Most of us give the face ten minutes and the scalp about thirty seconds. In Korea that order is reversed. The scalp is treated as skin, and given a routine that looks almost identical to a facial: cleanse, exfoliate, treat, soothe.
This one is for everyone, by the way. Korean scalp care is not a women’s aisle — a lot of it is aimed squarely at men, and a lot of it at people in their twenties who have not noticed anything wrong yet.
First, the scanning thing
You have probably seen the videos: someone in a reclining chair, a camera the size of a torch pressed against their parting, and a hugely magnified image of their own scalp on a screen beside them — pores, flakes, and a count of how many hairs are coming out of each follicle.
That is a Korean head spa, and the boom is real. According to the Korea JoongAng Daily, booking transactions rose 219% between November 2024 and November 2025, with 58% of reservations coming from English-speaking countries. A premium eighteen-step package in Seoul runs to about £115 for ninety minutes and includes scalp diagnosis, cleansing and exfoliation, a waterfall rinse and red-light therapy. Olive Young, Korea’s biggest beauty retailer, has put scalp cameras in its flagship stores.
The scan is useful, and it is limited. Under high magnification a technician can see how many hairs share a follicle, how much oil and dead skin have built up, whether pores are blocked or empty, and whether the skin is red. What the camera cannot do is tell you why — it cannot see your genetics, your iron levels or your thyroid, and it cannot tell you which treatment will work for you.
If you have had one done and walked out with a photo and a recommended package, keep the photo. A scan makes an excellent before-and-after, and it is the best argument there is for actually sticking to a routine for three months.
Your scalp is among the oiliest skin you own
The scalp is not a separate organ. It is skin, with a barrier to look after like any other, and roughly 100,000 hair follicles pushed through it. It also carries one of the highest concentrations of oil glands on the body: a 2018 paper in Scientific Reports puts sebaceous gland density on the scalp and forehead at 400–900 glands per square centimetre, against a fraction of that on the arms and legs.
That oil feeds a resident microbiome, and the balance of it matters. A 2024 review in the journal Cosmetics reports that on a healthy scalp Malassezia yeasts make up around 46% of the microbial population, with Cutibacterium acnes at about 26%. On a scalp with dandruff, Malassezia climbs to roughly 74% while C. acnes falls to about 6%.
So a flaky, itchy, greasy scalp is rarely a hair problem. It is a skin problem happening somewhere you cannot see.
The Korean idea: treat the scalp like a face
Korean haircare is built around 두피 스케일링 (dupi scaling, or “scalp scaling”) — removing built-up oil, dead skin and product residue so that whatever goes on afterwards can reach the skin. Same logic as exfoliating your face before a serum.
It happens at two levels. In dermatology clinics, scaling is a clinical treatment often combined with radiofrequency or oxygen therapy, at roughly £30–60 an hour — cheaper, and a good deal more medical, than the spa version. At home, it is a salicylic-acid shampoo and a leave-on scalp tonic, used consistently.
The appetite is not a marketing invention. Korean haircare exports hit US$478 million in 2025, up 15.7% on the year before (Korea Customs Service), and Olive Young reports haircare as its fastest-growing category.
Men, this is not a women’s routine
Korea’s Health Insurance Review and Assessment Service recorded 241,217 people treated for hair loss in 2024. Men were 57% of them and women 43%. More striking is the age: people in their twenties and thirties made up 37.6% of the total, and the thirties group (51,619) is now larger than the fifties group (46,913).
The shops have followed. Olive Young’s “special care” hair range grew 151% in a year, and scalp shampoos and tonics now sit at eye level in every branch rather than tucked away.
None of that is because Korean men have worse hair. It is because the cultural script there treats a scalp routine as ordinary maintenance, like brushing your teeth, rather than an admission of anything. That is a better script than ours, and it is the one part of this you can copy for free.
What Korea legally lets a shampoo say
Korea has a regulated product category the UK does not: 기능성화장품 (functional cosmetics). One recognised claim within it is “탈모 증상 완화에 도움을 주는 화장품” — roughly, a cosmetic that helps with the symptoms of hair loss. To carry it, a product must contain one of two combinations of actives set out by the Ministry of Food and Drug Safety, at defined levels:
| Combination | Actives and levels |
|---|---|
| Option 1 | Dexpanthenol 0.1% · Salicylic acid 0.25% · L-menthol 0.3% |
| Option 2 | Niacinamide 0.3% · Dexpanthenol 0.5% · Biotin 0.06% · Zinc pyrithione solution (50%) 2% |
And what each of those is actually doing:
| Ingredient | Role on the scalp |
|---|---|
| Salicylic acid | Oil-soluble, so it works inside the pore — loosens the plug of sebum and dead skin rather than sitting on top of it |
| Dexpanthenol (pro-vitamin B5) | Hydrates and supports the scalp barrier |
| L-menthol | Cools; makes a hot, itchy scalp comfortable |
| Niacinamide | Supports the barrier and helps with irritation |
| Zinc pyrithione | Long used against the yeasts behind dandruff — but see the note below |
| Biotin | In the standard, though the evidence for biotin in people who are not deficient is weak |
Why this is worth knowing as a shopper: it explains why salicylic acid, dexpanthenol and menthol keep turning up together in Korean scalp products. It is not a house blend somebody invented for the marketing — those three are written into a national standard, at stated levels, which is more than most bottles anywhere can say.
Myth: an anti-hair-loss shampoo will regrow your hair
It will not, and Korean media has been the loudest voice saying so.
In 2017 the Ministry of Food and Drug Safety (식품의약품안전처) moved these products down from quasi-drug status to functional cosmetics. Investigating the category in 2021, Kyunghyang Shinmun calculated that the actives make up only around 0.65% to 2.56% of a 400–500ml bottle — and pointed out that shampoo sits on the scalp for about ninety seconds before being rinsed away.
The products are honest about it themselves. On the back of a Korean scalp shampoo you will find the mandatory line 질병의 예방 및 치료를 위한 의약품이 아님 — “this is not a medicine for the prevention or treatment of disease”. And a Seoul clinician quoted in the pharmacy press was blunt about professional scaling too: it manages the scalp, it does not reverse anything, and nothing visible happens in under three months.
Myth: washing your hair often makes it fall out
We lose between 50 and 100 hairs a day without noticing (NHS). On a healthy scalp roughly 85% of follicles are actively growing at any moment and about 15% are resting, and resting hairs come away whenever the hair is disturbed. Wash twice a week instead of daily and you simply collect three days’ worth of shedding in one drain. Washing more often does not make you lose more hair overall — it just spreads it out.
When shedding genuinely increases, it is often telogen effluvium: a fever, an operation, childbirth, a crash diet, a thyroid change or a stretch of real stress pushes an unusual number of follicles into the resting phase at once. The tell is the delay.
Shedding becomes noticeable two to four months after the trigger, peaks, then settles over roughly six to nine months (DermNet). It does not cause baldness. It also means the thing you are blaming today — a new shampoo, a recent haircut — is almost certainly not the cause.
When it is not a scalp-care problem
Please see a GP rather than a shop if any of this applies:
- Your hairline is receding, or you are thinning at the crown or through the parting in a pattern — the treatments with real evidence behind this are medical ones your GP can talk you through, and a shampoo is not a substitute for them
- Hair is coming out in defined round patches
- The scalp is sore, scaling thickly, weeping or bleeding
- Shedding is still heavy after nine months, or getting worse rather than settling
- You are also unusually tired, cold or breathless — iron and thyroid problems can show up in your hair, and both are a simple blood test
The NHS is clear that no hair-loss treatment is 100% effective, and that most only work for as long as you keep using them. Knowing which kind of hair loss you have is worth more than any product decision, and it is the one thing a head-spa camera cannot give you.
Building the routine: what we would actually use
Cleanse, exfoliate, treat, soothe — the four steps in the chart further up, on two or three wash days a week. Two or three is simply where most people land; wash more often if your scalp is oily, since as we have just covered, frequency is not what costs you hair. You do not need all of it — start with the shampoo and one leave-on.
If your scalp is oily and greasy by day two
SOME BY MI Cica Peptide Anti Hair Loss Derma Scalp Shampoo — 285ml, £21
- Salicylic acid to lift oil and buildup, with peptides and centella (cica) to keep the skin comfortable while it does
- A proper scalp shampoo rather than a hair shampoo — the difference is where you put it
- Massage into the scalp, not the lengths, and give it a full minute before rinsing
If you want a daily leave-on step at the roots
SEAPURI Scalpy Hair Serum — 20ml, £16.50
- Salicylic acid to clear the pore, dexpanthenol to hydrate, menthol to cool it down
- Roller applicator, so it lands on the scalp rather than the hair; work along the parting and hairline
- Used every day, not only on wash days. The easiest one to keep up with if you are new to this
SOME BY MI Cica Peptide Anti Hair Loss Derma Scalp Tonic — 150ml, £19
- The larger-format option if you want to cover the whole scalp rather than target a parting
- Menthol and cica; the one to reach for after a hat, a helmet or a long day indoors
Both of those, and everything else in this family, sit in our Korean hair serums and scalp tonics.
If you are flaky, itchy or wearing a lot of dry shampoo
SEAPURI Scalpy Bubble Tonic — 100ml, £20
- A micro-bubble scaling step — the closest thing at home to the exfoliating part of a Korean head spa
- Salicylic acid and menthol to loosen buildup; once a week is plenty
SOME BY MI Cica Peptide Anti Hair Loss Derma Scalp Treatment — 50ml, £14
- Three minutes on the scalp after shampooing, with cica to settle irritation and flaking
- A small size, so a sensible way to find out whether the range suits you before you commit
If your hair is fine and falls flat rather than thinning
HEIMISH RX Amino Biotin Revitalizing Shampoo — 400ml, £21
- The biotin is in the name; the light amino-acid base is why we like it. It cleans thoroughly without leaving fine hair weighed down
- The right choice if your issue is limpness and grease rather than shedding
If the scalp needs help and the lengths are damaged too
COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Shampoo — 200ml, £24
- Worth understanding, because the word “peptide” is doing two completely different jobs on this page. The peptides in the scalp products above are aimed at the skin. Tripeptide-132 here binds to keratin — it is working on the hair shaft, not the roots. Same word, different target
- The scalp side is real too: piroctone olamine for flakes, zinc PCA for oil, caffeine, panthenol and niacinamide, plus five ceramides for the barrier
- And a neat detail after the note above — piroctone olamine is the anti-flake active that is permitted here, so this is a Korean brand formulating for markets like ours rather than around them
- Low pH, so it cleans without roughing up the cuticle. The one to pick if bleach, colour or heat is part of the picture as well as the scalp

How to actually use it on a wash day
- Wet thoroughly. A full minute of water alone removes a surprising amount of oil and product.
- Shampoo the scalp, not the lengths. If you use styling products or dry shampoo, a second short wash is what actually reaches the skin. Fingertips, never nails.
- Leave it on. Salicylic acid needs contact time — give it a minute before rinsing.
- Conditioner or mask on the lengths, not the roots, unless it is a scalp treatment.
- Tonic or serum onto a towel-dried scalp, in sections along the parting, then massage for a minute. This is the one step that is not wash-day only — a leave-on serum goes on daily.
- Dry the roots properly. A scalp left damp under a towel or a hat all evening is warmer and wetter than it needs to be.
The short version
Your scalp is skin, and it behaves like skin: it gets oily, congested, dry and irritated, and it responds to being cleaned and left comfortable. That is the whole of the Korean idea, and it is worth borrowing.
What it is not is a treatment for hair loss. Korea regulates that distinction more carefully than we do, and still tells you on the back of the bottle that it is not a medicine. So use the routine for what it really does — and if something has changed in a way that worries you, book the GP rather than another bottle.
Give it twelve weeks before you judge it. That is roughly how long a follicle takes to respond to anything, and it is the same three-month window Korean clinicians quote. If you did get a scan photo, that is when to take the second one.
Not sure whether your scalp is oily, sensitive or just neglected? Our skin assessment takes two minutes and we will send you a routine built around your answers.
