FUE — Follicular Unit Extraction

1. What is FUE — and what makes it different?

FUE stands for Follicular Unit Extraction — the extraction of individual follicular units. A follicular unit is the smallest natural growth unit of hair and contains 1, 2, 3, or 4 hairs simultaneously (FU1, FU2, FU3, FU4).

With the FUE method, these units are individually extracted from the donor area at the back of the head using a rotating or oscillating micro-needle (usually 0.7 to 1.0 mm in diameter). Each extraction takes a few seconds. After a sorting and preparation phase, the follicles are then inserted into pre-made micro-channels in the recipient area.

The crucial difference to the older FUT/Strip method: no skin strip is cut out. This eliminates the linear scar at the back of the head — an advantage that makes FUE particularly attractive for patients with short hair or the desire for maximum discretion.

The technique in detail

FUE is not just FUE. The quality of a treatment depends on three technical variables: punch diameter, micro-needle drive type, and recipient channel blade material.

Punch diameter

The hollow needle that cuts around the follicle is the most important tool. In modern FUE, we work with punches between 0.7 mm and 1.0 mm — depending on hair structure and follicle size:

• 0.7–0.8 mm — fine, thin hair, small follicular units (FU1, FU2)
• 0.85–0.9 mm — standard for mixed FU2/FU3 extraction
• 0.95–1.0 mm — dense, strong hair structure, FU3/FU4

A punch that is too small risks injuring the follicle ("transection"). A punch that is too large leaves visible micro-scars. We select the size individually — for some patients, we work with two or three punch sizes in parallel.

Manual vs. motorized

The needle can be driven manually by hand or by a motor. Both have their justification:

• Motorized (rotating or oscillating) — faster, more even cut, less fatigue. Standard for larger procedures.
• Manual — tactile feedback, more control with loose skin or particularly sensitive tissue. Advantageous for eyebrow extraction.

Sapphire vs. steel blade

In the recipient area, micro-channels are created for implantation. Sapphire blades are sharper than steel blades, create finer cuts, cause less tissue trauma, and allow for denser implantation. In our practice, we work exclusively with sapphire — steel blades are outdated.

Transection rate as a measure of quality

The transection rate (proportion of injured follicles during extraction) is the most important indicator of FUE quality. Good surgeons achieve values below 3%. Those who work without microscopic control can reach 15–20% — these grafts do not survive the transplantation.

Preparation — what matters before the surgery

Preparation begins not on the day of surgery, but weeks beforehand. What you do (or don't do) before directly influences the survival rate and healing.

2–4 weeks before the procedure

• Discontinue Minoxidil (1 week beforehand) — can alter microcirculation during surgery
• Pause blood thinners only in consultation with your doctor — discontinue Aspirin, Ibuprofen, Naproxen at least 7 days beforehand
• Critically review supplements — high doses of Vitamin E, fish oil, ginkgo, garlic can increase bleeding
• Reduce alcohol — completely avoid 3 days before surgery
• Limit smoking — nicotine impairs blood circulation to the scalp and thus significantly reduces the growth rate. Ideally, reduce or pause 4 weeks beforehand.

The day before surgery

• Wash hair thoroughly, no gel, no wax, no hair products
• Normal dinner — no need to abstain
• Go to bed early — the surgery lasts 4–8 hours, you want to be well-rested
• Prepare comfortable clothing: button-up shirt (no need to pull over the head), loose trousers

On the morning of the surgery

• Light breakfast — you will be awake during the surgery and will eat
• No excessive caffeine (1 cup is enough — otherwise blood pressure spikes)
• Take prescribed medications as usual, unless otherwise agreed
• Arrange for an escort home (even if you are fit to drive yourself — you will be tired)

What you should bring

• Personal medication list
• Water, small snacks for breaks
• Headphones and a charged laptop or tablet (movies, series, music)

2. How an FUE treatment proceeds

An FUE session usually lasts 4 to 8 hours — depending on the number of grafts to be transplanted. It is performed on an outpatient basis under local anesthesia in our practice. You will be awake throughout the entire procedure, able to eat, listen to music, or watch movies.

The five phases:

1. Preparation & Planning — Marking of the recipient zone, individual hairline design, shaving of the donor area (if necessary), photo documentation.
2. Local anesthesia — Donor and recipient areas are locally anesthetized. After a few minutes, the entire treatment zone is pain-free.
3. Extraction — Individual follicles are extracted with the micro-needle and stored in a special nutrient solution until they are implanted.
4. Channel opening — In the recipient area, micro-channels are created with very fine blades (or with sapphire blades for sapphire FUE) with precise angle and depth selection.
5. Implantation — The follicles are individually inserted into the channels, paying attention to growth direction, distribution, and density.

After the procedure, you will receive detailed aftercare instructions. The first 48 hours are the most sensitive phase — after that, healing usually proceeds without complications.

Aftercare — Day 1 to Month 18

The growth rate of your grafts is determined not only in the operating room but in the first 14 days thereafter. What you do (or avoid) directly determines the later result.

Day 1 (day of surgery)

• Painkillers as needed (Paracetamol allowed, ibuprofen-containing medications as instructed)
• Sleep with the upper body elevated (30–45° angle) — reduces swelling
• Do not apply anything to the scalp, no hat, no pressure
• Take antibiotics as scheduled

Day 2–3

• Swelling of the forehead may occur and shift downwards towards the eyes (normal — no need to worry)
• Continue to sleep elevated
• Wet compresses can alleviate swelling
• First careful cleaning in the practice

Day 4–10

• Daily cleaning according to exact instructions — careful dabbing with special shampoo, no direct jet of water
• Crust formation at the implantation points is normal
• Under NO circumstances scratch, rub, or manually pull off crusts — they will detach by themselves from day 7–10
• Office work on the PC possible again from day 3–4
• No sport, no sauna, no swimming, no sex (sweat and pressure)

Day 11–14

• Crusts should be completely detached
• First careful sports training possible from day 14 (light cardio)
• Continue to avoid sun exposure

Week 3–6

• Shedding phase: the transplanted hairs fall out. This is normal — the roots remain active.
• Scalp massage and, if necessary, PRP accompanying treatment possible
• Full sport suitability from week 4
• Swimming and sauna possible again from week 6

Month 3–4

• First new hairs become visible — initially thin, unpigmented
• First follow-up examination in the practice with trichoscopy and photo documentation

Month 6–8

• Significant progress visible, density increases cumulatively
• Second follow-up examination

Month 12–18

• Final result achieved — full density, final hair structure
• Final appointment with before-and-after comparison
• Consultation on maintenance strategy (PRP refresh, possibly medicinal stabilization)

Realistic growth rate with correct aftercare: 90–95%. With nicotine consumption, insufficient aftercare, or too early stress, it measurably decreases — to 70–80%.

3. Who is FUE suitable for?

FUE is the method of choice for most patients — but not for everyone. Suitability depends on the stage of hair loss, the quality of the donor area, and the medical history.

FUE is particularly suitable for:

• Men with androgenetic alopecia in stages Norwood II–V
• Receding hairline and thinning at the temples
• Thinning at the crown or beginning vertex baldness
• Women with hair loss according to Ludwig scale I–II — with preserved frontal hairline
• Correction of older transplants or scars
• Beard and eyebrow transplantations

Limited suitability for:

• Very advanced hair loss (Norwood VI–VII) — here, the donor area is often not sufficient for full restoration
• Active inflammatory scalp conditions
• Diffuse thinning over the entire scalp
• Certain connective tissue or autoimmune diseases

Whether FUE is suitable for you will be clarified in the initial consultation with trichoscopy and anamnesis.

4. Advantages and limitations of the method

Advantages

• No linear scar — not visible even with short-shaved hair
• Minimally invasive — no scalpel cuts, no stitches
• Fast healing — pinpoint micro-scars heal within 7–10 days
• Natural result — individually planned growth direction and distribution
• Permanent — transplanted hairs remain for life
• Outpatient — no hospital stay, home on the same day

Limitations

• Limited donor capacity — each donor area yields only a certain number of grafts without creating visible thinning there
• More time-consuming than FUT, as each follicle is extracted individually
• Not for advanced hair loss without a sufficient donor area
• Result requires patience — final result only visible after 12–18 months

Honest advice also means telling you when a transplant is not the right solution. In cases of very advanced hair loss, a combination with conservative therapies such as PRP or medicinal treatment is often more sensible.

5. Healing and results over time

The biological course after an FUE transplant follows a fixed rhythm. Understanding this course is important - because there is a good year between the procedure and the visible final result.

Day 0–14: Healing

Immediately after the procedure, small scabs form at the implantation sites. The scalp may be red and slightly swollen. Scabs completely detach after 7–14 days.

Week 2–6: Shedding Phase

The transplanted hairs fall out - this is normal and not an indication of a failed procedure. The follicles remain active and enter a resting phase.

Month 3–4: New growth begins

The first new hairs become visible. They are initially thin and unpigmented but gain thickness with each growth cycle.

Month 6–8: Significant progress

The transplanted area visibly fills out. The result is recognizable, but not yet final.

Month 12–18: Final result

Full density, final hair structure, natural look. From now on, the transplanted hair behaves like your own - growing, cutting, styling completely normally.

6. FUE in our practice

In our practice, every FUE transplantation is planned and performed by dermatologists — not by trained assistants. Consultation, procedure, and aftercare are all provided from a single source, in the same practice in the heart of Munich.

We deliberately focus on fewer grafts and more precision. Blanket numbers like "4,000 grafts" are not a medical quality feature — what matters is individual planning, the quality of the donor area, and the growth rate after 12 months.

Our standards for every FUE treatment:

• Individual hairline design by the operating physician herself
• Trichoscopy-based donor analysis before each procedure
• Micro-needles in patient-adapted sizes (0.7–1.0 mm)
• German hygiene standards, own operating rooms in the practice
• Aftercare appointments directly in the practice, not remote
• Lifelong availability for follow-up visits

Whether FUE is the right procedure for you is best clarified in person. In the initial consultation, we will examine your findings, discuss realistic results — and also honestly tell you if another therapy is a better fit.

Frequently Asked Questions

How long does an FUE session take?

Depending on the number of grafts, 4 to 8 hours, including preparation, breaks, and implantation. For 1,500 grafts: approx. 4–5 hours. For 3,000 grafts: approx. 7–8 hours. Larger procedures (4,000+) are often split over two days to minimize the out-of-body time of the follicles.

What is the growth rate for FUE?

With careful execution and disciplined aftercare: 90–95%. Clinical studies document values between 85% and 98%, depending on surgeon experience, transection rate, out-of-body time of follicles, and patient compliance during aftercare. We document the growth rate for each patient 12 months post-op via trichoscopy.

Do I have to shave my hair completely for FUE?

For classic FUE, usually yes — donor area to 1–2 mm. For smaller procedures (up to approx. 1,500 grafts), a partial shave is possible, where only a strip in the donor area is shaved and remains covered by the longer hair around it. For a completely unshaved treatment, we recommend the DHI variant.

When can I exercise again after FUE?

Light office work from day 3. Light cardio from day 14. Full strength or endurance training from week 4. Swimming, sauna, and contact sports from week 6. The reason: sweat, pressure, and increased blood pressure can affect the follicles that are not yet stably anchored.

What happens to the transplanted hair in the first few weeks?

It falls out — this is the shedding phase in weeks 2 to 6. Don't worry: the hair roots remain actively anchored in the follicle and begin to produce new hair again from month 3–4. Those who don't know this often panic — but it is medically expected.

When will I see the final result?

First visible change from month 3–4. Significant progress from month 6–8. Final result with full density between month 12 and 18. For some patients, the hair structure even refines until month 24.

Can I continue taking my old hair loss medications after FUE?

Yes — and in many cases, it is even recommended. Minoxidil and Finasteride act on the non-transplanted existing hair and can slow down its loss. This is important because otherwise, gaps can form around the transplanted area. We discuss the exact timing of resumption after surgery individually.

How much does an FUE treatment cost in Munich?

The costs depend on the number of grafts and the duration of the treatment. In a personal consultation, we will provide you with a binding, transparent cost plan. We deliberately refrain from opaque flat-rate offers — the costs depend on the individual findings, not on a marketing level.
