Greasy Flaking. Stubborn Plaques.
Redness That Keeps Coming Back
No Matter What You Try.

Seborrheic dermatitis is chronic — not because there's no solution, but because most treatments only address one layer of a three-layer problem. This plant-based home system targets Malassezia overgrowth, barrier dysfunction, and internal inflammation simultaneously.

You've been here before

You've Tried the Medicated Shampoos.
It Comes Back Every Time You Stop.

Seborrheic dermatitis doesn't go away because ketoconazole or selenium sulfide temporarily suppress the Malassezia yeast — and then the condition rebounds when you stop. This is by design of the condition, not a failure of the product. SD is chronic and relapsing. The 2026 expert consensus now formally recommends a maintenance strategy — not just episodic flare treatment — because stopping treatment is the primary driver of relapse.1

The reason is that seborrheic dermatitis isn't purely a fungal problem — it's a convergence of three factors working simultaneously: Malassezia overgrowth, skin barrier dysfunction, and dysregulated immune response. Treating only one of them is why the others keep driving relapse.

2026 Expert Consensus — Key Update

Maintenance dosing is now a formal clinical recommendation, not an afterthought. The 2026 international dermatology consensus explicitly states: the goal is a proactive maintenance strategy that prevents relapse — not just treating active flares until clearance, then stopping. This is why the Kapyderm system includes both an active protocol and a distinct weekly maintenance wash step.1

✦Greasy, yellowish flakes — different from dry dandruff
✦Redness or rash on scalp, eyebrows, nose folds, or ears
✦Stubborn plaques or crusts that are difficult to remove
✦Intense itching — worse after sweating or stress
✦Symptoms improve with medicated shampoo, then return
✦Condition on face as well as scalp — nose, brows, ears
✦Flares triggered by stress, cold weather, or hormones
✦More than one medicated shampoo tried without lasting relief
3–5% of the global adult population has seborrheic dermatitis — rising to 85% in immunocompromised patients²
Chronic by nature — SD is a relapsing-remitting condition. Current treatments achieve only partial symptom control and are frequently followed by relapses¹
3 Factors drive seborrheic dermatitis: Malassezia dysbiosis, skin barrier dysfunction, and immune dysregulation — all three must be addressed³
The clinical picture — 2025 research

Why Seborrheic Dermatitis
Keeps Coming Back

The most current understanding of seborrheic dermatitis, published in a major 2025 review in Biomedicines, reframes the condition away from "just a Malassezia problem" toward a more complete model: Malassezia overgrowth is the trigger, but immune dysregulation and skin barrier dysfunction are what allow it to cause disease — and both must be addressed for lasting improvement.

2025 Research Consensus — Biomedicines

"Emerging evidence indicates that immune dysregulation and skin barrier function are likely central to SD pathogenesis, with Malassezia playing a secondary associated role... Malassezia overgrowth may be significant only in individuals predisposed by variations in sebaceous gland function, immune response, and lipid composition."⁴

This reframing is exactly why shampoo-only approaches have a ceiling: they suppress Malassezia temporarily but don't address the dysregulated immune response or the barrier dysfunction that allowed the overgrowth to cause symptoms in the first place. A complete approach targets all three layers — and adds an internal component to address the systemic inflammatory environment that no topical can reach.

Why three layers — not one

Each Component in This System
Addresses a Different Driver

The Kapyderm Seborrheic Dermatitis system was built around the complete clinical picture — not just the fungal surface presentation that medicated shampoos target.

Layer 01
Plaque & Scale Dissolution
Stubborn dermal plaques and crusts must be physically broken down before any antifungal or anti-inflammatory active can reach the affected tissue beneath. KS115 handles this first step that most treatment systems skip entirely.
Layer 02
Malassezia & Microbiome Rebalancing
Fungi-Activ targets the Malassezia overgrowth that drives surface symptoms — while the Dandruff Base Cleanser regulates the scalp microflora and sebum environment that allows it to overgrow in the first place.
Layer 03
Barrier Repair & Hydration
K1 and K2 Tonics restore the hydro-lipid balance specific to your skin type (dry vs. oily), while Special K Cream seals structural lipid gaps in the barrier — addressing the dysfunction that makes Malassezia pathogenic.
Layer 04
Internal Inflammation Support
Revital Supplement addresses the systemic inflammatory environment internally — targeting the immune and nutritional component that no topical treatment can reach, and that research increasingly identifies as central to SD chronicity.

Standard Approaches vs.
A Complete Three-Layer System

ApproachWhat it targetsWhat it misses
Head & Shoulders (zinc pyrithione) Antifungal — suppresses Malassezia surface growth Barrier dysfunction; internal inflammation; plaque dissolution; returns on discontinuation
Nizoral (ketoconazole 1%) Strongest OTC antifungal — directly inhibits Malassezia Barrier repair; internal inflammation; chronic relapse without maintenance rotation; side effect potential with long-term use
Selsun Blue (selenium sulfide) Antifungal + sebum reduction Scalp discoloration risk; dries scalp; no barrier repair; no internal component
Topical corticosteroids Anti-inflammatory — fast symptom relief Skin thinning with long-term use; rebound flare on discontinuation; no antifungal component
Roflumilast foam 0.3% (Zoryve) — Prescription PDE-4 inhibitor — non-steroidal anti-inflammatory; 2026 consensus highlights it as a steroid alternative for face Prescription only; newer, less long-term safety data; no antifungal component; no internal support⁵

Which presentation applies to you

Seborrheic Dermatitis
Presents Differently Across Locations

The same underlying mechanism drives all presentations. The protocol addresses all locations — though the skin-type tonic selection (K1 vs. K2) and plaque pre-treatment step vary by presentation and severity.

Most Common
Scalp Seborrheic Dermatitis (Dandruff / Seborrhea)
Greasy, yellowish flaking concentrated at the scalp — distinct from dry dandruff by texture and adhesion. May involve visible plaques at the crown or hairline. Often worsens in winter and improves in summer with UV exposure.
Facial
Facial Seborrheic Dermatitis
Redness and scaling in the nasolabial folds (nose creases), eyebrows, eyelids, and behind the ears. Often mistaken for rosacea or eczema. Requires the same antifungal-barrier-internal approach but with greater care around the eye area.
Severe
Plaque-Type Seborrheic Dermatitis
Thick, adherent, crusty plaques — most common in cases with longer duration or prior steroid use rebound. Requires the KS115 plaque pre-treatment step before any other active component can reach the affected tissue.
Men — Common
Beard & Facial Hair Seborrheic Dermatitis
The warm, moist environment beneath beard hair creates an ideal breeding ground for Malassezia. Flaking, redness, and itching along the nasolabial folds, chin, and mustache area — often bilateral. All topical components in this system can be applied to the beard area with appropriate contact time before rinsing.
Body
Chest & Sternal Seborrheic Dermatitis
The upper chest and sternal area are among the most sebum-dense body zones — commonly affected in moderate-to-severe cases. Presents as red, greasy, flaky patches along the central chest. The same topical protocol applies: Fungi-Activ + K tonic + Special K Cream to affected body areas.
Pediatric
Cradle Cap (Infantile Seborrheic Dermatitis)
A variant affecting infants with thick, yellowish scalp crusting. Generally self-resolving by 1–3 years. The Kapyderm adult protocol is not formulated for or recommended in infants — parental consultation with a pediatrician is the appropriate first step.

The Seborrheic Dermatitis Home Treatment

Kapyderm USA — Intensive Balancing & Barrier Repair System
Seborrheic Dermatitis Home Treatment
$260.91

A 7-component system targeting all three drivers simultaneously: Malassezia control, skin barrier repair, and internal inflammation support. Formulated exclusively with plant-based botanical extracts. EU-regulated — meeting cosmetic safety standards stricter than U.S. FDA requirements.

1
Dandruff Base CleanserTopical A therapeutic scalp wash that goes beyond surface cleansing — designed to clear scaling, regulate the scalp's microbial flora, and calm active itching at the follicular level. The foundation of the daily maintenance protocol.
2
KS115Topical The plaque pre-treatment step — a highly targeted formula engineered to soften and dissolve adherent dermal plaques and crusts before other actives are applied. Used when plaques are present; essential for moderate-to-severe presentations where scale buildup prevents deeper treatment from reaching affected tissue.
3
Fungi-ActivTopical A potent botanical antifungal complex that naturally controls Malassezia overgrowth and rebalances the scalp's microbial ecosystem — the plant-based equivalent of the mechanism ketoconazole performs pharmaceutically, without the chemical load.
4
K1 Tonic / K2 TonicTopical Precision skin-type-matched tonics for barrier hydration and sebum rebalancing. K1 for normal-to-dry skin profiles — restores lipid balance without adding oiliness. K2 for oily or sebum-heavy skin types — regulates excess sebum that creates the environment Malassezia thrives in.
5
Special K CreamTopical A deeply restorative barrier-repair cream that seals structural lipid gaps, accelerates tissue recovery, and locks in protective ceramides. Applied to affected areas to complete the topical barrier reconstruction after antifungal and plaque-clearing steps.
6
Ampoule NTopical A concentrated anti-inflammatory and dermal recovery serum applied to calm active irritation, reduce surface heat and redness, and support tissue repair. Used during the wash protocol to deliver concentrated actives directly to inflamed scalp tissue.
7
Revital SupplementInternal The internal component of the system — a nutritional supplement delivering vital cellular vitamins that support skin regeneration and immune regulation from within. Addresses the systemic inflammatory environment that drives SD chronicity — something no topical treatment reaches. Taken twice daily.

Frequently Asked Questions

Why does seborrheic dermatitis keep coming back after I stop using medicated shampoo?
Because seborrheic dermatitis is driven by three converging factors — Malassezia overgrowth, skin barrier dysfunction, and immune dysregulation — and most medicated shampoos only address the first. When you stop, the underlying barrier dysfunction and immune predisposition that allowed Malassezia to become pathogenic remain unchanged, so the condition rebounds. Long-term management requires addressing all three layers simultaneously and maintaining a microbiome-supportive scalp environment even after active symptoms resolve.
How is this different from Nizoral or Head & Shoulders?
Nizoral and Head & Shoulders are single-mechanism antifungal shampoos — they suppress Malassezia effectively while in use but don't repair the skin barrier, address the immune component, or provide any internal support. This system pairs botanical antifungal treatment (Fungi-Activ + Dandruff Cleanser) with plaque dissolution (KS115), skin-type-specific barrier repair (K1/K2 + Special K Cream), concentrated anti-inflammatory treatment (Ampoule N), and internal nutritional support (Revital) — targeting every layer of the condition, not just the surface.
Which tonic should I use — K1 or K2?
K1 is for normal-to-dry skin profiles — it restores hydrolipid balance without adding oiliness and is appropriate for scalp or facial SD where dryness or tight skin is a feature. K2 is for oily or sebum-heavy skin types — it regulates excess sebum production, which is often a key driver of Malassezia proliferation. If you're unsure, contact us for a free consultation and we'll guide the right selection for your profile.
Can this treat seborrheic dermatitis on my face as well as my scalp?
Yes — the system is appropriate for both scalp and facial seborrheic dermatitis. The same three-layer mechanism drives both presentations. Apply all topical components to affected facial areas (nasolabial folds, eyebrows, behind ears) with appropriate care around the eye area — Special K Cream and the tonics are formulated for skin contact, not mucous membranes.
Is this safe for long-term use?
Yes. All formulas are 100% plant-based and EU-regulated — free of the synthetic antifungal compounds and corticosteroids that carry risks with extended use. Unlike ketoconazole (liver concerns with oral use) or corticosteroids (skin thinning with topical overuse), this system is designed for the ongoing maintenance that seborrheic dermatitis's chronic nature actually requires.
How do I know if I have seborrheic dermatitis or just dandruff?
Dandruff is the mild end of the seborrheic dermatitis spectrum — typically dry, white flakes with minimal redness or itching. Seborrheic dermatitis proper involves greasy, yellowish, more adherent flakes, visible redness or rash, and commonly extends to the face (nose folds, eyebrows), ears, beard, or chest. If your flaking is accompanied by redness, involves your face, or returns despite anti-dandruff shampoo use, seborrheic dermatitis is the more likely diagnosis. Either way this system addresses both — the same Malassezia-microbiome-barrier mechanism drives both conditions, with SD the more advanced presentation.
Can I use this on my beard and chest as well as my scalp?
Yes. All topical components — Fungi-Activ, K1 or K2 Tonic, Special K Cream, and KS115 where plaques are present — can be applied to any affected area including the beard zone, nasolabial folds, chest, and sternal area. Apply with appropriate care around the eye area. Revital supplement supports skin regeneration systemically regardless of which area is affected.
