FUE Training and Tools

I’ve read your blog with interest, especially having just returned from the ISHRS at San Diego. Could you comment more about the types of punch biopsy that you use, and where one can purchase them. Also, can arrangement be made where I can get some hands-on/observation training on the FUE technique?

Any help would be appreciated.

I am generally not in a position to train doctors. It takes many months to learn and master the FUE technique. Generally, I believe that a year fellowship is the right solution for the doctor who wants to learn this process. Structured learning is the right way to learn. The instruments are not available for sale yet.

FUE Transection

Hello Dr. Rassman,

One of your patients just checking in to say hi and ask a simple question:

Its been 10 years since your famous article on FUE (you link it frequently on this site)

How have your transection rates improved since then?

Back when we originally defined this procedure and published it in a peer reviewed journal (see here), we classified patients in 5 different categories defining the difficulty in doing FUE and the transection rate. These groups still apply and there are occasional patients (under 10%) who are still not good candidates for FUE. In other words, the human physiology has not changed over time.

Some patients may NEVER be good FUE candidates. We still strive for improvements, and with Dr. Pak’s engineering and clinical background we have changed our technique with a much better instrument that we pioneered to minimize transection. We recently received a patent on this instrument. When we made the breakthrough years ago, we called it the FUE2. This technology combines injecting fluid into the wound around the punch simultaneous with the extraction. The actual instrument has an injection needle welded to it. This has allowed us to decrease our transection rate in most of the patients years ago that we called “FOX negative”. The instrument design also allows us speed in the extraction process. Thanks to these innovations, the procedure is more practical, more efficient, and just plain better than most other instruments available (at least in our hands). Note the quality of the grafts in this link. The grafts are beautiful shaped and clearly show no transection.

Transection rates of under 10% should be the norm and when the transection rates go up above this number, we address with each patient who is impacted by a less efficient process. We still occasionally perform our infamous FOX test, which is essentially a test of up to 10 grafts extracted and the transection rate examined in this test group so we can anticipate the transection rates in advance. Unfortunately, not many doctors offer this test and the world continues to believe FUE is the best way to go about surgery (without taking transection into the equation).

Worse still, many doctors may misrepresent their transection rates and claim numbers that are unrealistic in their hands, but for marketing reasons they make claims suggesting they are as good as the best doctors out there. I know of a few doctors that live in an illusion which reflects technical skills that are way beyond their reach… and we see their patients frequently in the office for a second opinion.

FUE vs FUT — Which is Better?

ImageThere is a question arising out of the hair transplant community which is becoming polarized and lining up for a fight: Which is better, FUT (Follicular Unit Transplant with Strip) or FUE (Follicular Unit Extraction)? Some doctors have already specialized in performing FUE alone, so their opinion is already made up. Some doctors new to the business entered the FUE market having never done an FUT strip procedure. That means that the nuances of quality control have not been learned (tricks to prevent graft damage from manipulation and drying).

I have had the opportunity to speak with some of these new doctors and they reported a substantial failure rate in their initial patients, but with time, they learned how to prevent damage and minimize transection of the grafts, and their results progressively got better. Their decisions on becoming hair transplant surgeons were initially made from a business mindset, under the assumption that the market demand would be there as they learned the process. This assumption is what actually happened. They also made the assumptions that the FUE technique would eventually be as good as the FUT technique over time. Again, this was a business, not a medical decision, and only time will tell these doctors if the quality of their work has met the needs of the patients.

ImageThe long term results with FUE (particularly on donor area damage in extensive FUE grafting) is not yet in. When we introduced the FUE technique in 2002 at the international meeting and in the Journal of Dermatological Surgery, there was not too much of an initial reaction, because the doctors who tried it quickly failed to get good quality grafts out. I remember two doctors in particular (names withheld) — one called me the first day after I returned from the meeting and I spent an hour on the phone explaining the subtle nuances that made it work for us. He thanked me, then quickly announced his new “pioneering invention”, the FUE technique, both on his website and through various press releases. Clearly he did not have the time to do more than one procedure and I felt sorry for that patient, a victim of a doctor’s greed for fame and money.


Another doctor who came out and quickly started offering FUE was more subtle about it, and it took longer to establish a presence in the market. His initial work produced many failures, some of which I saw in consultations in my office, and much of it through emails with pictures I received from the victims. For some doctors, FUE is about money and not about patient welfare.

ImageI predict that the history of FUE will parallel the history of the FUT strip procedure, which we pioneered in the early 1990s. As the FUT strip surgery caught on and as more and more doctors offered the procedure, performing the surgery on patient after patient, they too found that the initial results produced a high failure and complication rate. It took years to learn (1) how to get growth, (2) how to increase the number of grafts extracted and implanted safely in one session, and (3) how to avoid the terrible scar and donor wound complications (the worst being gangrene of the donor area). These three “HOW TOs” are the same issues with FUE that we are now confronted with. Only time will tell us what results we will get and only doctors who do both procedures will be in the best position to judge this comparison today.

Dr. Robert Bernstein (who also co-authored our original work on FUE), has since purchased and installed an FUE robot (Artas® System), which puts him in a unique position to draw conclusions to the question, “Which is Better, FUE or FUT?” He wrote the following text, which I totally agree with:

“I explain to patients that FUT (via strip) will give the best cosmetic results (more volume) since the grafts are of better quality (when using microscopic dissection, there is less transection and more surrounding tissue to protect the grafts) and better graft selection (the grafts can all be harvested from the mid-portion of the permanent zone) In contrast, in FUE you need approximately 5 times the area. Because of this large donor area requirement, some of the hair must be harvested from fringe areas and thus the hair will be less stable genetically. I relate that with subsequent FUT procedures we remove the first scar, but with subsequent FUE sessions we are adding additional scars, so over the long-term the cumulative scarring over large areas can present its own problems of visibility.”

“I explain that the main advantage of FUE is to have the option of wearing your hair very short (but not shaved). FUE is also appropriate for patients who are at risk for a widened donor scar (i.e., very athletic and muscular or with thin, tight scalps etc.). I relate to patients that, in my experience, Robotic FUE is superior to other FUE methods in that it is much more accurate and more consistent. It enables the doctor to extract grafts with less damage than with hand-held instruments or other automated devices.”

ImageDr. Bernstein, like the editors of this blog and other good doctors, focus on quality care, safety, integrity, and discussing a balanced view of the FUE vs FUT discussion with the patient. When presented to the patient considering this decision, we call this “informed consent” and it not only reflects basic courtesy and respect shown to the patient, it is a requirement of the laws of most states and countries.

The patient must be presented a balanced view of the risks vs rewards of any procedure offered and the alternatives available to him/her. There are many good doctors who share these views.

FUE Without Shaving the Donor Area?

Dr. Rassman,

Thanks for the good work of educating us on hairloss on this website. You may not recall but I came to your clinic in December last year. One of the main questions I asked was whether it was possible to do FUE without shaving the donor area. You showed me a picture of a patient with “stripped shaves” as a way of hiding the surgery.

Recently, I came across Dr.Cole’s website. The website talks of a technique in which FUEs can be harvested without shaving your hair. I find this an interesting prospect as I would not want to have evidence of my transplant when I go to work.

Is this something that you may consider doing at NHI?

Here is the link: Forhair.com

I must be missing something. I read the link you suggested, but it sounds like what we’ve been doing for years… which is to clip a small area of the donor to extract the grafts. It allows those having FUE to maintain their same hair style, as the hair just above the donor area will cover the clipped part. The link you sent seems to just talk about how Dr. Cole’s patients now don’t have to shave their entire head.

At NHI, we do not completely shave the head to do FUE, as shown in the photos here.

FUE vs Strip — A Technical Analysis

This comes from prominent New York hair transplant surgeon, Dr. Michael Beehner:

With FUE, it is easy to fracture the neck of the base of the follicle when the bulb is “naked” and then grasped for placement, while in microscopic dissection with a strip harvest, there is good fat around the base of the follicle and fracture of the hair follicle almost never occurs during placement. When all of the people placing the grafts have to grasp the naked follicle, I think this causes a kink on the end of the exposed follicle and may be accompanied by poor growth.

Quite frankly, I wish that, instead of our always talking to the patient about the choice between FUE and “strip” harvesting, I would rather talk about FUE vs. “microscopic dissection of grafts”, because this is where the biggest difference is between the two procedures. Also, the FUE often strips the end of the graft as it is being pulled out, leaving less tissue and fat on the end. With strip harvest and microscopic dissection, the doctor’s staff have total control on how that graft will be produced and we never see stripped grafts. Also, the fact that in a strip surgery, we are always taking the strip from the absolute richest center of the scalp where the best hairs are, this makes the choice difference for me a “no-brainer”.

I have no trouble convincing 95% of my patients who walk in seeking FUE to go with strip when I present the FUE problems to them this way. I explain all of these things and reassure them that many patients have almost undetectable strip scars.

We wrote about Follicular Unit Extraction (FUE) vs Strip (FUT) nearly two years ago: FUE vs FUT — Which is Better?

When you look at a follicular unit, you will see all of the anatomical parts that are traditionally created from a strip harvesting technique. All of the critical anatomy is preserved as the grafts are dissected under a microscope from the strip harvest. Damage, providing that the grafts remain hydrated, is rare and growth is excellent.

When FUE’s are done, the follicular units are not-infrequently disrupted in some manner, and these grafts may not grow as well as a result of the disruption. This is shown in some grafts that we put aside for trimming when a patient had the type of collagen that resisted the extraction in the FUE process. This is viewed here. Once these second class grafts are trimmed, they must be grasped with a forceps at the bulb or just above the bulb, which can fracture the hair shaft (this is what Dr. Beehner was talking about above).

With good instrumentation and considerable experience, FUE can be done as successful as with a strip; however 100% of patients do not have a tissue anatomy that allows such a clean FUE. This was discussed in our pioneering article that introduced FUE to the medical profession.

Fungus on Scalp

i had to move out of my home due to fungi spores outside home was over 5000 and was consuming the inside of new home also. i am very allergic and had to be put in hospital, i have been on flagyl for 3 wks now and i still have bacteria,and fungi internally and on scalp. is it normal to constantly pass black and red dots from scalp and is this scalp fungus? going bald,and intense itching for 6 months now. please give any suggestion. thank you so much

It sounds like you have some serious issues. I would follow the recommendations from the doctor who is treating you. It is impossible for me to give you any medical advice over the Internet, as I am not your doctor. I can only give general opinions as a doctor. I do not know what “black and red dots” you are passing on your scalp, and I would have to see them to get an idea of what you’re talking about. It certainly does not sound normal.

Again, you need to ask these questions to your doctor who can actually examine and see what those “black and red” dots are. Sorry.

FUE without taking finasteride

I did research and saw it’s important to take fin for a year prior to FUE, but did my research a little too late, and discovered this sub after I had my FUE a week ago…. It’s too late to turn back time, and I started taking fin now post-op, but I have anxiety that my FUE will be a waste and unsuccessful. Will my transplanted hairs survive if I never took any fin/min prior to FUE, but will continue to do treatment after my FUE?

FUE harvests the hair from the back and sides of the head which are never DHT sensitive, so finasteride has no impact on these hairs. If the FUE was done by a good surgeon with a good team, they will grow and last your lifetime; however, your native hair around the hair transplant may still be impacted by your balding process made worse by the FUE surgery. This is particularly relevant if you are in your early 20s, so I don’t do surgery on men under 26. The older you get, the more secure your native hair will be. Finasteride started prior to your FUE will protect the native hair in most men.

FUE vs FUT confused

I’m confused why people even consider FUE. FUT has clearly shown to be able to extract more follicles from the safe zone and have a higher survival rate. Our limiting factor is the number of hair follicles we have. So besides an unsightly scar (which we can wear our hair long to hide), why FUE over FUT?

For the men with advanced balding patterns like the Class 5-7 patterns, I personally believe that the strip surgery is better because you don’t develop a see-through donor area as the donor gets depleted with FUE when the number of total grafts extracted exceeds 3500 grafts. This applies to a man with medium weight hair and a normal donor density. Men with coarser hair and higher than normal donor densities can get more than 3500 grafts extracted safely with FUE

Full Contact Sports After a Hair Transplant

I train regulary in full contact fighting sports. How long would I be out from training after a hair transplant???

If your surgery was done using the FUE technique, 7-10 days should be adequate (or until the scabs have gone away) before resuming your training. For a surgery done using the strip technique, I would wait 4-6 weeks.
