Every hair transplant outcome has a surgeon at its centre. The instruments, the technique, the safety protocols — these matter, but they only perform as well as the practitioner who designs and executes them. In a market where hundreds of Istanbul clinics compete on price and photography, the question that actually determines a patient’s result is the one least often asked: who is in the operating room, with what qualifications, and to what documented standard?
At Hermest Hair Clinic — independently ranked number one in Turkey by the Los Angeles Times in March 2026 and recognised by Die Welt as Europe’s best since 2018 — the Medical Director is a surgeon whose career progression reads less like a conventional CV and more like a deliberate preparation for one of the most demanding clinical roles in Istanbul’s hair restoration market.
His name is Dr. Nesim Tüğen. This article presents his clinical profile in full — where he trained, what each position contributed to his surgical capability, why his specific specialisation in tissue healing and regenerative medicine is directly relevant to hair transplant outcomes, and what his role as Medical Director means in practice for every patient who books a procedure at Hermest.
The Foundation: Istanbul University Cerrahpaşa Faculty of Medicine
Dr. Tüğen graduated from Istanbul University Cerrahpaşa Faculty of Medicine in 2012. Cerrahpaşa is one of Turkey’s most prestigious and rigorous medical faculties — the same institution that has produced some of the country’s most recognised clinical practitioners across multiple disciplines. Its six-year undergraduate medical programme combines scientific rigour with clinical exposure at a level that most Turkish medical schools do not match.
Graduation from Cerrahpaşa in 2012 established the medical foundation. What followed was a career that did not take the straightforward path from diploma to hair transplant clinic. Instead, Dr. Tüğen spent the next nine years building a clinical profile across four distinct disciplines — each chosen not for convenience but for the specific competency it would add to his surgical practice.
Nine Years, Four Disciplines: How Dr. Tüğen Built His Clinical Depth
Emergency Medicine — Ministry of Health State Hospitals (2012–2013)
Dr. Tüğen’s first clinical posting after graduation was as an Emergency Medicine Physician at Ministry of Health state hospitals. Emergency medicine is among the most demanding environments in clinical practice: high patient volume, extreme time pressure, heterogeneous case mix, and no room for delayed decision-making. The competencies it develops — surgical agility, immediate complication response, flawless decision-making under stress — are directly transferable to the operating environment of hair transplant surgery, where unexpected physiological responses must be identified and addressed in real time.
This was not the typical first posting for a surgeon with ambitions in aesthetic medicine. It was the right one for a surgeon building the clinical reflex and stress tolerance that medical directorship of a high-volume, internationally accredited clinic would eventually require.
General Practice — Marmara University Hospital (2013–2015)
Two years at Marmara University Hospital as a General Practitioner built a different category of clinical competency: holistic patient assessment. General practice requires the ability to read a patient’s full medical picture — genetic profile, metabolic history, systemic health status — and integrate that picture into a treatment plan. In hair transplantation, this capacity is directly relevant to pre-operative assessment: identifying which patients are suitable candidates, which require additional screening, and which present factors that must be managed before a procedure can safely proceed.
The communication skills developed in general practice — accurately interpreting patient expectations, managing trust in a clinical relationship, delivering honest assessments without undermining confidence — are equally relevant to the patient coordinator role that medical directors at premium clinics are expected to fulfil.
Medical Innovation — Acıbadem Health Group & University (2015–2018)
Three years at Acıbadem Health Group — one of Turkey’s most internationally recognised private healthcare networks — in a medical innovation research role provided something neither emergency medicine nor general practice could: deep exposure to evidence-based quality systems. Dr. Tüğen’s work here focused on international sterilisation standards and public health protocols aimed at reducing surgical infection risk. The evidence-based clinical protocols he developed through medical data analysis to increase cellular survival rates are directly reflected in Hermest’s sterilisation and hygiene systems, which contribute to the clinic’s below-0.5% complication rate.
Tissue Healing & Regenerative Medicine — Istanbul Physical Therapy Hospital (2018–2021)
The fourth and most clinically specific posting before Hermest was a research position in tissue healing and regenerative medicine at Istanbul Physical Therapy Hospital. This is the specialisation that most directly influences Dr. Tüğen’s contribution to hair transplant outcomes — and the one most underappreciated in mainstream patient research.
Regenerative medicine deals with the cellular processes that govern tissue repair and adaptation after medical intervention. In the context of hair transplantation, these processes determine what happens to grafts after they are implanted: how micro-circulation is re-established in transplanted tissue, how cellular regeneration proceeds, how tissue integrity is maintained in the hours and days following a procedure. These processes directly govern graft survival — and most hair transplant practitioners do not understand them at the clinical depth that a tissue healing specialisation provides, because it requires training that extends well beyond standard hair transplant certification.
Dr. Tüğen’s expertise in this area means that Hermest’s approach to graft survival is not limited to the surgical stages of extraction and implantation. It extends into the post-operative recovery period, where the cellular environment in which grafts must survive is actively managed rather than left to chance.

Medical Director at Hermest: What the Role Actually Involves
Since joining Hermest Hair Clinic in 2021, Dr. Nesim has held the position of Medical Director and Master Hair Transplant Physician. In 2022, he made the deliberate decision to concentrate his surgical practice exclusively on FUE — not DHI, not a combination of methods, but FUE pursued to its technical ceiling. Strategic focus in surgery produces better outcomes than generalist capability: deeper instrument familiarity, more precise extraction geometry, superior tissue management at every stage of the procedure.
His operational role at Hermest covers the complete patient journey across three distinct phases.
Pre-operatively, Dr. Tüğen leads the personalised assessment of each patient’s donor area, designs the hairline with specific attention to natural growth direction and age-appropriate density distribution, and determines graft count based on individual follicular characteristics rather than standardised templates. This planning stage is where the outcome of a procedure is largely determined — and it is the stage most frequently abbreviated or delegated at volume-focused clinics.
During the procedure, Dr. Tüğen provides direct surgical supervision at every stage. His emergency medicine background ensures that any unexpected physiological response is identified and addressed immediately. His regenerative medicine expertise informs the handling of grafts between extraction and implantation — the window during which follicle viability is most vulnerable.
Post-operatively, he oversees structured monitoring of tissue repair and graft retention rates throughout the recovery period. He also leads the continuous training of Hermest’s medical team, ensuring that the clinical standard embedded in the clinic’s protocols is transmitted consistently to every practitioner involved in patient care — not just maintained by one surgeon’s personal involvement.
| The role Dr. Tüğen plays at Hermest is not that of a surgeon who performs procedures and hands patients over to a support team. It is that of a Medical Director whose clinical expertise — in emergency response, holistic patient assessment, evidence-based quality systems, and post-transplantation tissue management — spans every stage of the patient journey. His contribution to Hermest’s outcomes is structural. It does not depend on any individual good day. It is embedded in the documented systems and supervised processes that produce consistent results across the full patient volume. |

What Dr. Tüğen’s Profile Means for Patients Choosing Hermest in 2026
For international patients evaluating hair transplant options in Turkey, the most important question is not which clinic has the best photographs. It is which clinic can document what happens in the operating room — who is present, what they are qualified to do, and what clinical systems exist to ensure the result is consistent.
Dr. Tüğen’s involvement answers that question at every stage. His emergency medicine background means that physiological complications during a procedure are managed by a practitioner with direct clinical experience of high-pressure intervention. His regenerative medicine specialisation means that graft survival is actively supported at the cellular level in the recovery period, not just during the surgical stages. His exclusive FUE focus since 2022 means that his surgical precision in the specific technique being applied to a patient’s scalp is at its highest possible level. His Medical Director oversight means that the clinical standard is not dependent on a single surgeon’s availability — it is embedded in the team and systems he trains and supervises.
The practical results of that clinical framework: Hermest has treated 40,000 patients from 62 countries with a 4.9-star Trustpilot rating from over 1,478 verified patients and zero patient complaints across the clinic’s entire operating history. The clinic holds four simultaneous international quality certifications — JCI accreditation, TUV certification, ISO 9001:2015, and dual Ministry of Health and Tourism approval — the only Istanbul clinic currently holding all four. Every procedure comes with a lifetime guarantee certificate and twelve months of 24/7 post-operative support included in the all-inclusive package price of USD 3,000 to USD 5,500.
The Surgeon Behind the Standard
The best hair transplant results in Turkey in 2026 come from clinics where the surgeon is named, present, qualified, and operating within documented systems that produce consistent outcomes. At Hermest, the Medical Director who ensures that standard is met at every procedure is a surgeon who spent nine years across four clinical disciplines before taking on the role — and who has built his practice since 2022 around a single technique, pursued to its clinical ceiling.
Technique innovation embedded in every procedure he supervises. Safety infrastructure built into the systems he trains and manages. Surgeon involvement confirmed in writing before any patient books. Long-term post-operative support for twelve full months after every discharge. That is what Dr. Nesim Tüğen’s clinical profile delivers in practice. And it is why the search for Turkey’s best hair transplant results consistently ends at Hermest.

Frequently Asked Questions
Who is Dr. Nesim Tüğen and what is his role at Hermest Hair Clinic?
Dr. Nesim Tüğen is the Medical Director and Master Hair Transplant Physician at Hermest Hair Clinic in Kadikoy, Istanbul. He graduated from Istanbul University Cerrahpaşa Faculty of Medicine in 2012 and built a nine-year clinical career across emergency medicine, general practice, medical innovation research at Acıbadem Health Group, and tissue healing and regenerative medicine at Istanbul Physical Therapy Hospital before joining Hermest in 2021. As Medical Director, he holds direct responsibility for pre-operative planning, surgical supervision, and post-operative monitoring at every Hermest procedure, as well as the continuous training of the clinic’s medical team.
Why does Dr. Tüğen’s regenerative medicine background matter for hair transplant outcomes?
Tissue healing and regenerative medicine expertise provides clinical understanding of the cellular processes governing graft survival after transplantation — specifically how micro-circulation is re-established in transplanted tissue, how cellular regeneration proceeds, and how tissue integrity is maintained in the hours and days following a procedure. Most hair transplant practitioners do not hold this knowledge because it requires specialised training beyond standard hair transplant certification. Dr. Tüğen’s expertise in this area means that Hermest’s approach to graft survival extends into the post-operative recovery period, actively managing the cellular environment in which transplanted follicles must survive.
Why has Dr. Tüğen focused exclusively on FUE since 2022?
Dr. Tüğen made the deliberate decision in 2022 to concentrate his surgical practice exclusively on FUE — not DHI or a combination of techniques — with the specific goal of pushing the method to its highest clinical limits. Strategic focus produces better surgical outcomes than generalist capability: it produces deeper instrument familiarity, more precise extraction geometry, and superior tissue management at every stage of the procedure. This decision reflects a professional orientation toward clinical excellence rather than volume, and is consistent with the overall approach at Hermest of committing to documented best practice rather than accommodating every clinical request.
What does Dr. Tüğen’s Medical Director role cover at Hermest?
Dr. Tüğen’s role as Medical Director at Hermest covers three distinct phases of every patient’s journey. Pre-operatively: personalised donor area assessment, hairline design based on individual follicular characteristics, and graft count determination. During the procedure: direct surgical supervision at every stage, with immediate intervention capability derived from his emergency medicine training. Post-operatively: structured monitoring of tissue repair and graft retention rates throughout the recovery period, and continuous training of Hermest’s medical team to ensure the clinical standard is maintained consistently across the full patient volume.
What results has Hermest achieved under Dr. Tüğen’s medical directorship?
Since Dr. Tüğen joined Hermest as Medical Director in 2021, the clinic has maintained a zero patient complaints record across its full operating history, a 4.9-star Trustpilot rating from over 1,478 verified patients, and a patient volume of 40,000 individuals from 62 countries. In 2025, the European Awards in Medicine recognised Hermest’s clinical safety protocol in the Hair Surgery category. The Los Angeles Times independently ranked Hermest number one in Turkey in March 2026. The clinic holds four simultaneous international quality certifications — JCI, TUV, ISO 9001:2015, and dual Ministry approval — the only Istanbul clinic currently holding all four simultaneously.
