formula with Sezia before buying.

CeraVe Conditioner with Zinc Pyrithione

Most conditioners in this section earn their place by not being actively terrible for a seb derm scalp. This one does something the others don’t. The zinc pyrithione in the formula is an actual antifungal active – it directly targets Malassezia rather than just hoping to avoid feeding it, which puts it in a completely different tier from everything else in this category. Apply to lengths and ends only, never the scalp. That’s non-negotiable regardless of what the active ingredient is doing. And run the current INCI through Sezia before buying – CeraVe conditioners contain ceramides and other ingredients that may flag, and zinc pyrithione doesn’t cancel those out on a Malassezia screen. But if you’ve been looking for a conditioner that does more than just play defence on the hair shaft, this is worth knowing about. Check Amazon UK for current availability.

Stylers

Gels, sprays, and mousses are generally the most Malassezia-conscious styling options because they’re typically polymer and silicone-based rather than oil or butter-based. Color Wow has the most consistently clean range for seb derm. Avoid anything heavy, creamy, or oil-based at the scalp – if it feels like it’s coating your scalp, it probably is.

Color Wow Dream Coat Supernatural Spray

Humidity-blocking treatment spray. Screens clean, no problematic esters.

Color Wow Raise the Root Thicken and Lift Spray

Root-lifting spray. Good for thinning hair alongside seb derm – adds volume without oiliness at the scalp.

amika Perk Up Dry Shampoo

One of the cleaner dry shampoos for seb derm. Avoid letting dry shampoo build up on the scalp – always clarify properly before your next medicated wash.

K18 AirWash Dry Shampoo

Lightweight, no powder residue. Screens reasonably well for Malassezia. Verify current INCI before buying.

What actually made the biggest difference

Not any single product. The habits around the products. Rotating shampoos instead of using one constantly. Leaving medicated shampoo on long enough (three to five minutes – set a timer, you will not naturally stand there long enough without one). Using leave-on scalp treatments between washes rather than just relying on shampoo. Stopping random oils. Prioritising barrier repair during flares rather than throwing more actives at an already-inflamed scalp.

The Philip Kingsley toner at night is the one thing I’d single out if someone asked me what changed things most. Consistent leave-on treatment between washes, not just shampooing every few days and hoping. That’s the gap most people are missing.

FAQ

The questions I get asked most in the comments and DMs on this one.

What’s the single best product to start with for scalp seb derm?
Nizoral 2% ketoconazole shampoo. If you buy nothing else off this whole list, buy that. Leave it on for three to five minutes, not the usual thirty-second rinse-and-run.

How long do you actually leave ketoconazole shampoo on for?
Three to five minutes, every time. I know that feels like forever standing in the shower doing nothing, which is exactly why I set a timer on my phone. Rinsing it out after thirty seconds like a normal shampoo basically wastes it.

Is it actually safe to put any oil on a seb derm scalp?
Most oils, no, they’re exactly what Malassezia wants to eat. But squalane and pure C8/C10 MCT oil are the two exceptions, the chain length is different so the yeast can’t use them. Everything else I’d run through Sezia first.

Do I need to rotate shampoos or can I just stick to one?
Rotating genuinely helps, it reduces the chance of Malassezia adapting to whatever you’re using. I keep a ketoconazole one, a gentler maintenance one, and sulfur in reserve for stubborn patches, and swap between them rather than living on just one.

What’s the actual difference between dandruff and seb derm?
Same yeast, different severity. Dandruff is dry white flakes and not much else going on. Seb derm is oilier, yellower flakes with proper redness and inflammation, and it can spread to your face and eyebrows too. If it’s just flaking, dandruff shampoo might do it. If your scalp is angry as well as flaky, that’s seb derm territory.

Before you buy anything, run it through Sezia. Paste the ingredient list in, get a first-pass screen. Thirty seconds. Not infallible but a genuinely useful starting point. And if there’s something that’s worked for your seb derm scalp that isn’t on this list, leave it in the comments – I read them all.
