A purifying and activating ampoule for the scalp.
Concentrated botanical purification — with Methyl Nicotinate for active penetration
Kapyderm KN is a concentrated leave-in purifying ampoule from the professional Dermotricology line. Built around arnica, burdock and rosemary with salicylic acid, sulfur, and Methyl Nicotinate — a warming, circulation-activating component that confirms deep scalp penetration.
"KN is the ampoule where you feel the protocol working — the Methyl Nicotinate warming response tells you the botanicals are penetrating. That's the difference between a product sitting on the scalp and one actually reaching the tissue."
Purifying a congested scalp is one thing. Driving active ingredients into the tissue beneath it is another. Ampoule KN does both.
Kapyderm KN is a concentrated single-dose purifying leave-in ampoule from Kapyderm's professional Dermotricology line — Técnicas Capilares Profesionales. It shares the botanical base of Ampoule N — Arnica montana, Arctium majus (burdock), Rosmarinus officinalis (rosemary), salicylic acid, sulfur, and eucalyptol — with one critical addition: Methyl Nicotinate, a microcirculation activator that produces a characteristic warming or redness response. That response is the confirmation that the formula is actively penetrating the scalp tissue and driving the botanical actives where they need to go — not sitting on the surface.
The warming response — what it means and why it matters
The light warming or redness that follows KN application comes from Methyl Nicotinate — a niacin derivative that temporarily dilates scalp microvessels, increasing local blood flow to the tissue. This is not an allergic reaction and is not irritation — it is a documented, transient pharmacological response that confirms the formula has penetrated the scalp surface and is actively driving circulation to the area. It passes within a few minutes. Clients should be informed in advance so they understand the response as a sign of activity, not a cause for concern.
Inside the formula
Methyl Nicotinate
A niacin derivative that temporarily increases local scalp microvascular circulation — the warming/redness response it produces confirms active penetration and drives the botanical complex into the scalp tissue rather than leaving it on the surface.
Salicylic Acid
Helps lift and dissolve surface accumulation at the scalp — the keratolytic step that clears the follicle opening and prepares the scalp surface for the Methyl Nicotinate to drive actives deeper.
Arnica · Burdock · Rosemary
Arnica montana for scalp comfort, Arctium majus root for congestion and sebum balance, Rosmarinus officinalis for its well-documented role in scalp care — delivered deeper into the tissue by the Methyl Nicotinate microvascular response.
Sulfur + Eucalyptol + Potassium Iodide
Sulfur for sebum-prone scalp balance, eucalyptol for the fresh clarifying sensation and penetration signal, potassium iodide contributing to the formula's overall purifying action.

What is Ampoule KN?
Kapyderm KN is a concentrated single-dose purifying leave-in ampoule from the professional Dermotricology line. Built around arnica, burdock and rosemary with salicylic acid, sulfur, eucalyptol, and Methyl Nicotinate — a microcirculation activator that drives the botanical complex into the scalp tissue. Applied directly to the scalp and left in.
What is the difference between KN and N?
Both are purifying leave-in botanical ampoules built around the same botanical base — arnica, burdock, rosemary, salicylic acid, sulfur, eucalyptol, and potassium iodide. The key difference is that KN contains Methyl Nicotinate — a microcirculation activator that produces a warming or redness response and drives actives deeper into the scalp tissue. N does not contain Methyl Nicotinate. KN also comes in a box of 12 × 8ml ampoules; N in packs of 6 or 20.
What is the warming or redness response?
The warming sensation and temporary redness that follows KN application is produced by Methyl Nicotinate — a niacin derivative that temporarily dilates scalp microvessels. This is a normal, expected, and transient pharmacological response — not an allergic reaction or irritation. It confirms the formula has penetrated the scalp and is increasing local circulation. It passes within a few minutes. Clients should be informed in advance.
How do I use it?
Open the ampoule and apply directly to the area being worked on — alone or layered into the protocol. Massage gently. Do not rinse. The warming response is normal. Discontinue if irritation persists beyond the expected response.
Can it be layered with other ampoules or tonics?
Yes — Ampoule KN can be used as a standalone scalp step or layered into the full protocol sequence. Full layering and sequencing guidance is available through the Professionals Portal for certified Technicians.
How many ampoules come in a box?
A box of 12 single-dose ampoules of 8 ml each. Professional format — suited to in-center and home use between sessions.
