Hair Transplant Scars: What FUE and FUT Leave, How Visible They Are and What Can Be Done

Part of our hair transplant guide. In July 2025 a patient on r/HairTransplants wrote: "I'm 1.5 years into my hair transplant journey. I got a low fade cut at the barbers yesterday and totally forgot about the scarring." (thread)

Every hair transplant leaves scars. FUE leaves many small round ones across the donor area, where the grafts were taken. FUT leaves one line.

How visible they are depends on how short you cut your hair, how many grafts were taken, how your skin heals and who did the work. This page covers what each method leaves, how scar repair works, what Thai clinics publish about scars and what patients report.

Hair Transplant Scars at a Glance

Do Hair Transplants Leave Scars?

Yes. The International Society of Hair Restoration Surgery (ISHRS) says: "It is important to know that both FUT (strip) and FUE results in scars." It explains why: "any incision whether by machine or hand that enters the skin beyond the most superficial of depths causes a scar to form."

On FUE, its patient article Is FUE Scarless? says "the idea of FUE being a scarless procedure is simply incorrect." A 2026 review in Frontiers in Medicine (Romera de Blas and colleagues) agrees. Each punch "leaves behind a small wound that heals with some degree of fibrosis, often imperceptible but occasionally manifesting as visible hypopigmented spots."

Journal wording varies. A 2020 abstract says extraction lets the surgeon "harvest grafts from the donor area without leaving a scar" (Epstein and colleagues), while a 2021 abstract says it "leaves a tiny circular scar over the donor area" (Garg and Garg). We rely on the ISHRS wording.

Three Thai clinics say the same on their own pages. Bangkok Hair Clinic says completely scar-free surgery isn't possible.

Thailand Hair Transplant Center in Chiang Mai calls the idea that FUE is scarless a common misconception. Yanhee International Hospital in Bangkok cites ISHRS and says FUE "leaves many small round scars instead of one line."

A clinic page that promises no scars is promising something ISHRS says doesn't exist.

Hair transplant scars are one risk among several. A 2025 systematic review of 45 articles (Khatib and colleagues) concluded: "Hair transplant surgery is generally safe. Pain, swelling, and edema at the donor site were the most often reported complications." Its abstract gives no donor scar rate, and the other risks are on our hair transplant risks page.

What FUE Leaves in the Donor Area

FUE takes follicular units out one at a time with a small circular punch, and each graft leaves one wound. How much donor hair a head can spare is on our donor area page.

Round Dots, One per Graft

ISHRS gives the punch range: "FUE uses micro punches that span from 0.7 to 1.2 mm in size to harvest these follicular units." Scar size is "directly related to both the size of the FUE punch used by the surgeon as well as the healing characteristics of the patient" (Is FUE Scarless?).

ISHRS puts the count in four words: "One follicle, one scar." Its FUT guideline sets 2,000 FUE grafts against a strip: "Instead of having more than 2,000 tiny 0.9mm diameter punctuate scars, there is a single linear scar." The 0.9 mm is the guideline's example punch size, not a measured scar.

ISHRS states the conclusion in Is FUE Scarless?: "follicle for follicle, FUE will actually leave MORE scarring in the donor area than a strip surgery that is harvesting the same number of follicles." Its worked example, in a separate article, compares 314 cm of cut edge for 1,000 grafts with a 1 mm punch against a 12.5 cm strip scar. The figures are example assumptions, and cut edge isn't the same as visible scar.

Sources state dot size differently, and they don't all measure the same thing.

Bangkok Hair Clinic's two pages give different ranges. Treat each clinic figure as that clinic's own statement.

Why a Shaved Head Shows Them

ISHRS says dots that are paler or darker than the skin around them may show when the hair is cut very short. They "may be a scar reaction or actual post inflammatory pigment changes, particularly in darker skinned individuals" (ISHRS).

The 2026 review calls the pale version "pinpoint white dots" and says they "tend to be more noticeable in patients with dark hair, darker skin phototypes, or those who prefer short hairstyles."

Dots are usually easier to miss than a line. ISHRS: "our eyes are drawn to patterns and the randomness of FUE excisions is far more difficult to see than a single, thin line that is right in the middle of the back of your head." If the donor hair is kept long, "neither scar is typically visible" (ISHRS).

Non-shaven FUE adds a point. BHI Clinic in Bangkok says "the distribution of tiny scars may be slightly less even compared to Shaven FUE," and Yanhee says the same. Our no-shave hair transplant page covers the trade-off.

Overharvesting: When the Donor Looks Thin

Where the grafts come from, and how many, also shows. ISHRS: "as more and more grafts are harvested the area may appear moth eaten. If grafts are taken too close together there may be an appearance of a scar."

Done poorly, ISHRS says, "the result can look worse than any FUT procedure that has gone wrong," and adds that the resulting donor destruction "can, and has, created problems" that can't be fixed (ISHRS).

The 2026 review calls overharvesting "one of the most characteristic donor site complications in FUE procedures." Its authors advise using "smaller punches (0.8-0.9 mm)," keeping a uniform extraction pattern with densities below 15% to 20% per session, and "respecting adequate spacing between excisions." That is their view with citations, not a trial result.

Thailand Hair Transplant Center says FUE donor scars "add up with each procedure." Planning the number of grafts for your stage of hair loss is on our how many grafts page.

Does DHI Change the Donor Scar?

Not according to two clinic blogs. Acibadem International in Turkey: "The harvesting step is identical: individual follicular units are extracted with a circular punch, one by one, leaving the same field of dot scars across the back of the head." Smile Hair Clinic in Istanbul says DHI "generally uses FUE-style follicle extraction" and shouldn't be marketed as a completely scar-free procedure.

DHI is a different way of placing grafts. Our FUE vs DHI page compares the two.

What FUT Leaves

FUT removes a strip of scalp from the back of the head and closes the wound, which leaves a line. Choosing between the methods is on our FUE vs FUT page.

One Line Across the Back

ISHRS gives the size of the strip: "FUT involves removing a strip of tissue 0.5 to 1.5 cm in width and from 5 to 30 cm long from the back of the head, which after having been removed, is closed with sutures or staples." That is the strip, not the healed scar.

ISHRS describes the result as "a long thin scar that may be seen with haircuts that are too short." If properly done, "many patients can still wear short hairstyles without a visible line scar being noticed by the casual observer."

In its strip versus FUE comparison, ISHRS says "the vast majority of patients who undergo strip harvesting have minimal scars that are easily concealed by the hair above the scar." It adds that "there are, however, some patients who have scars that have widened." Widening is the exception.

Sources state the width of the healed line differently, and two are clinic claims.

What Widens a FUT Scar

ISHRS: "By limiting the width of the strip to be taken and avoiding tension on the wound, the surgeon can minimize the donor scar." The FUT guideline adds: "Removing the strip under tension can result in a widened scar, and this can be unpleasant for the patient and difficult to correct."

A retrospective study of 30 patients (Nirmal and colleagues), assessed at least 3 months after surgery, found: "Scar width increased with increase in width of the donor strip. Patient satisfaction scores declined with larger strip widths."

ISHRS adds that "FUT scars heal better with each successive decade in life" (ISHRS). Thailand Hair Transplant Center lists what sets the final width: "surgical technique, wound tension, scalp characteristics, healing and individual scar biology." It adds: "no surgeon can guarantee an invisible scar."

Trichophytic Closure

Trichophytic closure is a way of closing the FUT wound so hair grows through the scar. The FUT guideline describes "creating a small step approximately 1mm wide and deep," after which "the transected hairs will grow through the scar."

In the 30-patient study above, "Double trichophytic closure yielded the most aesthetically acceptable scar." A case report of one patient (Park and colleagues) found "less scar in the columnar trichophytic suture part, compared with almost 7 mm of scar widening in the simple primary closure part." One patient shows what happened to that patient, not how the method performs in general.

Four Thai clinics describe the technique in their own words:

• Hairsmith Clinic, Bangkok: the technique "allows hair to grow directly through the scar line."
• DHT Clinic, Bangkok: "The wound is closed with double trichophytic technique and the stitches are removed in 10-14 days."
• Kamol Hospital, Bangkok: "trichophytic technique with absorbable sutures (that no need to remove) for tension free."
• Yanhee, Bangkok: "a millimetre of tissue is trimmed from one wound edge so hair grows up through the scar line."

Ask your surgeon which closure will be used and who will do it.

Repeat FUT: One Scar, Not Several

On a repeat FUT, ISHRS says "To avoid multiple scars many physicians who use strip harvesting employ a single scar technique even if multiple procedures are performed." Thailand Hair Transplant Center says FUT scars generally don't accumulate with each procedure the way FUE extraction scars do. Timing, future hair loss and donor limits are on our second hair transplant page.

How Short Can You Cut Your Hair After a Transplant?

There is no common standard. ISHRS gives the first figures below, and the rest are statements from clinics. Clipper guard numbers differ between brands, so each figure is attributed, and patients' own guard numbers are in the patient section.

FUT: Hair Length That Covers the Line

FUE: How Short the Dots Allow

Who shouldn't choose FUT? The FUT guideline lists "patients who worry about developing a linear scar, patients who prefer or require short hair, and those with a tight scalp." It also excludes "patients with a history of hypertrophic or keloid scarring or poor wound healing."

Thailand Hair Transplant Center frames the choice by hairstyle. "Someone who intends to shave the back and sides extremely short may prefer the distributed scarring associated with FUE," it says, while someone who keeps enough length to hide a line and wants to maximize long-term donor options may prefer FUT.

Transplants done without shaving are covered on our long hair transplant page.

If you plan to shave your head, say so at the consultation. The 2026 review says higher-risk patients "should be appropriately counseled preoperatively about the potential visibility of donor scarring, particularly if they plan to shave their scalp."

What Decides How Visible a Scar Is

The surgeon. ISHRS: "Choosing the right surgeon to perform your procedure is the single most important decision for every patient." It also says some cheap FUE offers mean "unlicensed technicians are unlawfully performing FUE harvesting," which it condemns, in a general statement that names no country.

Ask who will do each step. Our who performs hair transplant surgery page covers the roles.

Skin and hair. The Treatment Rooms London says: "Some patients have a higher risk of visible scars compared to others. These are due to hair types, hair thickness, hair and skin colours." None of the sources on this page measures donor scarring by Asian skin or hair type, and the statements about darker skin are general.

Thick or raised scars. The 2026 review lists the risk factors for abnormal scarring as "a personal or family history of abnormal scarring, darker skin phototypes, and previous keloid formation," and says that although keloidal scarring is "exceedingly uncommon and typically limited to case reports, diffuse fibrosis or thickening may occur in some patients." ISHRS says punches don't protect keloid-prone patients, because punch excision won't limit scar formation in patients with a predilection for keloids.

Tell your surgeon about any history of thick or raised scars. For high-risk patients the review suggests "a small test session with limited harvesting." Whether you are a candidate at all is on our am I a candidate page.

Smoking and diabetes. The review lists smoking, diabetes, inadequate surgical planning, overharvesting and excessive density among the risk factors for complications in general, not only visible scars.

How a Hair Transplant Scar Heals

No hair transplant study on this page gives a timeline for how a donor scar matures. These windows come from ISHRS and from clinic pages, and the clinic ones are each clinic's own statement. Healing varies by person.

Day-by-day care is on our aftercare page and week by week on our recovery timeline page.

Hair Transplant Scar Repair: Fixing or Hiding a Donor Scar

ISHRS lists the ways to correct a poor FUT scar: "re-excision and closure of the scar; transplanting into the scar using either FUE or FUT grafts; and/or scalp micropigmentation (SMP) or tattooing into the scar" (ISHRS). Each treatment has limits. If the whole result looks wrong, our failed hair transplant page covers repair and costs in Thailand.

Scalp Micropigmentation (SMP)

Smile Hair Clinic in Istanbul says SMP doesn't remove a scar. Instead, "pigment is placed into the scalp to reduce the color contrast between a pale scar and surrounding short hair."

ISHRS says SMP can visually diminish a scar's appearance and in some cases nearly erase it, for FUE dots and a FUT line alike. It also warns that scars are the most demanding and difficult place to put SMP, because "the pigment placed into a scar often spreads, fades, and changes color in unpredictable patterns."

Timing matters. ISHRS says SMP "should be avoided after hair transplantation for at least a year to give time for the newly transplanted hairs to grow." Since "healing takes a full year," SMP placed earlier "risks premature fading and suboptimal results."

How long it lasts depends on who you ask, and the sources cover different things.

Don't average them. ISHRS also says "There is currently no international licensing body for scalp micropigmentation practitioners." For an artist working outside a surgeon's office it advises looking for "clear, reproduced patterns of photos with consistent lighting and positioning."

Hair Transplanted Into the Scar

ISHRS lists grafts into the scar as a repair option. In its strip versus FUE comparison it says "FUE can be used to try to camouflage linear donor scars. This is considered by many hair restoration surgeons to be another excellent use of the technique." Covering a whole scar with follicular units, the FUT guideline notes, "requires using valuable donor hair."

Scar tissue limits what grafts can do. An ISHRS page on scars from injury, burns and disease, not donor scars specifically, says hair doesn't naturally grow in scarred skin where follicles have been destroyed, and "if the blood supply is inadequate, the transplanted hair follicles will die or be unable to function adequately."

Hairsmith Clinic in Bangkok says "the success rate may be slightly lower than a standard hair transplant" because "scar tissue often has a compromised blood supply." It adds that "a second session may be required to achieve the desired density," because the initial take rate on scar tissue can be unpredictable.

The same page says the cost depends on the size of the area and the technique.

ISHRS gives no survival or satisfaction figures for FUE into a donor scar. The nearest figure, 80.67% mean graft survival at 12 months, comes from a 15-patient study of scars from earlier scalp surgery (Yoo and colleagues, 2019). Those aren't donor scars, so it isn't a number to plan around.

Cutting the Scar Out and Closing Again

For a wide FUT scar, the FUT guideline says "the surgeon may consider scar resection with double-layered sutures, which would result in a thinner scar." It warns that "due to the stretch-back phenomenon, the scar may widen over time, resulting in minimal improvement."

The guideline also describes a newer "punching-out" technique, which "involves using a 1mm FUE punch to create multiple perforations in the scar, resembling a honeycomb," and gives no results for it. Smile Hair Clinic adds that revision doesn't guarantee a better result "because the new incision must also heal."

No Thai clinic page we read prints a price for scar revision surgery, so ask for a written quote.

Which Treatment Fits Which Problem (Our Reading)

This is our reading of the scar repair sources above, not medical advice. Your surgeon decides what fits your scalp.

• A pale line you see at your usual haircut: ISHRS lists SMP and grafts into the scar as options.
• A wide, stretched line: ask a surgeon about resection and about stretch-back, which the guideline says can leave minimal improvement.
• Visible FUE dots: ISHRS says SMP is often used to hide them.
• An FUE donor area that looks thin: ISHRS says donor damage can create problems that can't be fixed, so the questions below matter before surgery, not after.

What Thai Clinics Say About Scars on Their Own Pages

We read what these clinics publish about scars on their own sites. Nobody at AsiaPatient has had a procedure at, or visited, any of them. Everything in the table is the clinic's own statement.

Where a clinic page promises invisible or hidden scars, we haven't repeated the promise, because ISHRS says scarless surgery doesn't exist.

What Patients Report

These are public posts on r/HairTransplants and r/SMPchat. They are self-reports and no photos are shown here, so they are the patients' own descriptions. Each quote links to its thread, and good and bad accounts get the same room.

Patients Who Had Surgery in Thailand

A patient who had FUT in Bangkok wrote in March 2025, five months after surgery: "Scar has healed pretty well. I have my hair pretty short on the back and sides and you can see where the scar is." The same comment says "it's not major as the hair has grown on and around the scar." The patient recommends the clinic in the thread (thread).

Another patient, who says they had FUT in Bangkok, wrote in September 2024 at one year: "I can't get a photo of the scar bc I have way too much hair at the back to see it" (thread). In a reply: "the scar doesn't bother me, I can barely feel it let alone see it" (comment).

A patient who had FUE with around 3,000 grafts at HairTran in Bangkok wrote in February 2026: "Scars are inherent to hair transplant. They are far less visible with fue compared to fut but they still exists." And: "I can do high fade zero and it looks great. But I know other people who didnt get as lucky as me." (thread)

Patients Elsewhere, Good and Bad

A patient who had FUT and says their doctor was in Australia (comment) wrote in February 2026: "I honestly I was shocked at how pronounced my scar is. I need to really limit the clippers otherwise there's a giant smiley face on the back of my head." They say they will probably have a follow-up FUE to correct it (thread).

Accounts of FUE split. In February 2026 a patient who says they had FUE in London wrote: "I have no scars at all , I had a buzz for more than 6 months and people could not tell" (thread). Another commenter in that thread: "almost everyone gets scars even on FUE. how visible they are is up to the skill of your doctor/technician" (thread).

FUT accounts split too. A patient who had FUT twice wrote in January 2022: "I cut my hair to 1/2 or 3/8 of an inch in the back, same as I did before surgery. Scar is very hard to detect" (thread).

Another wrote in July 2023: "it was the worst decision of my life, hair loss of course continued progressing and now I can't wear my hair short (as looks best when you don't have much of it) because of the scar" (thread).

What Patients Say About Hair Length After FUT

Guard numbers differ between clipper brands. These are the patients' words, with months since surgery where they gave them.

Patients on Repairs

A patient wrote in March 2025 about a repair where the surgeon punched out tiny holes in the scar tissue and then stitched the scar shut: "It slightly reduced the width, but very dramatically evened out the scar to be much smoother and free of ingrown hairs" (comment).

The same patient later had FUE from the beard into the scar. Four months in, in July 2025, they wrote: "The back and right side are filling in nicely. I think I may need to go back for the left side since it still looks sparse but may be too early to tell (4 months in)" (comment).

A patient who had FUT in 2007 wrote in November 2025: "FUT was done in 2007. 3 scar revisions since by top plastic surgeons in North America. The other half healed well, not this half" (comment). On the third revision: "basically the third one didn't make a change positive or negative" (comment).

That is a single case, so don't read it as typical. A patient in the same thread who says they had seven FUT procedures wrote: "I've had seven and I have one scar" (comment).

Questions to Ask Before You Book

Take these to every consultation. They come from ISHRS, one Thai clinic's list of what it assesses before FUT, and patients. More general questions are on our consultation questions page.

• Visibility. "Will people notice my hair transplantation?" ISHRS says to ask this upfront because "a hair restoration surgeon can suggest options for making the transplantation less noticeable" (ISHRS).
• Who does what. ISHRS: "Who will be involved in performing my surgery, what role will they play, and what is their education, training, licensure, and experience performing hair restoration surgery?"
• Examples. The FUT guideline: "Providing images or videos that showcase examples of thin or wider scars can be helpful in educating the patient about potential outcomes."
• FUT assessment. Thailand Hair Transplant Center lists "scalp laxity, donor density, previous surgery, scar characteristics and future hair-loss pattern" as the assessment before FUT.
• FUE planning. Ask the punch size and the share of your donor density the surgeon plans to take. A commenter on r/HairTransplants advised requesting before and after photos or video "To check donor areas of other patients" (thread).
• Shaving. If you plan to shave your head, say so before surgery, not after.

How to read a donor-area photo? Acibadem International's blog advises: "Choose a surgeon based on their healed donor results at short hair lengths, not on which three-letter method they advertise."

Our reading of that advice, for any donor photo a clinic sends:

• The lighting is the same in every photo.
• The hair length and the months since surgery are stated.
• The surgeon in the photos is the one who would operate on you.
• An FUE donor area is photographed at the length you plan to wear.

Frequently Asked Questions

Do hair transplants leave scars?

Yes. The International Society of Hair Restoration Surgery (ISHRS) says there is no such thing as "scarless" surgery in hair transplantation. FUT procedures leave one linear scar, and FUE leaves many small round scars, one for each graft.

Is FUE really scarless?

No. ISHRS calls the idea "simply incorrect" and says that follicle for follicle, FUE leaves more scarring in the donor area than a strip harvesting the same number of follicles. The dots are harder to see than a line, but they are there.

Can I shave my head after an FUE transplant?

It depends on how many grafts were taken and how they were spread. ISHRS says patients are usually free to cut their hair as short as they wish if the total follicular units are limited. A 2026 review says patients at higher risk should be counseled before surgery about how visible donor scarring may be, particularly if they plan to shave.

How short can I wear my hair after FUT?

The ISHRS FUT guideline says patients typically need hair of at least 2-3 cm throughout life to cover the scar. Thailand Hair Transplant Center and Yanhee say about an inch, and DHT Clinic says at least 3 cm. Patients report guard numbers from 2, which one called too much, to 5 to 6.

How long until a transplant scar looks final?

ISHRS says healing takes a full year. Acibadem International's blog says scars remodel for 12 to 18 months. Neither figure comes from a hair transplant study, so treat both as guidance.

Can a FUT scar be fixed or hidden?

ISHRS lists re-excision and closure, transplanting FUE or FUT grafts into the scar, and scalp micropigmentation. The FUT guideline warns that a scar cut out and closed again may widen over time, leaving minimal improvement.

Does scalp micropigmentation hide hair transplant scars?

ISHRS says it can visually diminish a scar and in some cases nearly erase it, but that scars are the most demanding place to put SMP and pigment in a scar often spreads, fades and changes color. It advises waiting at least a year after a transplant.

Does DHI leave less scarring than FUE?

Two clinic blogs say no. Acibadem International says the harvesting step is identical, and Smile Hair Clinic says DHI generally uses FUE-style extraction. DHI is a different way of placing grafts, not of taking them.
