Thick Plaques. Burning Itch.
A Scalp That Never
Fully Clears.
More than half of people with plaque psoriasis have scalp involvement, and the scalp is among the hardest sites to treat because hair gets in the way of everything.1 This plant-based 9-component system works on scale, the scalp microbiome and the barrier — as scalp care to use alongside medical treatment, not in place of it. No coal tar. No steroids. No prescription.

You Stop. It Comes Back.
The standard path for scalp psoriasis is well-worn: coal tar or salicylic acid shampoos, escalating to a prescription topical steroid, then perhaps roflumilast foam, and biologics if nothing holds. Each of those works to varying degrees — and each of them is a legitimate treatment this page is not arguing against.
The reason nothing holds permanently is that psoriasis is a systemic immune-mediated disease. The inflammatory pathway driving your scalp plaques is the same one associated with psoriatic arthritis and cardiovascular disease. No topical — pharmaceutical or botanical, ours included — changes that. What a good scalp routine can do is make the surface more manageable day to day while your doctor manages the disease.
Important. Psoriasis is a systemic immune-mediated disease and should be diagnosed and managed by a physician or dermatologist. This page is educational information about cosmetic scalp care. It is not medical advice, and nothing here is intended to diagnose, treat, cure or prevent any disease. Individual results vary. Do not stop a prescribed treatment without speaking to whoever prescribed it.
Why Scalp Psoriasis Is Harder
Than Psoriasis Anywhere Else
Scalp psoriasis shares the same immune mechanism as plaque psoriasis elsewhere — accelerated keratinocyte turnover producing skin cells in days rather than the usual weeks, creating the thick silvery plaques. But the scalp adds practical problems that make it stubborn in ways the rest of the body isn't.
A 2025 network meta-analysis of scalp psoriasis randomized trials found that scalp psoriasis is often resistant to topical and conventional systemic agents, and that there is no consensus gold-standard treatment.3 We're quoting that because it cuts both ways: it explains why you've struggled, and it means nobody — including us — should be promising you a solved problem.
Standard Scalp Psoriasis Treatments
vs. Plant-Based Scalp Care
| Approach | Category | What it does | Considerations |
|---|---|---|---|
| Coal tar shampoos | OTC drug | Slows cell turnover, reduces scaling. FDA-monographed as safe and effective at 0.5–5% | Strong odor; can stain and discolor light hair; poor long-term compliance. Note the EU bans coal tar in cosmetic products entirely⁴ |
| Salicylic acid shampoos | OTC drug | Keratolytic — loosens and removes scale buildup | Scale removal only; can be drying or irritating if overused; no anti-inflammatory action of its own |
| Topical corticosteroids (e.g. clobetasol shampoo) | Prescription drug | Potent anti-inflammatory — fast, effective clearance in moderate-to-severe cases | Prescription only; potency and duration need medical supervision; skin thinning with prolonged use; flare on stopping |
| Roflumilast foam 0.3% | Prescription drug | Non-steroidal PDE-4 inhibitor. FDA-approved May 22, 2025 for scalp and body plaque psoriasis, ages 12+, on trials of 736 patients¹ | Prescription only; newer, so less long-term data; adverse events in trials were low and mostly mild — headache, diarrhea, nausea¹ |
| Biologics | Prescription injectable | Targeted immune therapy — the only category that acts on the systemic driver, and the most effective option for moderate-to-severe disease | Specialist-managed injection; significant cost; immunosuppression and infection risk; reserved for moderate-to-severe disease |
| Kapyderm Scalp Psoriasis Treatment | Cosmetic scalp care + supplements | Scale softening, scalp microbiome and barrier support, plus botanical supplements | Not a drug, and not a treatment for psoriasis itself. No controlled trial of this system exists and it has not been compared with any of the above. |
This compares categories rather than brands. Everything above works — the table is about scope and trade-offs. If your psoriasis is moderate-to-severe, a dermatologist has options here that no cosmetic routine can match.
Psoriasis Is Systemic.
The Scalp Is Where It Shows.
The same inflammatory process behind your scalp plaques is associated with a documented set of systemic conditions. We're including this because it's the most important thing on the page — and it argues for seeing a physician, not for buying a supplement. No scalp product addresses any of the following.
The Scalp Psoriasis Home Treatment
9 components — 7 topical, 2 internal. Plant-based cosmetic scalp care formulated under EU cosmetic regulation. No coal tar, no corticosteroids, no prescription required.
Depure and Revital are dietary supplements. These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease. Check with your physician before starting a supplement, particularly if pregnant, breastfeeding, or taking prescription medication — including biologics or other systemic psoriasis treatment. Patch-test topical products before wider use.
Two-Phase Routine
Phase 1 focuses on softening and clearing scale. Phase 2 shifts to maintenance. You move between them as your scalp changes — and because psoriasis relapses, expect to move back and forth over time rather than finishing.
- Morning, afternoon & evening: Apply KS115 to plaque areas → then Essential Oil K1 → finish with Special K Cream
- Daily wash: Mix Dandruff & Dry Hair Base Cleanser + Ampoule N → apply, leave several minutes, rinse
- Internal — morning: Take 2 Depure capsules
- Internal — afternoon: Take 2 Depure capsules
- Internal — evening: Take 2 Revital capsules
- Replace KS115 with Fungi-Activ + Base Tonic, applied with Special K Cream and Essential Oil K1 — daily
- Continue the daily wash with Dandruff & Dry Hair Base Cleanser + Ampoule N
- Continue the supplement cycle (Depure + Revital)
Stop and speak to your doctor if your scalp becomes painful, weeping, or infected-looking, or if plaques spread rapidly. Psoriasis flares can need medical treatment that a scalp routine cannot provide.
