Hair transplant surgery permanently relocates follicles from your donor area to thinning zones, producing results that last a lifetime. Three primary techniques dominate the field today: FUE, FUT, and DHI. Each has distinct advantages, limitations, and ideal use cases. This chapter breaks down the mechanics, recovery, and cost of each method so you can match the right technique to your situation.
The Three Main Techniques
All hair transplant methods follow the same core principle: extracting healthy follicular units from the permanent donor zone (back and sides of the scalp) and implanting them where hair has been lost. The differences lie in how grafts are removed and placed.
| Feature | FUE | FUT (Strip) | DHI |
|---|---|---|---|
| Full name | Follicular Unit Extraction | Follicular Unit Transplantation | Direct Hair Implantation |
| Extraction method | Individual circular punches (0.7-1.0mm) | Linear strip excision | Individual punches (like FUE) |
| Implantation method | Pre-made recipient channels | Pre-made recipient channels | Choi Implanter Pen (no pre-made channels) |
| Scar type | Small dot scars | Linear scar (hidden by hair) | Minimal dot scars |
| Max grafts per session | Up to 5,000 | Up to 4,000 | Up to 3,500 |
| Graft survival rate | 90-95% | 90-95% | 90-95% |
| Recovery time | 7-10 days | 10-14 days | 7-10 days |
| Donor shaving required | Yes (usually) | No | Yes (usually) |
FUE: Follicular Unit Extraction
FUE is the most widely performed transplant technique worldwide. The surgeon uses a micro-punch tool (0.7-1.0mm diameter) to extract individual follicular units one at a time from the donor area. These are then placed into tiny channels created in the recipient zone.
How FUE Works
- Donor preparation. The back of the scalp is shaved and numbed with local anesthesia.
- Extraction. A motorized or manual punch tool scores around each follicular unit. The surgeon then lifts it free with forceps. A skilled team extracts 1,000-1,500 grafts per hour.
- Graft storage. Extracted grafts are stored in a chilled holding solution (typically Hypothermosol or ATP-supplemented saline) to maintain viability.
- Channel creation. The surgeon creates recipient sites using Sapphire blades or steel slits, controlling depth, angle, and direction for natural-looking results.
- Placement. Grafts are carefully inserted into the channels. This step determines the final aesthetic outcome.
FUE Advantages
- No linear scar, allowing short hairstyles.
- Faster recovery (7-10 days to normal activities).
- Can harvest from body hair (beard, chest) in select cases.
- Lower post-operative discomfort compared to FUT.
- Up to 5,000 grafts in a single session with an experienced team.
FUE Limitations
- Requires shaving the donor area in most cases.
- Longer operating time for high graft counts.
- Higher per-graft cost than FUT in many clinics.
- Transection rates can be higher with less experienced surgeons.
FUT: The Strip Method
FUT involves removing a narrow strip of skin from the donor area, typically 1-1.5 cm wide and 15-25 cm long. Technicians then dissect this strip into individual follicular units under microscopy.
How FUT Works
- Strip measurement. The surgeon marks a strip across the mid-occipital donor zone, sized to yield the required number of grafts.
- Excision. The strip is removed under local anesthesia.
- Closure. The wound edges are sutured or stapled. Trichophytic closure techniques minimize visible scarring.
- Dissection. A team of technicians uses stereo microscopes to separate the strip into individual follicular units. This preserves graft integrity at high rates.
- Channel creation and placement. Same as FUE from this point forward.
FUT Advantages
- No donor shaving required.
- Lower transection rate (grafts are dissected under magnification).
- Typically lower cost per graft than FUE.
- Efficient for high graft counts in a single session.
- Better graft quality in some cases due to microscopic dissection.
FUT Limitations
- Leaves a linear scar (can be hidden with hair longer than a #3 guard).
- Longer recovery (10-14 days) with tighter sensation at the donor site.
- Limited by scalp laxity for repeat procedures.
- Slightly higher post-operative discomfort.
DHI: Direct Hair Implantation
DHI is a refinement of FUE where extracted grafts are loaded directly into a Choi Implanter Pen. This tool creates the recipient channel and places the graft in a single motion, eliminating the separate channel-creation step.
How DHI Works
- Extraction. Same as FUE using micro-punch tools.
- Loading. Each graft is immediately loaded into a Choi pen by a technician.
- Implantation. The surgeon inserts the pen tip into the scalp and deploys the graft in one motion. Multiple pens are rotated to maintain workflow speed.
DHI Advantages
- No need for pre-made channels, reducing trauma to the scalp.
- Potentially higher graft survival due to shorter time outside the body.
- Greater precision in angle and direction control.
- Excellent for hairline refinement and increasing density between existing hairs.
- Minimal bleeding during implantation.
DHI Limitations
- Maximum session size is lower (around 3,500 grafts).
- Generally the most expensive technique.
- Requires a larger surgical team (multiple pen loaders).
- Surgeon fatigue can be a factor in longer sessions.
Technique Selection by Norwood Stage
The right technique depends on your specific situation. Here is a general guideline:
| Norwood Stage | Grafts Needed | Recommended Technique | Rationale |
|---|---|---|---|
| 2 | 800 - 1,500 | DHI | Small session, precision hairline work |
| 3 | 1,500 - 2,200 | FUE or DHI | Moderate count, hairline focus |
| 3V | 2,000 - 2,800 | FUE | Covers temples and crown efficiently |
| 4 | 2,500 - 3,500 | FUE | Good balance of speed and results |
| 5 | 3,000 - 4,500 | FUE (possibly split sessions) | High count, single or dual session |
| 6 | 4,000 - 6,000 | FUE + FUT combo or multi-session FUE | Maximizes graft yield |
| 7 | 5,500 - 7,500 | Multi-session FUE + FUT + consider SMP | Comprehensive multi-approach strategy |
The Surgery Timeline
Understanding what to expect at each phase reduces anxiety and helps you plan time off work.
Pre-Operative (2-4 Weeks Before)
- Stop blood-thinning medications and supplements (aspirin, vitamin E, fish oil) per your surgeon's instructions.
- Avoid alcohol for at least 72 hours before surgery.
- Continue finasteride and minoxidil unless your surgeon advises otherwise.
- Arrange transportation home (you cannot drive after sedation).
Day of Surgery
| Phase | Duration | What Happens |
|---|---|---|
| Preparation | 30-60 minutes | Hairline design, marking, anesthesia |
| Extraction | 2-4 hours | Donor area harvesting |
| Break | 30-60 minutes | Lunch break (you are awake throughout) |
| Implantation | 3-5 hours | Graft placement in recipient area |
| Wrap-up | 15-30 minutes | Bandaging, post-op instructions |
Post-Operative Recovery
| Timeframe | What to Expect |
|---|---|
| Days 1-3 | Swelling, mild discomfort, prescribed pain management |
| Days 4-7 | Scabbing at graft sites, swelling subsides |
| Days 7-10 | Scabs begin falling off (FUE return to work) |
| Days 10-14 | Suture removal if FUT, most visible signs resolved |
| Weeks 3-4 | "Shock loss" of transplanted hair (normal) |
| Months 3-4 | New growth begins to emerge |
| Months 6-8 | Noticeable improvement, approximately 60% of final result |
| Months 12-18 | Full result visible with mature hair thickness |
Graft Survival and What Affects It
The standard graft survival rate across FUE, FUT, and DHI is 90-95% with an experienced surgeon. Several factors influence where you fall within that range.
Factors that improve survival:
- Experienced surgical team with low transection rates.
- Short out-of-body time (grafts kept under 4 hours from extraction to placement).
- Proper graft storage solution maintained at 4 degrees C.
- Gentle handling by trained technicians.
- Good blood supply in the recipient area.
Factors that reduce survival:
- Excessive graft drying during the procedure.
- Trauma from forceps or rough handling.
- Placing grafts into heavily scarred tissue.
- Smoking (reduces blood flow to the scalp).
- Failure to follow post-operative care instructions.

Questions to Ask Your Surgeon
Before committing to any surgical approach, ask these specific questions during your consultation:
- How many procedures of this type have you performed?
- What is your average graft survival rate?
- Can I see before-and-after photos of patients at my Norwood stage?
- What is your transection rate for FUE?
- How do you store grafts during the procedure?
- What is your maximum comfortable session size?
- Do you perform the extractions yourself, or does a technician?
- What is your revision rate?
- How do you handle complications?
- What is included in the quoted price (medications, follow-up visits, PRP)?
A confident, experienced surgeon will answer these questions openly. Hesitation or vague responses are red flags.
Combining Techniques
For patients at Norwood 5 and above who need maximum graft counts, some surgeons recommend combining FUE and FUT. This approach harvests grafts via strip excision first, then supplements with FUE extraction from areas around the strip scar. It can yield 6,000-8,000+ grafts in a single day.
This combination works best when:
- You need more than 5,000 grafts.
- Your scalp laxity supports strip harvesting.
- You are comfortable with both dot and linear scarring.
- The surgical team is experienced in both techniques.
