A hair transplant works by relocating healthy hair follicles from a permanent donor area — usually the back and sides of the scalp — to areas of thinning or baldness. Performed under local anaesthetic, the surgeon harvests individual follicles (FUE) or a strip of skin (FUT), prepares the grafts, creates tiny incisions at precise angles, and implants each follicle. The transplanted hair sheds, then regrows permanently over 12–18 months.
If you’re considering surgery, understanding exactly how does a hair transplant work removes much of the anxiety and helps you ask the right questions. This step-by-step guide walks through the whole process — from the science behind it to the day of surgery and the months of regrowth that follow.
What is the science behind a hair transplant?
The procedure relies on a principle called donor dominance. Hair follicles at the back and sides of the scalp are genetically resistant to dihydrotestosterone (DHT), the hormone responsible for pattern hair loss. When these resistant follicles are moved to a balding area, they keep that resistance — so the transplanted hair continues to grow for life.
This is why a transplant is permanent and why the donor area is so important. It is also why a transplant treats the symptom (the bald area) rather than the cause (genetic sensitivity), meaning existing native hair may still thin over time. Many patients combine surgery with medical treatment to protect their original hair.
What are the steps of a hair transplant?
A hair transplant follows a clear sequence on the day of surgery. While techniques differ, the core stages are the same.
- Consultation and design — your hairline is designed and graft numbers agreed in advance
- Preparation — the donor area is trimmed and local anaesthetic is applied so the area is numb
- Harvesting — follicles are extracted individually (FUE) or as a strip that is then dissected (FUT)
- Graft preparation — the team sorts and preserves the grafts under magnification
- Incisions — the surgeon creates tiny sites at the correct angle, depth and density
- Implantation — each follicle is carefully placed to mimic natural growth direction
- Recovery briefing — aftercare instructions are given before you go home the same day
The whole procedure typically takes between four and eight hours depending on the number of grafts. You stay awake throughout, and many patients read or watch something during the session.
FUE vs FUT: which methods are used?
The two established techniques differ mainly in how follicles are harvested from the donor area. Both can produce excellent, natural results in the right hands.
| Feature | FUE | FUT |
|---|---|---|
| Harvesting method | Individual follicle extraction | Removal of a thin scalp strip |
| Scarring | Tiny scattered dots | A single fine linear scar |
| Recovery | Generally quicker, less tightness | Slightly longer in the donor area |
| Best for | Shorter styles, minimal scarring | Maximising graft yield in one session |
FUE is the most popular choice today because it leaves no linear scar and suits shorter hairstyles. Variations such as Long Hair FUE can even avoid shaving the recipient area — our comparison of Long Hair FUE and standard FUE explains which suits different patients. Vinci’s exclusive surgical protocols apply to both methods to protect the donor area and maximise graft survival.
How many grafts will I need?
Graft numbers depend on the extent of hair loss and the area being treated. The figure is calculated during consultation by assessing your thinning pattern and donor density.
| Area of hair loss | Typical graft range |
|---|---|
| Receding hairline / temples | 1,000–2,000 |
| Front and mid-scalp | 2,000–3,500 |
| Crown | 1,500–3,000 |
| Full restoration | 3,500–6,000+ (sometimes staged) |
These ranges are illustrative — the right number for you is confirmed in person. Our approach to graft planning explains how density and donor supply are balanced for a natural result that lasts.
What happens during recovery and regrowth?
Understanding the timeline reassures most patients, because the early weeks can look surprising before the real results appear.
- Days 1–7: mild swelling, redness and scabbing around the grafts; gentle washing as instructed
- Weeks 2–4: scabs clear and the transplanted hair sheds — this is normal and expected, not a failure
- Months 3–4: new growth begins from the relocated follicles
- Months 6–9: noticeable density and coverage develop
- Months 12–18: final results, with full thickness and natural styling
Following aftercare carefully in the first weeks is essential to graft survival. Our detailed week-by-week recovery guide sets out exactly what to expect at each stage.
Is a hair transplant permanent and does it look natural?
Yes on both counts when done well. The transplanted follicles are permanent because they retain their genetic resistance to thinning. A natural look depends on the artistry of the procedure — the angle, direction and density of placement, and a hairline designed to suit your face.
It is worth being clear about what a transplant isn’t: it does not stop your existing native hair from thinning, and it cannot create more donor hair than you have. This is why honest planning matters. Poorly executed work can look “pluggy” or unnatural; our guide on how Vinci prevents unnatural results explains the difference careful technique makes.
Frequently Asked Questions
Is a hair transplant painful?
The procedure is performed under local anaesthetic, so the scalp is numb and most patients feel little to no pain during surgery. Some soreness, tightness or mild swelling is common for a few days afterwards and is easily managed with simple pain relief.
How long does a hair transplant take?
Most procedures take between four and eight hours in a single day, depending on the number of grafts being transplanted. Larger restorations may occasionally be split across more than one session for the best result.
When will I see results?
Transplanted hair sheds within the first few weeks, then regrows from around three to four months. Most patients see meaningful coverage by six to nine months, with final results at 12–18 months as the hair thickens.
Will the transplanted hair fall out again?
The initial shedding of transplanted hair within weeks is normal and temporary. Once the follicles regrow, the hair is permanent because it keeps its genetic resistance to thinning. Existing native hair, however, may continue to change over time.
Can anyone have a hair transplant?
Most people with a stable, healthy donor area are suitable, but candidacy depends on the cause and pattern of hair loss, age and overall health. A consultation is needed to confirm whether surgery or a non-surgical option is right for you.
