Scalp Micropigmentation in Lisbon

Scalp micropigmentation (SMP, also called tricopigmentation) is an aesthetic technique that deposits tiny dots of pigment into the superficial layer of the scalp, mimicking the look of closely shaved follicles. It does not grow hair and does not stop hair loss: it creates the illusion of density and camouflages thinning areas and scars. At Replace Clinic in Lisbon it is always preceded by a medical assessment with Dr Fátima Garcês, so the cause of the hair loss is diagnosed before any aesthetic procedure.

Clinically reviewed by Dr Fátima Garcês, Clinical Director of Replace Clinic — 20 years dedicated to hair restoration.

Key points

  • Non-surgical aesthetic procedure — no general anaesthetic and no downtime

  • Typically 2 to 4 sessions, 2 to 4 weeks apart, building density in layers

  • Temporary result: it fades over 2 to 5 years and requires maintenance top-ups

What scalp micropigmentation is

Scalp micropigmentation applies pigment into the superficial dermis of the scalp using very fine needles, reproducing the mark a shaved follicle leaves on the skin. At normal viewing distance, thousands of those dots read as short, dense hair.

It is equally important to understand what it does not do: it does not stimulate the follicle, does not recover lost hair and does not replace medical treatment of alopecia. It is visual camouflage, most often used alongside — not instead of — medical treatment or a hair transplant.

It differs from a conventional tattoo in the pigment used, the depth of application (more superficial) and the size of the dot. Because the deposit is shallower, pigments are gradually reabsorbed by the body, which is why the result is temporary.

When it is indicated

Assessment always begins with diagnosing the cause of the hair loss. Only then is it decided whether micropigmentation is the right step, on its own or combined.

  • Male pattern hair loss where the patient prefers to keep the hair very short or shaved
  • Diffuse thinning, in men and women, to reduce the contrast between scalp and hair
  • Camouflage of scalp scars, including the linear FUT/strip scar and FUE extraction dots
  • Limited apparent density when the donor area cannot cover the whole recipient area
  • As a complement after a hair transplant, once healing and growth are established

How a session works

The first session sets the hairline, the density and the pigment tone, matched to your natural hair colour and skin phototype. The approach is deliberately conservative: we start lighter and less dense, then build up in later sessions.

Each session usually lasts 1 to 3 hours depending on the area. Discomfort is mild and topical anaesthetic can be applied. There is no hospital stay and you return to your routine immediately, following the first-days aftercare restrictions.

  • Session 1 — design, tone test and first layer of dots
  • Session 2 (2 to 4 weeks later) — density adjustment and tone correction after healing
  • Sessions 3 and 4, when needed — refinement of transition zones and scars
  • Review 4 to 6 weeks after the final session to confirm the pigment has settled

Aftercare

For the first few days the scalp may look red, and the dots appear darker and larger than the final result — the tone lightens as the skin heals.

  • Do not wash or wet the area for the first 3 to 4 days, as advised by the clinic
  • Avoid heavy sweating, the gym, swimming pools, saunas and steam rooms for around 2 weeks
  • Do not scratch or pick scabs; let them come away naturally
  • Protect the scalp from the sun and use sunscreen long term — sun exposure is the main cause of pigment fading

Risks, limitations and contraindications

Micropigmentation is safe when performed with sterile, single-use material and after proper assessment, but it is not risk-free. Possible issues include allergic reaction to the pigment, local infection, colour change over time (for example, a shift towards grey or blue tones) and unnatural results when the hairline is designed too low or too rigid.

It is not advised, or requires specific prior medical assessment, in cases of keloid tendency, active inflammatory scalp disease (psoriasis, a flare of seborrhoeic dermatitis, folliculitis or infection), known pigment allergy, uncontrolled autoimmune disease, poorly controlled diabetes, anticoagulant therapy and recent isotretinoin use. During pregnancy and breastfeeding the procedure is postponed as a precaution.

In alopecia that is still progressing, the camouflage can fall out of step with ongoing loss. That is why the plan starts with medical control of the alopecia, and the aesthetic component is considered afterwards.

Frequently asked questions

Does scalp micropigmentation grow hair?
No. It is a purely aesthetic technique that creates the illusion of density using pigment placed in the skin. It does not stimulate the follicle or stop hair loss, so it is combined with medical treatment or a hair transplant whenever that is indicated.
How long do the results last?
The pigment sits in a superficial layer and is gradually reabsorbed, so results typically fade over 2 to 5 years. Longevity depends on skin phototype, sun exposure, skin type and the pigment used, and is maintained with periodic top-ups.
How many sessions are needed?
Usually 2 to 4 sessions, 2 to 4 weeks apart. Density is built in layers, which allows tone and intensity to be corrected between sessions and avoids an overly dark result.
Can it camouflage hair transplant scars?
Yes, this is one of the most common indications. It reduces the contrast of linear FUT/strip scars and FUE extraction dots. The scar must be fully stabilised before treatment.
Can I have SMP after a hair transplant?
Yes, but only after complete healing and once growth has settled, which in practice means waiting several months after surgery. The exact timing is decided at a clinical review.
Does it hurt?
Discomfort is mild and comparable to a superficial tattoo. Topical anaesthetic can be applied and sessions are paused whenever needed.
Is it suitable for women?
Yes. In women it is mainly used to reduce contrast in diffusely thinning areas, such as the central parting, rather than to simulate shaved hair. It calls for a lighter tone and lower density.
