Scalp Micropigmentation, or SMP as most people know it, has become one of the most sought-after hair loss solutions in the world. But it didn’t just appear overnight. The journey from its early experimental origins to the highly refined, medically informed treatment we deliver at Foli Sim today is genuinely fascinating, and understanding that history gives you a much clearer picture of just how far this industry has come. Having been in and around the hair loss space for years, through our broader clinic group and our trichology roots, I’ve watched SMP evolve firsthand. It’s been remarkable.
Where Did SMP Actually Begin?
The concept of depositing pigment into the scalp to mimic the appearance of hair follicles isn’t a 21st century invention. Tattooing as a cosmetic tool has existed for centuries, but the specific application to scalp hair loss is generally traced back to the early 2000s. The most widely cited pioneers in the modern SMP field are Ian Watson and Ranbir Rai-Watson, the co-founders of HIS Hair Clinic in the United Kingdom, who are credited with formally developing and naming Scalp Micropigmentation as a distinct cosmetic procedure around 2001 to 2002.
Before that, there were scattered attempts by traditional tattoo artists and cosmetic tattooing practitioners to fill in thinning areas or recreate hairlines. These were largely inconsistent in quality, and many produced poor long-term results. The pigments used were conventional tattoo inks not formulated for scalp skin, the needle configurations weren’t designed for follicle replication, and the technique itself lacked any real standardisation. Results often faded to undesirable blue or green hues over time, or spread beneath the skin to create a blurred, unnatural effect.
The Problem With Early Attempts
This is an important part of the story, and one I think is worth being honest about. Early SMP-style work gave the broader concept a mixed reputation in some circles. Clients who had procedures done with inappropriate inks or by untrained technicians often ended up with results that looked nothing like natural stubble. Instead of crisp, realistic follicle impressions, they were left with faded, blurry marks that were difficult to correct.
The core issues with early attempts included:
- Standard tattoo inks that were not designed for scalp tissue or long-term follicle replication
- Needle gauges that were too large, causing pigment spread and loss of dot definition
- No understanding of scalp skin layers and how pigment settles differently compared to body skin
- Lack of colour theory specific to scalp tones, leading to discolouration over time
- No formalised training pathways or quality benchmarks for practitioners
These early pitfalls are exactly why the development of purpose-built SMP pigments, specialist equipment, and structured training programmes was so critical to the treatment becoming what it is today.
The 2000s: Formalisation and Growing Awareness
Through the mid-2000s, awareness of SMP as a legitimate, standalone procedure began to grow, primarily in the UK and United States. HIS Hair Clinic expanded its operations and continued to refine its technique, building a body of documented results that helped legitimise the treatment in the eyes of both the public and the wider hair loss industry.
Around the same time, training bodies and courses began to emerge, though standards varied enormously. The more credible training programmes drew on dermatological knowledge, understanding of scalp biology, and the specific physics of how fine-gauge needles interact with skin at different depths. This period also saw the development of pigments specifically formulated for SMP. These were carbon-based, organically sourced inks designed to hold their tone over time without the colour drift that plagued earlier work.
By the late 2000s, a small but growing community of highly skilled SMP practitioners existed globally, and results were becoming consistently impressive in the hands of the right artists. Word of mouth spread quickly among men experiencing hair loss, partly because the results, when done well, were genuinely difficult to distinguish from a freshly shaved head of hair.
The 2010s: Global Expansion and Industry Maturation
The 2010s were arguably the decade that transformed SMP from a niche procedure into a mainstream hair loss solution. Several things happened simultaneously that drove this growth.
Social media, particularly Instagram and YouTube, allowed before and after results to circulate at scale. Clients who were happy with their outcomes started sharing photos and videos, and the visual nature of SMP made it exceptionally well-suited to this kind of organic, evidence-based marketing. People could see real results from real clients, without relying purely on clinic-produced advertising.
Training also became more formalised and internationally recognised. Respected bodies like Goldeneye in Europe developed structured Diploma programmes in SMP. Foli Sim’s own Kate Dawes completed her Diploma of SMP with Goldeneye in 2011, then went on to complete her Masters in SMP with the highly regarded Matt Iulo of Scalp Micro USA in 2017. That level of internationally recognised training matters enormously, and it reflects how seriously the better practitioners in this field take their craft.
Equipment and pigment science continued to advance as well. Digital machines with precise depth and speed control replaced cruder hand-held devices for many practitioners. Needle cartridges designed specifically for SMP work became widely available. Pigment formulations became more sophisticated, with better colour stability and more natural interaction with varying scalp tones across different skin types and ethnicities.
SMP Meets the Medical World
One of the more significant shifts in the evolution of SMP was its growing recognition within medical and trichological communities. Hair restoration surgeons began recommending SMP as a complement to Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE) procedures, particularly for camouflaging linear scarring left by FUT strip surgery, or for adding density to areas where transplanted hair didn’t achieve full coverage.
This is something we see regularly at Foli Sim. Clients come to us after hair transplant procedures looking to address scarring or fill in areas where the transplant result fell short of expectations. SMP in these cases isn’t a replacement for the transplant. It’s a complementary solution that can dramatically improve the overall aesthetic outcome.
The involvement of trichologists, specialists in hair and scalp health, also added a layer of clinical credibility to SMP as a discipline. Understanding the underlying causes of a client’s hair loss, whether it’s androgenetic alopecia, alopecia areata, scarring alopecia, or something else entirely, informs how SMP should be approached and what outcome is realistic. Foli Sim grew out of our Perth-based trichology clinic, Medical Hair Restoration Australia, which identifies and treats the causes of male and female hair loss. That clinical background informs how we approach every client consultation and treatment plan.
How the Procedure Itself Has Evolved
The physical technique of applying SMP has come a very long way from its origins. Modern SMP, as performed by qualified practitioners today, is a highly controlled, multi-session process. Here is how the procedure has evolved in practice:
- Session structure: Quality SMP is always delivered across multiple sessions. At Foli Sim, even mild hair loss requires 3 sessions, spaced 10 to 14 days apart. Each session allows pigment to settle and the scalp to heal before the next layer of detail is added. Rushing the process produces inferior results.
- Pigment depth control: Modern practitioners understand that scalp skin is thinner and more variable than body skin. Depositing pigment at the correct depth, not too shallow and not too deep, is a skill developed through substantial training and experience.
- Dot size and density: The replication of individual hair follicles requires extremely fine, precise dots. The size, spacing, and density of these dots must vary across the scalp to reflect natural follicle distribution patterns. Too uniform, and it looks artificial. A skilled practitioner makes deliberate, individualised decisions about every area of the scalp.
- Colour matching: Pigment selection now accounts for the client’s natural hair colour, skin undertone, and how pigment is expected to evolve over time. Colour theory and pigment science are fundamental to a quality outcome.
- Hairline design: Hairline placement is one of the most critical elements of SMP. It must be appropriate for the client’s age, face shape, and bone structure. A hairline that looks great at 35 needs to look appropriate at 55. Experienced practitioners think about this carefully.
SMP in Australia: Where We’ve Come From
Australia was a relatively early adopter of SMP compared to many markets, though the level of quality and professionalisation has varied widely across the country. In the early days of SMP reaching Australian shores, there were, as in every market, both excellent practitioners and some who weren’t up to standard. That’s changed considerably, and the Australian market now has some genuinely world-class SMP practitioners.
At Foli Sim, we’ve been part of that evolution. We operate Australian Health Department Certified studios in Perth, Melbourne, and Sydney, using only medical-grade equipment and purpose-formulated SMP pigments. Every procedure is performed in sterile clinic environments with single-use needles. The standards we hold ourselves to now would have been considered exceptional a decade ago. Today, we consider them the baseline.
Where SMP Is Headed: The Future of the Treatment
The evolution of SMP isn’t finished. Several trends are shaping where the treatment is heading in the coming years.
Better pigment formulations continue to be developed, with even greater colour stability and more predictable long-term behaviour across different skin types. This is particularly important for clients with darker or more olive complexions, where pigment interaction can be more complex.
Improved documentation and analysis tools, including high-resolution scalp imaging, are helping practitioners plan treatments with greater precision before a single needle touches the scalp. Understanding the existing follicle distribution and scalp characteristics in detail allows for more targeted, natural-looking outcomes.
A broadening client base is also shaping the future of SMP. What was once sought almost exclusively by men with advanced hair loss is now being chosen by women managing thinning hair, younger clients in the earlier stages of hair loss, and people looking to address scalp scarring from surgery or injury. As awareness grows and results speak for themselves, the treatment is reaching people who might never have considered it an option before.
Regulatory maturation in Australia and internationally is also improving. As governments and health bodies develop clearer frameworks around cosmetic tattooing and SMP specifically, the industry’s baseline standards will continue to rise. That’s good news for anyone considering the treatment.
What This History Means for You
If you’re considering SMP, understanding this history is genuinely useful. It explains why choosing a properly trained, experienced practitioner matters so much. The gap between excellent SMP and poor SMP is significant, and the consequences of a substandard result are not trivial. It also puts into context why the procedure requires multiple sessions, why specific pigments are used, and why techniques that might have seemed cutting-edge a decade ago are now considered standard practice.
At Foli Sim, everything we do reflects the lessons this industry has learned over more than two decades. Our practitioners are trained to an internationally recognised standard, our studios are certified and medically compliant, and our approach to each client is built around producing a result that looks genuinely natural. Not just on the day it’s completed, but for years to come.

Frequently Asked Questions
Q1: When was Scalp Micropigmentation first developed as a formal treatment?
Scalp Micropigmentation as a formally named and structured procedure is generally credited to Ian Watson and Ranbir Rai-Watson of HIS Hair Clinic in the United Kingdom, who developed the technique around 2001 to 2002. Prior to this, some practitioners had experimented with depositing pigment into the scalp to simulate hair follicles, but there was no standardised method, no purpose-built pigments, and no formal training pathways. The work of HIS Hair Clinic in the early 2000s was pivotal in establishing SMP as a legitimate, replicable cosmetic procedure with consistent, documentable outcomes. Since then, the treatment has evolved substantially in terms of technique, pigment science, equipment, and global practitioner standards.
Q2: Why did early SMP attempts often produce poor results?
Early SMP-style procedures suffered from several fundamental problems. Standard tattoo inks, not designed for scalp skin or long-term follicle simulation, were commonly used, and these often faded to blue or green tones over time. Needle gauges were too large for the fine detail required, causing pigment to spread beneath the skin and lose the crisp dot definition needed to convincingly replicate hair follicles. There was also little understanding of scalp skin biology, including how much thinner scalp skin is compared to body skin, and how depth of pigment deposition affects long-term outcomes. The absence of formal training standards meant results varied wildly between practitioners. Modern SMP uses purpose-formulated pigments, specialist equipment, and techniques developed and refined over more than two decades of clinical experience.
Q3: How has SMP technique improved over the years?
The improvements in SMP technique over the past two decades have been considerable. Pigments are now specifically formulated for scalp use, with better colour stability and more predictable long-term behaviour across different skin tones. Digital machines with precise depth and speed control have replaced cruder equipment, allowing for more consistent and controllable application. Needle configurations are designed specifically for creating fine, realistic follicle impressions rather than the solid lines used in conventional tattooing. Practitioners now have structured, internationally recognised training programmes to complete, including Diploma and Masters-level qualifications. The multi-session approach to SMP has become standard practice, allowing pigment to settle and be refined progressively rather than attempting to achieve a finished result in a single appointment.
Q4: How many sessions does SMP require, and why?
At Foli Sim, all SMP treatments require 3 sessions, regardless of the degree of hair loss. This applies even for clients with mild thinning. The scalp skin needs time to heal and for pigment to fully settle between sessions. Each appointment builds on the previous one. The first session establishes the foundational layer and overall treatment plan, the second adds density and refines coverage, and the third session addresses remaining detail, definition, and any areas that need adjustment. Sessions are spaced 10 to 14 days apart to allow adequate healing. Attempting to complete SMP in fewer sessions compromises the final result. The multi-session approach has become standard practice precisely because it consistently produces better, more natural-looking outcomes.
Q5: How does SMP differ from a regular tattoo?
Although SMP uses a needle and pigment, similar to tattooing, the two are quite different in practice. SMP uses pigments specifically formulated for scalp skin, which behave differently from standard tattoo inks and are designed to maintain a natural, hair-follicle appearance over time rather than the bold, saturated colours of decorative tattoos. The needle configurations used in SMP are much finer, designed to create tiny, precise dots that replicate individual follicle openings rather than solid lines or shading. Scalp skin is also considerably thinner and more sensitive than body skin, so the depth of pigment deposition must be carefully controlled. The overall technique requires a specific skillset distinct from conventional tattooing, which is why practitioners undergo dedicated SMP training rather than relying on general tattooing experience.
Q6: Is SMP recognised by hair loss and medical professionals?
Yes. SMP has gained increasing recognition within both the hair loss and broader medical communities over the past decade. Hair restoration surgeons regularly recommend SMP as a complement to surgical procedures like FUT and FUE hair transplants, particularly for camouflaging scarring or adding density to areas where transplant coverage is incomplete. Trichologists, specialists in hair and scalp health, also increasingly work alongside SMP practitioners to ensure clients receive appropriate advice about their hair loss situation before committing to treatment. Foli Sim’s own background is in trichology through our associated clinic Medical Hair Restoration Australia, which gives us a clinical perspective that informs how we consult with and treat every client. SMP is now widely accepted as a legitimate, evidence-based cosmetic procedure for hair loss across a range of causes and presentations.
Q7: How much does SMP cost in Australia?
SMP pricing in Australia varies based on the degree of hair loss, the size of the area being treated, and the complexity of the individual case. At Foli Sim, pricing as a general guide starts from approximately $500 to $1,200 for mild hair loss, $1,500 to $2,500 for medium hair loss, and $2,200 to $3,200 for advanced hair loss. Because every client’s situation is different, we don’t apply a fixed price list. We assess each case individually and provide a personalised quote during consultation. We also offer interest-free payment plans through our finance partner ZipMoney, making the treatment more accessible. Free consultations are available in person at our Perth, Melbourne, and Sydney studios, as well as by phone or video. Full pricing details are available on our SMP costs page.
