A concentrated purifying lotion for the scalp.
Single-dose professional ampoule — burdock, arnica, rosemary, salicylic acid
Kapyderm N is a concentrated leave-in purifying lotion from the professional Dermotricology line. Applied directly to the scalp and left in — alone or layered into the protocol. Built around burdock, arnica and rosemary with salicylic acid, sulfur, and eucalyptol.
"The purifying ampoule step is what makes everything else in the protocol work — once the scalp is clarified, the tonics and treatments that follow actually reach where they need to go."
Most scalp treatments are applied to a surface that hasn't been properly prepared. The result — product sitting on congestion rather than reaching the scalp tissue beneath it.
Kapyderm N is a concentrated single-dose purifying lotion from Kapyderm's professional Dermotricology line — Técnicas Capilares Profesionales. Applied directly to the scalp and left in, it is the concentrated clarifying step within the Dermotricology protocol. Its botanical blend — Arctium majus (burdock root), Arnica montana, and Rosmarinus officinalis (rosemary) — works alongside salicylic acid for scalp surface clarification, sulfur for scalp balance, potassium iodide, and eucalyptol for a fresh, clarifying sensation that confirms active penetration. It can be used as a standalone scalp step or layered into the full protocol sequence.
Why a purifying step matters in the protocol
A congested scalp — excess sebum, product buildup, flake accumulation at the follicle opening — blocks the tonics and ampoules that follow from reaching the scalp tissue. Ampoule N is formulated as the concentrated clarifying intervention: salicylic acid helps lift surface accumulation, burdock and sulfur address congestion, and the leave-in format means the actives stay in contact with the scalp rather than being rinsed away. What follows in the protocol then reaches a prepared surface — not a blocked one.
Inside the formula
Salicylic Acid
A beta-hydroxy acid that helps lift and dissolve surface accumulation at the scalp — the keratolytic step that prepares the scalp for the rest of the protocol to work effectively.
Sulfur
Long used in scalp care for its balancing and purifying properties on sebum-prone and congested scalps. Works alongside burdock to support the formula's overall clarifying action.
Burdock (Arctium Majus) + Arnica + Rosemary
Arctium majus root for scalp congestion, Arnica montana for scalp comfort, Rosmarinus officinalis for its well-documented role in scalp care — three botanicals with a long history of use in professional hair and scalp formulations.
Eucalyptol + Potassium Iodide
Eucalyptol delivers the fresh, clarifying sensation and warming/tingling signal that confirms the formula is actively penetrating the scalp. Potassium iodide contributes to the formula's purifying action.

What is Ampoule N?
Kapyderm N is a concentrated single-dose purifying leave-in lotion from the professional Dermotricology line. Built around burdock, arnica and rosemary with salicylic acid, sulfur, potassium iodide and eucalyptol — it is the concentrated scalp clarifying step within the Dermotricology protocol, applied directly to the scalp and left in.
How do I use it?
Open the ampoule and apply the lotion evenly to the area being worked on — alone or within the protocol. Massage gently with the fingertips. Do not rinse. A light warming or tingling sensation is normal. Use as advised by your specialist.
Can it be used at home or only in-center?
Both. Kapyderm N is used by certified Technicians as part of in-center protocols and is also available for home use between sessions. Full protocol guidance — attack, normalizing, and maintenance phases — is available through the Professionals Portal.
What is the warming or tingling sensation?
The light warming or tingling sensation comes from the eucalyptol and the formula's active penetration — it is a normal response and confirms the lotion is actively working on the scalp. It is not an allergic or irritation reaction. Discontinue if the sensation persists uncomfortably or if irritation develops.
Can it be layered with other ampoules or tonics?
Yes — Ampoule N is formulated to be used alone as a standalone scalp step or layered into the full protocol sequence alongside other ampoules and tonics. Full layering guidance is available through the Professionals Portal for certified Technicians.
How many ampoules come in a pack?
Ampoule N is available in packs of 6 and packs of 20 single-dose ampoules. The pack of 6 is suited to home use; the pack of 20 to professional center use.
