Procedure
Hair transplant (FUE, FUT, DHI, beard and brow)
A transplant moves balding-resistant follicles from the back and sides of the scalp, or the beard, into thinning areas; most grafts survive, but donor hair is finite and cheap clinics cause real harm.
Key takeaways
- It works because the donor hair resists balding. In a meta-analysis of 34 mostly observational studies, pooled graft survival was about 85% with micrografts and 93% with micro- plus minigrafts in non-scarring hair loss (Stoneburner 2020). Transplanted hairs often shed in the first month; with an implanter, about half shed by month 1 and 92% had regrown by month 6 (Lee 2001). The full result takes 10 to 18 months.
- It changes how others see you. In a randomized photo experiment, observers rated men after a transplant as 3.6 years younger and more attractive, successful and approachable (Bater 2016).
- Medication is still needed afterwards, because pattern loss continues in the hair that was not transplanted. In a double-blind trial of 79 men, finasteride from 4 weeks before to 48 weeks after surgery gave visibly better results (94% vs 67%) (Leavitt 2005). The European S3 guideline suggests combining transplantation with finasteride 1 mg (Kanti 2018).
- Donor supply is finite. One classic estimate is that the safe donor area is about 25% of the scalp and only about half of it can be removed, and over-harvesting leaves a moth-eaten donor zone (Kumaresan 2018).
- FUE versus FUT is about scars and logistics, not graft quality. FUT leaves one linear scar; FUE leaves many dot scars that are usually easy to hide (Gupta 2020). Marketing FUE as scarless is false (Rose 2024).
- "DHI" is a placement tool, not a different operation. It means loading grafts into an implanter pen rather than placing them with forceps (Speranzini 2023). No head-to-head trial shows better survival.
- Serious complications are rare in experienced hands but real. Large series report overall complication rates of 1.2 to 4.7% (Liu 2025; Salanitri 2009).
- Medical tourism is the biggest avoidable risk. Reported problems include unsupervised technicians and bait-and-switch practices (Haider 2025), and a cluster of linked Mycobacterium abscessus scalp infections after surgery at one Istanbul clinic (Jia 2026).
What it is
A surgeon (or, in poor-quality clinics, a technician) harvests follicular units from the back and sides of the scalp, or from the beard or body, and implants them into thinning areas.
| Technique | What happens | Trade-offs |
|---|---|---|
| FUT or strip | A strip of donor scalp is removed, stitched and dissected into units | Linear scar, but spares the rest of the donor area and suits long hair; keloid or thick scar in up to 15% (Liu 2025) |
| FUE | Individual units are cored out with 0.8 to 1.0 mm punches | No linear scar, short haircuts possible, but many dot scars and a risk of over-harvesting; harder in curly hair (Kumaresan 2018) |
| Implanter or "DHI" | Grafts are loaded into a pen and inserted | Less graft handling; slower and costlier; no proven survival benefit (Speranzini 2023) |
| Robotic FUE | A robot selects and punches units | In a 13-man split-donor trial, yield was 82% vs 90% and discard rate 10.7% vs 5.5% for manual FUE (Zhu 2024) |
| Beard or body hair | FUE from the beard or chest | Extends the supply when scalp donor hair runs short (Kumaresan 2018) |
| Synthetic fibre implants | Artificial fibres are implanted | Banned by the US FDA, poor-quality studies, complications; not recommended in the Japanese guideline (Manabe 2018) |
What the studies show
- Pooled satisfaction was 90 to 97% in non-scarring alopecia (Stoneburner 2020).
- Complications in a large scoping review: sterile folliculitis in up to 53%, persistent numbness up to 11%, infection up to 11%, shock loss up to 4.1% in the donor and 6.5% in the recipient area (Liu 2025).
- Recipient-site necrosis occurred in an 18-patient series, two thirds of whom smoked and who had about 3,900 grafts each (Ceran 2024). Donor-site arteriovenous fistulas are reported in case reports (Khatib 2025).
- Scarring alopecias: pooled graft survival was 83% at 1 year but 40% at 4 to 6 years (Yii 2025). In lichen planopilaris and frontal fibrosing alopecia, survival fell below 41% after year 2 (Palacios-Diaz 2026).
- Platelet-rich plasma added during surgery gave better graft survival in a 30-patient comparison, which is weak evidence (Xue 2025).
- Curly and coily hair: curved follicles make FUE harder and raise transection. In patients of African descent a device-developer study reported a mean transection rate of 3 to 6% with a skin-responsive technique (Umar 2023; the lead author holds device patents).
- Women: they present later with more diffuse thinning, need a work-up for systemic causes, and often do better with FUT to protect the donor area (Queen 2025).
How it's used in studies
In the Leavitt trial men took finasteride 1 mg/day from 4 weeks before surgery to 48 weeks after. A 2026 surgeon consensus covered restarting low-dose oral minoxidil 1 to 3 days after surgery and topical minoxidil on grafts at 7 to 14 days (Gupta 2026). New hair appears around month 4.
Side effects and safety
- Common: donor pain and swelling, folliculitis, numbness, temporary shedding of both transplanted and nearby hair.
- Rarer: infection, necrosis (smoking, diabetes and very large sessions feature in cases), keloid after strip surgery, and new lichen planopilaris or frontal fibrosing alopecia reported after surgery.
- Who operates matters. Cutting the scalp is surgery and should be done by a licensed physician, not technicians. Complications are rising where untrained staff do the harvesting (Haider 2025). The UK government notes deaths of British nationals in Turkey after medical procedures in general, and advises discussing plans with a UK doctor (GOV.UK).
- Follow-up gaps after travelling abroad delay diagnosis of infection (Jia 2026). Seek care quickly for a red, swollen, non-healing scalp.
Bottom line
A transplant is a durable cosmetic fix for stable loss in people with enough donor hair, but it is not a cure, and untreated native hair keeps thinning. Stabilize with proven medication for 6 to 12 months first (see the treatment ladder), confirm the diagnosis (see when to see a dermatologist), and check who will actually do the surgery. Medication around surgery involves finasteride and minoxidil. Discuss with a doctor.
