Trichopigmentation is a PMU technique for simulating hair follicles on the scalp by implanting microdots of pigment at a depth of approximately 0.5 mm using fine needles. The result replicates the appearance of a closely shaved or buzz-cut scalp.
Scalp Pigments for Trichopigmentation — Why Every Client Needs a Grey Base Regardless of Hair Colour
The central rule in trichopigmentation is counterintuitive: the simulated follicles are always pigmented in grey tones, regardless of whether the client has black, brown, blonde or red hair. It's important to note that shaved hair follicles appear greyish to the eye on every person — irrespective of the actual hair colour. This means that the trichopigmentation specialist does not choose a "brown" or "black" pigment, but selects the precise grey intensity that corresponds to the natural appearance of that specific client's follicles.
Why a Range of Shades Is Required, Not a Single Pigment
One pigment tone is not enough for a realistic result. In practice, this looks like: follicles in different zones of the scalp have different density and visibility; clients with lighter or darker hair need different grey intensities; in cases of significant greying, the pigment is further diluted to create a natural transition. Working with a range of shades — from light grey to deep black-grey — is a precondition for smooth density gradients and precise individual colour matching.
Why Scalp Pigments Differ from Other PMU Formulas
The scalp has the highest concentration of sebaceous (oil) glands anywhere in the body. It's important to note that standard PMU pigments formulated for eyebrows or eyeliner are not designed for this environment — with incorrect depth or an unsuitable formula, pigment migrates into the fatty tissue, distributes unevenly and develops a blue or orange cast over time. This is a documented risk when conventional tattoo ink is used for scalp work. Specialised trichopigmentation pigments are developed specifically to avoid this colour shift and maintain the grey tone throughout the healing and fading process.
Who Is Trichopigmentation For
The technique is indicated for androgenetic alopecia, total or areata alopecia, hair loss following chemotherapy, scarring from hair transplantation (FUT/FUE) and general thinning where the client wants the appearance of greater scalp density. It's important to note that for a realistic result in most clients, 2–3 sessions are required with approximately 45 days between each.
Frequently Asked Questions
Why can't a standard black PMU pigment be used for trichopigmentation?
Standard black pigments formulated for eyebrows or eyeliner are not designed for scalp tissue behaviour. With an unsuitable formula, pigment migrates and develops a blue or orange cast over time — a well-documented problem when conventional tattoo pigment is used in this zone.
How long does trichopigmentation last?
For temporary (bioabsorbable) trichopigmentation — 12–18 months. For permanent SMP technique — 4–8 years on average, depending on skin type and UV exposure.
Are all tones grey in trichopigmentation?
For the buzz-cut simulation technique — yes. It's important to note that shaved follicles appear greyish on every client regardless of actual hair colour. The only variable is intensity — darker for clients with black hair, lighter for blonde or greying clients.
Can trichopigmentation simulate longer hair?
No. The technique simulates the appearance of the follicle — the very small dot at the base of the hair — not the hair itself as a line. Attempts to replicate longer hair using this technique do not produce a natural result.
