Ayurvedic hair care · Traditional knowledge
दारुणक — the classical term for the dry, itching, flaking scalp. Sushruta places it among the Kshudra Roga, the minor disorders.
Flaking is a symptom, not a diagnosis.
Several quite different conditions produce a scalp that sheds and itches, and one of them needs a prescription medicine that no topical preparation can substitute for. That is the first thing this page has to say, and it comes before the Sanskrit.
What follows is the Ayurvedic account of Darunaka as the classical texts give it — the signs they list, the doshas they name, the causes they blame, and the treatment they prescribe. It is a description of a traditional system. It is not a claim about anything we sell.
The terms used on this page
One
Before any of the classical material is useful, it is worth knowing what else produces the same appearance. These are distinctions a dermatologist makes by looking, and they are not ones you can reliably make from a photograph or a description.
| Condition | How it typically presents | Why it matters |
|---|---|---|
| Dandruff | Fine, loose white or grey flakes. Itching. No redness | Generally managed with medicated shampoos containing specified active ingredients |
| Seborrhoeic dermatitis | Redness with greasy yellowish scale. Can extend to eyebrows, the sides of the nose, behind the ears | Widely regarded as the same process as dandruff at greater severity. Usually needs treatment rather than washing |
| Scalp psoriasis | Thick, silvery, sharply defined plaques, often extending past the hairline onto the forehead or neck | A different disease with different treatment. Can be part of psoriasis elsewhere on the body |
| Tinea capitis | Scaling with patchy hair loss and hairs broken off short. Sometimes a boggy, tender swelling | A fungal infection that requires oral antifungal medication. Topical preparations do not reach it. It is contagious, and can scar the follicle |
The one to rule out
Tinea capitis is the reason this section exists. The fungus grows within the hair shaft itself, which is why creams, shampoos and pastes — herbal or otherwise — do not clear it. It needs a systemic medicine, prescribed.
It is most common in children, it spreads between people and sometimes from animals, and if it is left it can destroy follicles permanently. Scaling together with patchy hair loss, or with hairs broken off close to the scalp, is a reason to be seen rather than a reason to try something else.
Contact dermatitis — a reaction to something applied to the scalp — also produces itching, redness and flaking. The cause can be a shampoo, a styling product, an essential oil, or a hair colour.
That includes ours. Our shampoo bar contains lavender oil, a recognised contact allergen, and almond oil, a tree nut. Our colours are plant material, and people can react to plant material. If flaking or itching began after starting something new, the new thing is the first suspect, and it does not become less of a suspect because it is natural.
None of this means a flaking scalp is necessarily serious. Most of it is ordinary dandruff, and ordinary dandruff is common, harmless and manageable. But “most” is doing real work in that sentence, and the classical material that follows is more interesting if you already know what it is and is not describing.
Two
The classical description of Darunaka is short and specific. It lists five signs, and two of them are not in any modern description of dandruff at all.
| Sanskrit | Meaning | Named by |
|---|---|---|
| Kandu | Itching of the scalp | Sushruta, Madhava, Yogaratnakara, Vagbhata |
| Rukshata | Dryness and roughness — given as Keshabhoomi Rukshata, dryness of the ground of the hair | Sushruta, Madhava, Yogaratnakara |
| Twak Sphutana | Cracking or fissuring of the skin | Sushruta |
| Keshachyuti | Falling of the hair | Vagbhata |
| Swapa | Numbness — loss of sensation in the scalp | Vagbhata |
The two that give us pause
Numbness is not a feature of dandruff as the word is normally used. Nobody buying an anti-dandruff shampoo is doing so because their scalp has lost sensation. Yet Vagbhata lists Swapa among the signs, in a literature that does not pad its descriptions.
And hair fall is not a feature of dandruff either, though it appears constantly in modern marketing about it. Vagbhata names Keshachyuti directly.
We do not know what to make of either, and we would rather say so than construct an explanation. An honest reading is that the texts were describing something, and we cannot be certain it is the thing we call dandruff.
Almost every source that discusses Darunaka translates it as dandruff, and then proceeds as though the two words were interchangeable. They may not be.
Read the list again without the translation in mind. Itching. Dryness. Cracking of the skin. Hair falling. Loss of sensation. That is a more severe picture than fine white flakes on a collar. Several Ayurvedic academics correlate Darunaka with seborrhoeic dermatitis rather than with cosmetic dandruff, and reading the lakshanas, it is easy to see why.
This matters for a practical reason. If Darunaka describes something closer to seborrhoeic dermatitis, then the classical treatment for it was aimed at a medical condition — which is consistent with what that treatment turns out to involve, and it is one more reason not to lift a paste out of it and sell it for flakes.
| Author | Placed under | What that group is |
|---|---|---|
| Sushruta | Kshudra Roga | The minor disorders — minor in prognosis rather than in significance |
| Vagbhata | Shiroroga | The disorders of the head |
The same split appears with Khalitya and with Indralupta: Sushruta grouping by severity, Vagbhata grouping by location. It is a difference in how the two authors organised medicine, not a disagreement about the condition.
What both agree on is which doshas are involved — and there the classical account becomes genuinely interesting, because it explains why a dry flaking scalp and a greasy one are given the same name.
Three
A dry, tight, powdery scalp and a greasy, heavy, sticky one look like opposite problems. In the classical account they are the same disorder, produced by the same two doshas in different proportions — and that is the most structurally interesting thing about Darunaka.
Darunaka is described as Vata-Kapha predominant. The two are opposite in character, and the texts are explicit about what each contributes.
| Dosha | Its qualities | What it produces at the scalp |
|---|---|---|
| Vata | Dry, rough, light, mobile | Impurities that are dry and scaling |
| Kapha | Soft, sticky, heavy, lubricating | Impurities that are greasy and adherent |
Aggravated, each produces waste of its own character in the skin of the scalp. Those impurities accumulate in the deeper tissue of the Keshabhoomi — the ground of the hair — and vitiate it. Itching and flaking follow from that contamination, and which kind of flaking follows from which dosha was leading.
| Dry | Oily or wet | |
|---|---|---|
| Dosha balance | Vata Pradhana Kapha — Vata leading | Kapha Pradhana Vata — Kapha leading |
| Scale | Fine, loose, powdery | Heavier, adherent, greasy |
| Scalp | Tight, rough, lacking moisture | Slick, with excess sebum |
Why this is worth noticing
The same two doshas produce both. There is no third dosha for the greasy kind and no different disease for the dry one. What changes is which of the pair is leading, and the disorder keeps its name either way.
That is a model with a genuine explanatory move in it: it accounts for two opposite appearances without needing two causes. Whether it is right about the body is a separate question, and not one we can answer. But it is a real piece of reasoning rather than a list of symptoms with herbs attached.
Some accounts add a further step, and it matters for understanding the treatment. Increase of Vata and Pitta is described as damaging Rakta Dhatu — the blood — giving rise to impurities in it, and thence to poor nourishment of the scalp.
This is why the classical treatment for Darunaka includes Siravedhana, the opening of a vessel. If the blood is held to be part of the pathology, letting some of it is the internally consistent response, and the texts prescribe it. That comes in the fifth section.
Where the authors differ
Vata and Kapha are the pair almost every source names. But not every source stops there. Videha is cited as involving Pitta and Kapha; other accounts describe all three as vitiated, with Vata and Kapha predominant.
You will also find versions — including, until recently, on this website — that assign dry dandruff to Vata and Pitta. We have not been able to trace that to a classical source, and the readings we can trace give the dry form as Vata-predominant Kapha. We have corrected it rather than leaving it.
The other account, in its own words
Modern dermatology describes dandruff as arising from the interaction of three things: sebum production, the presence of Malassezia yeasts that are part of the normal scalp flora in most adults, and individual susceptibility to the by-products of their metabolism. The yeast is present on almost everybody; what differs is the response to it.
Note that this account does not divide dandruff into dry and oily as its primary distinction. The dry-versus-oily split familiar from shampoo aisles maps onto neither system cleanly — it is a marketing category more than a clinical one, and a scalp that feels dry can be producing plenty of sebum underneath.
Two accounts, two vocabularies, arriving at a similar observed spectrum by reasoning that shares nothing. We are not going to tell you that Kapha is sebum.
Four
The Nidana for Darunaka has a feature the lists for greying and hair loss do not. Two of the causes are things not done rather than things done — and one of them is a category with no counterpart in modern medicine at all.
| Category | Cause |
|---|---|
| Ahara Diet |
Excessive intake of sour-tasting food |
| Prolonged intake of cold water, and cold water on the head | |
| Vihara Conduct |
Excessive exposure to sunshine |
| Ratri Jagarana — waking through the night | |
| Excessive sweating | |
| Exposure to dust | |
| Vega Dharana Suppression |
Suppression of the natural urges of the body |
| Omission Not done |
Not washing the hair regularly |
| Not applying oil to the scalp |
The two omissions
Most Nidana lists name excesses — too much heat, too much salt, too much sun. Here the texts also name absences. Hair left unwashed, and a scalp left un-oiled, are given as causes of the disorder in their own right.
That follows from how the system is built. Dinacharya — the daily regimen — is not a wellness supplement to Ayurvedic medicine; it is part of the medicine, and Shiro Abhyanga, oiling the head, is one of its prescribed items. Failing to do a prescribed thing is, in that framework, as much a cause as doing a forbidden one.
And one category that does not translate
Vega Dharana is the suppression of the natural urges — the body’s involuntary calls, held back rather than answered. Ayurveda treats this as a cause of disease across a wide range of conditions, and devotes considerable space to it.
Nothing in contemporary medicine corresponds to the category. We include it because it is in the list, and because leaving out the parts that do not translate would give a false impression of how closely the two systems sit. They do not sit closely.
The classical list names not washing the hair as a cause. Modern advice about flaking scalps more often warns about the opposite — washing too often, or with something too harsh, stripping the scalp and provoking more of what you were trying to remove.
Both may be true of different people, and neither is advice we are in a position to give. We note the divergence because it is a useful check on the habit of reading old texts as though they anticipated everything. Where the two accounts point in different directions, saying so is more informative than choosing the one that flatters the tradition.
In this system, Nidana Parivarjana — removing the causes — is the first limb of treatment for anything, and it comes before medicine of any kind.
So the classical first response to a flaking scalp is not something applied to the scalp. It is the sour food, the cold water, the sun, the broken sleep, the dust, the urges held in, the hair unwashed and the head un-oiled.
We are describing what the tradition prescribes, not prescribing it. And the second limb, which the next section comes to, is where the classical approach parts company with anything sold in a jar.
Five
Ayurvedic reviews describe the management of Darunaka as multidimensional, and the word is doing real work. It means purification, the opening of a vessel, a set of procedures performed on the head, and internal medicines — alongside the removal of the causes. The paste is one item inside one of those five.
One
Removing the causes
The sour food, the cold water, the sun, the nights awake, the dust, the sweating, the urges held in — and the two omissions, the hair unwashed and the head un-oiled. Every review of Darunaka management puts this first.
Two
Purification
Purificatory therapy chosen according to which doshas are involved, preceded by oleation. Supervised clinical procedures, requiring assessment beforehand and managed recovery afterwards.
Three
Opening of a vessel — venesection
The texts prescribe the letting of blood for Darunaka, and the reasoning is internal to the system: if vitiated Rakta is part of the pathology, removing some of it is the consistent response. Section three set that out.
We include this because it is what the texts say. Leaving it out would make the classical approach to a flaking scalp sound gentler, and more like a hair mask, than it is.
Four
Local treatment — the procedures performed on the head
This is a group rather than a single thing, and the classical literature names six:
Note that washing the head appears here as a treatment, having appeared in the Nidana as an omission. The system is consistent with itself.
Five
Internal palliative medicines
Preparations taken internally, selected according to the dosha state. Not applied to the scalp at all.
Where that leaves the jar of powder
Shiro Lepa is the sixth item in the fourth of five limbs. It is a component of a component.
Extracted from that structure and sold on its own as “the Ayurvedic treatment for dandruff”, it is not the Ayurvedic treatment for dandruff. It is a paste. The tradition put it fourth for a reason, and the reason is that the tradition did not think a paste was going to do the job by itself.
Radico sells pastes and powders. We are not going to call them a treatment for anything.
Since this page previously said otherwise, it is worth stating plainly.
| Product | What it actually is |
|---|---|
| Neem leaf powder | Milled Azadirachta indica leaf. It carries no saponins, so it does not wash. Its principal leaf compound is nimbolide. We make no claim that it treats dandruff or any scalp condition, and the antifungal literature people cite concerns isolated compounds in laboratory conditions rather than milled leaf on a scalp. |
| Methi seed powder | Milled fenugreek seed. Mixed with water it forms a slippery gel — that is galactomannan, a polysaccharide, and it is a physical property you can verify in a bowl. It is not an antibacterial treatment for flakes. |
| Organic Shampoo Bar | A true soap, pH 9.35. Not a gentle product and not for a dry or irritated scalp — its job is stripping silicone residue before a plant colour. Not for daily use, not within 72 hours of colouring, and it contains lavender oil and almond oil. |
If your scalp is flaking and irritated, the honest answer is that we do not have the right product for you, and the right next step is a diagnosis rather than a purchase.
We are not Sanskritists, and we have not read the Samhitas in the original. This page is built from reviews and journal articles by Ayurvedic academics who have. Where those reviews disagree with one another — on which doshas are involved, on whether Darunaka corresponds to dandruff or to seborrhoeic dermatitis — we have given the variation rather than choosing.
One caveat we should state. The Nidana list in section four is drawn partly from practitioner sources and reviews that do not all cite chapter and verse. We have not verified every item against a primary text, and we would rather flag that than present the list as more settled than it is.
Principal sources consulted
If we have any of this wrong, we would like to know. Write to laboratory@radicousa.com. Corrections to this page are as welcome as corrections to anything else on this site, and we will make them in public rather than quietly — as we have done in section three.
This page describes a traditional system of medicine for general interest. It is not medical advice, not a diagnosis, and not a treatment claim for any Radico product. Radico makes cosmetics; none of our products is intended to diagnose, treat, cure or prevent dandruff, seborrhoeic dermatitis, psoriasis, fungal infection or any other condition. A scalp that is persistently flaking, itching, red or sore — and particularly one with patchy hair loss or hairs broken off short — should be assessed by a doctor. Several of the conditions that present this way have effective treatments, and one of them requires a prescription medicine that nothing applied to the surface can replace.
