How many grafts do you need? Follicular units, donor area and graft quality in a hair transplant
In short: In a hair transplant, the graft is the unit of work, of planning and usually of pricing. A graft is a follicular unit, a natural group of one to four hairs, so the same number of grafts can carry very different amounts of hair. Your donor area at the back and sides of the scalp is a finite bank: what is taken today cannot be taken again, and over-harvesting leaves a thin, patchy donor zone that cannot be repaired. A good plan therefore asks three questions: how many grafts are needed now, how many your donor area can safely give over a lifetime, and how many should be kept in reserve if hair loss progresses. This guide explains follicular units, donor density, graft quality and how to read a graft count in a quote from Switzerland.
This article is general information. It does not replace a consultation or medical advice from a qualified doctor.
This guide is about grafts and the donor area. For the techniques themselves, see our guide to FUE, DHI and graft numbers for men. For diagnosis and preparation, read before a hair transplant, and for what to expect afterwards, our guide to hair transplant results.

What exactly is a graft?
A graft is a follicular unit: a small group of hair follicles that grow together from the scalp as a natural bundle. Modern hair transplantation moves these units, not individual hairs, from the donor area to the thinning area.
How many hairs are in a follicular unit?
Usually one to four hairs, sometimes more. Medespoir’s page on the number of grafts explains that counting in grafts therefore means counting units, not individual hairs. A donor area rich in two- and three-hair units supplies more hair for the same number of grafts.
How dense is a typical donor area?
A classic study published in Dermatologic Surgery in 1999 counted follicular units in the occipital (back of the head) donor area of 50 patients using digital photography. It found between 65 and 85 follicular units per square centimetre and between 124 and 200 hairs per square centimetre, with units spaced about 1.0 to 1.4 mm apart. The proportion of one-, two- and three-hair units changed with each patient’s hair density. Later studies in other populations found broadly similar values: a 2017 study in Asian men reported averages of about 61 to 64 units per square centimetre, and a 2019 study of 580 Indian men found a mean of about 78 units per square centimetre on the scalp and about 50 in the beard.
Why do surgeons talk about « units » rather than plugs?
Because older techniques moved larger plugs containing many hairs, which created the unnatural « doll’s hair » look. Moving individual follicular units, and placing single-hair units at the hairline, is what allows a modern transplant to look natural. The graft is therefore both a unit of measurement and a guarantee of a natural design.
Grafts or hairs: why the difference matters
The number of grafts tells you how many units were moved; the number of hairs tells you how much coverage you will get. Two patients with the same graft count can end up with very different amounts of hair.
What is the hair-to-graft ratio?
It is the average number of hairs per graft. A 2020 study of follicular unit extraction (FUE) in ten patients found a ratio of about 1.6 hairs per unit in the central back of the scalp and about 1.85 on the sides. In other words, ten thousand hairs might require around five to six thousand grafts, depending on where they come from and on your natural hair grouping.
Why does hair thickness matter?
Thick hair covers more scalp than fine hair at the same density. Medespoir’s graft page notes that a patient with thick hair may achieve satisfying coverage with a more moderate estimate than a patient with fine hair aiming for the same look. Contrast also counts: dark hair on pale skin makes thinning more visible, while hair and skin of similar colour hide it better. Curly or afro-textured hair covers more surface per hair, as our guide to afro, curly and grey hair explains.
Should a quote state hairs as well as grafts?
Ideally, yes, or at least the expected distribution of one-, two- and three-hair units. Asking this question shows the clinic that you understand the difference and helps you compare proposals. A very high graft number made of mostly single-hair units may give less coverage than a lower number of denser units.
How many grafts do you need?
The number of grafts you need depends on the area to cover, the density you want, your remaining hair, your hair characteristics and, above all, what your donor area can supply. No serious clinic can give a reliable number without examining you.
What do specialists typically transplant?
The International Society of Hair Restoration Surgery (ISHRS) publishes a practice census of its members. In its 2025 census, covering activity in 2024, members reported an average of about 2,262 grafts per typical FUE case and about 2,100 per strip (FUT) case. Most FUE cases fell between 1,000 and 3,999 grafts. Members also reported that patients needed an average of 1.5 procedures to achieve the desired result, with a median of one. These figures describe averages across very different patients; your own number may be lower or much higher.
How does the Norwood stage change the estimate?
The more advanced the hair loss on the Norwood-Hamilton scale, the larger the area to cover and the more grafts are needed. But the donor area does not grow with the bald area. Medespoir’s graft page summarises the dilemma: at advanced stages, it is often necessary to prioritise and sometimes give up covering every zone at maximum density, in favour of a harmonious and durable result.
How are grafts distributed across the scalp?
| Zone | Priority | Type of grafts usually placed | Comment |
|---|---|---|---|
| Hairline | Usually highest | Single-hair units for a soft, irregular edge | Frames the face; small number of grafts with a large visual effect |
| Temples (temporal recessions) | High | Fine units, angled very flat | Over-lowering them can look unnatural with age |
| Front and mid-scalp | High | Two- and three-hair units behind the hairline | Creates volume and the impression of density |
| Crown (vertex) | Variable | Mixed units following the natural swirl | Can absorb many grafts; often treated later or partly |
Why is the crown often treated last?
Because it can consume a large number of grafts for a modest visual effect, and because baldness in the crown may continue to expand. Medespoir’s graft page notes that this sometimes leads to treating the crown in a second stage. Many people find that a well-designed front, which frames the face, matters more to their appearance than full coverage at the back.
The donor area: a limited bank
Your donor area, at the back and sides of the head, contains hair that is genetically resistant to pattern baldness. It is the real ceiling of any hair transplant: you cannot transplant more grafts than it can safely supply.
What is the « safe donor zone »?
It is the part of the donor area where hair is expected to remain for life. Modern transplantation relies on the principle of « donor dominance »: transplanted hair keeps the resistance of the area it came from. If grafts are taken from outside the safe zone, they may come from hair that will itself be lost later, and the transplanted hair would then fall out too.
Can the safe zone be predicted in young patients?
Not perfectly. A 2024 study from New Delhi proposed estimating the permanent zone from each patient’s own measurements: it found that the permanent zone corresponded to roughly 0.43 to 0.53 times the distance from the top of the head (vertex) to the occipital bone. The authors suggested this method for patients at early stages of hair loss, when the final pattern is not yet visible. It illustrates an important point: in a young man with early hair loss, the surgeon must plan for a donor area that may shrink at its edges over the coming decades.
How many grafts can a donor area give?
It varies widely. The 2019 study of 580 Indian men, which assumed that about a quarter of the units in each zone could be extracted, estimated that the total available grew from roughly 2,000 to more than 3,600 units depending on whether a limited, standard or extended donor zone was used, plus about 800 from the beard. These figures are specific to that population and method, but they show why a surgeon must measure your density before promising a number. Medespoir’s graft page puts it simply: an estimate that ignores the donor area has no value.
How is donor density measured?
By examining the scalp closely, often with a magnifying device or a camera (trichoscopy) that counts hairs and units in a defined area. The surgeon also assesses hair thickness, colour, the laxity of the scalp (important for strip surgery) and any thinning in the donor zone itself. Thinning in the donor area can signal diffuse hair loss, which makes a transplant riskier and sometimes inadvisable.
Over-harvesting: the damage that cannot be undone
Over-harvesting means extracting too many grafts from the donor area, or extracting them too close together. It is one of the most serious long-term problems in hair transplantation because the donor area does not regenerate.
What does an over-harvested donor area look like?
It looks thin, patchy or « moth-eaten », with visible white dots where grafts were removed. The damage is most visible when hair is cut short. Medespoir’s graft page warns that taking too many grafts, or concentrating extraction, leaves visible traces, especially with short hair, and that a surgeon must spread extraction and keep future sessions in mind: the donor capital is managed over time, not only for the current session.
Why are very large single sessions a concern?
Extracting a very large number of grafts in one day can push extraction beyond what the donor area can sustain, and it also tires the team. A 2020 study of 25 patients undergoing FUE sessions of more than 2,000 grafts found that the damage to follicles during extraction (transection) increased markedly between the beginning and the end of the procedure, and that the increase was greater in larger sessions. This does not mean that large sessions are always wrong, but they require an experienced team and an adequate donor area.
Can an over-harvested donor area be repaired?
Only partly. Options include transplanting beard or body hair into the donor area to camouflage gaps, scalp micropigmentation to reduce the contrast of white dots, and keeping hair slightly longer. None restores the original density. Prevention is the only real solution.
Graft quality: why a graft is not always a graft
Two clinics can both announce the same graft count and deliver very different results, because grafts can be damaged during extraction, preparation and implantation. Damaged grafts may not grow, or may grow thin hairs.
What is transection?
Transection means cutting a follicle during extraction, so that the graft contains a damaged or partial hair root. In FUE, the punch works partly blind: the surgeon cannot see the follicle below the skin, so the angle and depth must be judged precisely. A 2020 study found that transection was lower in the central back of the scalp than on the sides, which is one reason why extraction is often concentrated in the safest and most productive zones.
What is « hidden transection »?
It is damage to follicles that remain in the scalp after a neighbouring graft is extracted. A 2016 study in Dermatologic Surgery found that two surgeons with similar visible transection rates had very different hidden transection: the beginner’s rate was about four times the expert’s. In other words, a graft count does not reveal how much donor hair was destroyed to obtain it.
Does punch size matter?
Yes. Smaller punches leave smaller marks but can damage more follicles if the angle is wrong; larger punches leave larger scars. In the ISHRS 2025 census, most member surgeons reported using punches between 0.81 and 1.00 mm, and most used motorised hand-held devices for FUE. Ask which size will be used for your hair type: curly hair often needs special care because the root curves beneath the skin.
Who extracts and implants the grafts?
This is one of the most important questions. A 2024 review by a Greek hair surgeon warned that FUE is often marketed as « minimally invasive » or « not even surgery », which has encouraged low-cost clinics where unqualified technicians perform the extraction. The author stressed that FUE is a blind technique that takes years to master and can cause permanent damage if done badly. The ISHRS position statement on qualifications for scalp surgery says that any skin incision to remove or receive tissue, including FUE graft harvesting and recipient site creation, is surgery and must be performed by a properly trained and licensed physician, as should diagnosis, planning and hairline design.
What helps grafts survive?
Most grafts grow when they are extracted cleanly, kept in good conditions and implanted quickly and gently. A 2020 meta-analysis in Aesthetic Plastic Surgery found high pooled graft survival in patients with non-scarring hair loss, with lower and more variable values in scarring alopecia. Survival in your case depends largely on how your grafts are handled.
Which factors matter most?
A 2010 review of factors affecting graft growth concluded that surgeons should focus first on the fundamentals: hydration, temperature, time out of the body and gentle handling. Advanced storage solutions and additives may help, but only once these basics are respected.
- Hydration: grafts must never dry out, even for a short time.
- Temperature: grafts are usually kept cool in a storage solution between extraction and implantation.
- Time out of body: the shorter, the better; a well-organised team implants grafts without long delays.
- Gentle handling: squeezing or crushing the bulb with forceps can kill the follicle.
- Implantation density and depth: placing grafts too close together or too deep can reduce growth.
Does your health affect graft survival?
Yes. Smoking reduces blood flow to the scalp, and uncontrolled medical conditions may slow healing. Our guide to hair transplant aftercare explains how to protect grafts in the first days, when they are most fragile.
When can you judge how many grafts grew?
Only after about 12 months, sometimes longer for the crown. Transplanted hairs usually shed in the first weeks and regrow from the third or fourth month. Counting hairs in a marked area on standardised photos, before surgery and at 12 months, is the most objective way to assess growth.
FUE, FUT and the lifetime donor supply
The two main extraction techniques use the donor area differently. FUE removes units one by one with a small punch; FUT (strip surgery) removes a strip of scalp from which units are dissected under a microscope.
Which technique is most common?
FUE. In the ISHRS 2025 census, transplantation with FUE harvesting was by far the most common method for both men and women, followed by strip harvesting and combined strip and FUE. FUE leaves small, scattered marks instead of a linear scar, which suits people who wear their hair short.
Does the technique change how many grafts you can get in a lifetime?
It can. FUE spreads extraction across the donor area, so the remaining density decreases evenly; there is a limit beyond which thinning becomes visible. FUT takes grafts from a strip in the densest zone, leaving the surrounding density intact but creating a linear scar. Some surgeons combine the two methods over a patient’s lifetime to maximise the total number of grafts available, for example strip surgery first, then FUE in the surrounding area later. A 2024 article in Aesthetic Plastic Surgery described a sequential strip and FUE method in the same operation, and warned that very large « mega » and « giga » sessions in young patients risk depleting the donor area.
What about DHI and sapphire blades?
DHI (direct hair implantation) and sapphire blades concern how grafts are implanted or how recipient incisions are made, not how they are extracted. They do not change the donor supply. They may influence handling and the precision of angles, but the quality of the team matters more than the name of the technique.
| Aspect | FUE | FUT (strip) |
|---|---|---|
| Extraction | Individual units with a punch | Strip of scalp, then microscopic dissection |
| Donor scar | Small scattered dots | One linear scar |
| Effect on donor density | Even reduction over the whole zone | Surrounding density preserved |
| Short hairstyles | Usually easier to wear | Scar may show with very short hair |
| Main risk for the donor area | Over-harvesting and hidden transection | Wide or stretched scar |
Beard and body hair as extra donors
When the scalp donor area is limited, beard and sometimes chest hair can be used as additional sources. They are useful but have limits.
Do beard and body hairs look like scalp hair?
Not entirely. A 2013 study of 35 men who received beard and body hair transplanted to the scalp found that, over follow-up of six months to two years, the hairs kept the colour, curl and thickness they had in their original location. Beard hair is often thicker, which can add coverage in the crown, while chest hair is usually finer and grows to a shorter length. These differences must be planned carefully.
How often is non-scalp hair used?
Rarely. In the ISHRS 2025 census, the scalp remained by far the most common donor site, with beard far behind and chest and other body areas rarely used. Non-scalp donors are generally a complement for advanced hair loss or repairs, not a first choice.
Can a beard be used and still look full?
Extraction under the jawline, where the beard is hidden, is usually preferred. Taking grafts from the visible beard can leave it patchy. If you also want a beard transplant one day, discuss both projects together, as they draw on related resources. Our guide to beard and eyebrow transplants covers this.
Keeping grafts for the future
Pattern hair loss usually continues after a transplant. The grafts you keep in reserve today may be essential to maintain a natural look in ten or twenty years.
Why does age matter so much?
Because the final extent of hair loss is not known in young patients. A man in his twenties with an early receding hairline may, by his fifties, have lost the top of his head. If most of his donor area has been used to create a low, dense hairline, there may be too few grafts left to cover what is lost later, leaving an isolated « island » of transplanted hair. This is why experienced surgeons are cautious with young patients, as explained in our guide to assessment before surgery.
How does medical treatment protect the donor investment?
Transplanted hair resists pattern hair loss, but the hair around it does not. The European S3 guideline on androgenetic alopecia (2018) recommends finasteride and minoxidil as the main medical treatments for men, and minoxidil for women. By slowing further loss of native hair, these treatments reduce the number of grafts needed in the future and help keep the result harmonious. They have side effects and require a prescription and medical follow-up; discuss them with a dermatologist.
What does a « lifetime plan » look like?
| Question | Short-term focus | Long-term focus |
|---|---|---|
| Hairline position | As low as possible | A mature position that suits you at 50 and 70 |
| Graft use | Maximum number now | Enough now, with a reserve for later |
| Crown | Covered in the first session | Treated if stable, often later |
| Native hair | Ignored | Protected with medical treatment if appropriate |
| Donor area | Harvested heavily | Harvested evenly within the safe zone |
When is a second session reasonable?
Usually after the first result has matured, around 12 months, once the surgeon can see what grew and how your native hair has evolved. The second session uses grafts from the same finite bank, which is why the first plan should already consider it. In the ISHRS census, two-thirds of member surgeons reported that their patients needed, on average, one procedure to reach the desired result; others needed more.
Special situations: women, repairs and counting on the day
The general rules on grafts and donor areas apply to everyone, but some situations change the calculation.
Are graft numbers different for women?
Often, yes. Hair loss in women usually follows a diffuse pattern, with thinning over the top of the head rather than a receding hairline, and it is described by other classifications than the Norwood scale. Medespoir’s graft page notes that the approach is the same in substance: evaluate the surface, the starting density and the reserve, then estimate a coherent number of grafts confirmed by the doctor. The difficulty is that diffuse thinning can also affect the donor area. If the back of the head is thinning too, the hair taken there may not be permanent, and a transplant may be inadvisable. A careful medical work-up, including blood tests when appropriate, comes first. Our guide to female hair loss covers the causes and treatments.
What changes when a previous transplant needs repair?
Repairs are more complex because the donor area has already been used, sometimes heavily. The surgeon must first assess what remains, then decide whether to remove or redistribute badly placed grafts, soften an unnatural hairline or add density. With less donor hair available, priorities matter even more. Medespoir has a page on correcting a failed hair transplant, and the ISHRS organises an annual awareness day on repair surgery.
Can grafts be placed into scars?
Yes, in many cases, including old strip scars, accident scars and some surgical scars. Scar tissue has a poorer blood supply than normal skin, so growth can be less predictable, and the 2020 meta-analysis found more variable graft survival in scarring alopecia than in pattern hair loss. A test session with a limited number of grafts is sometimes proposed before a larger one.
How are grafts counted on the day of surgery?
In a well-organised clinic, grafts are sorted and counted as they are extracted, often by number of hairs, and kept in labelled containers. The total extracted and the total implanted are then recorded in the operation report. Asking how counting is done, and whether you will receive the figures, is a simple way to check the clinic’s rigour. A difference between the number announced in the quote and the number actually harvested is not necessarily a problem, as the doctor may adapt to what your donor area allows on the day, but it should be explained to you.
Why might the doctor harvest fewer grafts than planned?
Because the donor area may prove less dense, the hair more fragile or the follicles more curved than expected once examined closely under magnification. A responsible doctor will stop at a safe limit rather than force the planned number. This is precisely the situation in which knowing in advance what the quote says about fewer grafts than expected becomes useful.
Graft counts in offers: warning signs
Because grafts are easy to count and advertise, they are also easy to misuse in marketing. Some warning signs should make you cautious.
Which promises should worry you?
- A precise graft count given without photos or examination. Medespoir’s graft page insists that no number should be promised blindly: a serious estimate starts from photographs, then a direct examination, and is expressed as an order of magnitude to be confirmed.
- « Unlimited grafts » or « maximum grafts » packages. They encourage over-harvesting and ignore your donor capacity.
- Very large single sessions presented as standard. They may be possible for some patients, but not for everyone.
- No mention of who performs each step. Ask whether a doctor makes the incisions and supervises extraction.
- No discussion of future hair loss or medical treatment. A plan that only looks at today is incomplete.
- Pressure to decide quickly, or a price that changes once you arrive.
What do experts say about the hair transplant tourism market?
A 2025 review by a team at the Mayo Clinic, published in Aesthetic Plastic Surgery, examined the international hair transplant industry with Istanbul as a case study. It acknowledged that some centres offer effective treatment with high graft survival, but documented aggressive digital marketing, an expanded role for unsupervised technicians and « bait and switch » practices in parts of the market. It advised patients to recognise that large price differences may reflect differences in resources, surgeon experience and safety protocols. The ISHRS also runs a consumer campaign against « black market » clinics, and its 2025 census lists repairs of previous black-market transplants among the procedures performed on men.
How can you protect yourself?
Ask for the name and qualifications of the doctor, a written plan with the estimated number of grafts and the zones to be treated, and a clear statement of what happens if fewer grafts can be harvested than expected. Keep your operation report with the actual number of grafts extracted and implanted. Our guide to hair transplants in 2026 lists further questions.
Questions to ask about grafts
These questions help you compare clinics on what really matters: the quality and sustainability of the plan.
- What is my donor density, and how did you measure it?
- How many grafts do you estimate my donor area can supply over my lifetime?
- How many grafts do you plan now, and how many will remain in reserve?
- How will the grafts be distributed between the hairline, mid-scalp and crown?
- What proportion of one-, two- and three-hair grafts do you expect?
- Which punch size and extraction method will you use for my hair type?
- Who will extract, who will make the recipient incisions and who will implant?
- How are grafts stored, and how long do they stay out of the body?
- What happens if my donor area yields fewer grafts than planned?
- Will the operation report state the exact number of grafts?

How grafts relate to the price
Grafts are the main driver of the work involved in a hair transplant, so they often influence the price. But the cheapest price per graft is not necessarily the best value if the grafts are poorly harvested or your donor area is damaged.
How are hair transplants usually priced?
Clinics use different models: a price per graft, a price per session up to a certain number of grafts, or an all-inclusive package covering the operation, accommodation and transfers. When comparing offers, look at what is included and at the number of grafts you actually need, not at the number advertised.
Why can « more grafts for the same price » be a poor deal?
Because grafts you do not need are taken from your donor bank for good. Extra grafts placed in an area that did not need them cannot be used later where they would have mattered. And a large count obtained with high transection may produce fewer hairs than a smaller count harvested carefully.
What does Medespoir offer?
Medespoir offers hair transplants in its clinics in Tunisia and in Istanbul. Both destinations are significantly cheaper than Switzerland; the exact price is given in a free, personalised quote within 48 hours, and the quote can compare the two destinations. In Tunisia, consultations and medical documents are in French. Medespoir’s graft page describes its role as coordinator: collecting photos and medical history, providing an initial orientation, organising the stay, and relaying follow-up in Switzerland, while the estimate and confirmation of the number of follicular units are the responsibility of the doctor who examines your scalp.
What does the Tunisian package include?
It includes the pre-operative consultation, tests, the procedure, the full team, the operating room, care, the final check and discharge, the operation report, a hotel with full board for you and one accompanying person, all transfers, and remote follow-up after your return to Switzerland. Flights, personal expenses, extensions for convenience, care received in Switzerland, travel insurance (recommended) and bank charges remain at your expense.
Planning from Switzerland
For people living in Switzerland, a transplant for pattern hair loss is a self-funded cosmetic treatment. Planning therefore involves the medical assessment, the trip and follow-up at home.
Does basic health insurance pay for a hair transplant?
No, not for pattern hair loss treated for cosmetic reasons. Basic health insurance (KVG/LAMal) may cover the diagnosis of hair loss by a doctor, for example to rule out a thyroid problem or iron deficiency, under the usual conditions of your policy and deductible.
What documents should you prepare?
- Recent photos taken in good light, including the donor area with hair slightly short.
- A list of medicines and any previous treatment for hair loss.
- Results of any blood tests done by your doctor or dermatologist.
- Details of any previous transplant, ideally with the old operation report.
What should you bring back?
The operation report stating the number of grafts extracted and implanted, the zones treated and the technique used. It is essential for planning any future session, for a dermatologist in Switzerland and for objective follow-up of your result. Combined with standardised photos at 6, 9, 12 and 18 months, it allows you to judge how well your grafts grew.
Should you see a dermatologist in Switzerland?
It is a good idea, especially if you start or continue medical treatment, which requires prescriptions and monitoring. A dermatologist can also follow the evolution of your native hair and your donor area over the years.
Your checklist
- Ask for a donor area assessment before accepting any graft number.
- Ask how many grafts will remain in reserve for the future.
- Prefer a mature, durable hairline over an aggressive one.
- Check who performs each surgical step.
- Ask about graft handling, storage and time out of the body.
- Discuss medical treatment to protect your native hair.
- Get the graft count in the operation report.
- Take standardised photos and judge the result only after about 12 months.
- Be wary of « unlimited grafts » offers and prices that change on arrival.
Frequently asked questions
Is a graft the same as a hair?
No. A graft is a follicular unit that usually contains one to four hairs. The total number of hairs is therefore higher than the number of grafts.
How many grafts does a typical hair transplant involve?
ISHRS members reported an average of about 2,100 to 2,300 grafts per typical case in 2024. Your own number depends on the area to cover and your donor area.
Can I have as many grafts as I want?
No. Your donor area sets the limit. Taking too many grafts leaves a thin, patchy donor zone that cannot be restored.
Are more grafts always better?
No. Well-placed grafts in the right zones, with a reserve for the future, usually give a better long-term result than the maximum number in one session.
Do all transplanted grafts grow?
Most grow when they are harvested cleanly and handled well. Damage during extraction, drying out or rough handling can reduce growth.
Can I use beard hair if my scalp donor area is weak?
Sometimes. Beard hair keeps its own thickness and texture, so it is mainly used to add coverage in the crown or for repairs.
Why does my surgeon want to keep grafts in reserve?
Because hair loss often progresses. Reserve grafts allow a future session to keep the result natural as your native hair thins.
Will my donor area look thin after FUE?
Not if extraction is spread evenly and stays within safe limits. Over-harvesting or concentrated extraction can leave visible thinning.
Is a hair transplant cheaper in Tunisia or Turkey?
Both are significantly cheaper than Switzerland. The free quote gives the exact price and can compare the two destinations.
Your next step: request a free, personalised quote with photos of your scalp and donor area. Medespoir proposes a hair transplant in Tunisia or Istanbul, significantly cheaper than in Switzerland, with the exact price in the quote within 48 hours.
