FUE – Is There a 0.75mm Dull Punch? – Hair Loss Information by Dr. William Rassman

Is there a 0.75 mm dull punch? Or is it possible to use Dr. James Harris’ two step technique with a 0.75 mm tool, so there would be a lot less transected follicles?

Follicular extraction is a very delicate and technically challenging process with its transection risks. As you can imagine, smaller diameter instruments will have more transection rates. It is a balance between technology and technique that will ultimately determine the acceptable transection rate. I have personally developed and used a 0.75mm and even a 0.70mm dull and sharp punch utilizing many techniques (including the two step technique). It is my opinion that the technology has not been perfected to my satisfaction for the entire Follicular Extraction process and damage with the an instrument of this size is generally unacceptable. With the current state of technology, acceptable FUE procedures can be done with a 0.9mm diameter punch.

0.6mm Tool for FUE – Hair Loss Information by Dr. William Rassman

Hello or “Hej” – as we say in Sweden.

I did read a post from you talking about FUE instruments, you use 0.9mm and smaller tools will cause greater follicular holocaust, you said.

Recently I did read a blog entry from you where you talked about FUE and the development of smaller tools.

I’m confused. Here in Sweden we have an intresting option, 0.6mm. Is this pure nonsense or could this surgeon be that good? Method is called “FUE plus” and is said to transplant 120-180 hairs / cm2.

I did notice that you said that 200 hairs / cm2 is the original density provided by the “man above”.

Why increased follicular holocaust when using smaller instruments?

I am hopeful that some breakthrough will come about that will allow smaller instruments to be used, but alas I have not seen them yet. Without knowing the doctor who proclaims such miraculous instruments, as a betting man, I would wager that some lack of proper representation is the case here. Add to such a wonderful instrument, the ability to achieve within 90% of God density and you have FUE God Plus. That means that some doctors can improve on what God might do if he (or she, depending on your beliefs) was a transplant surgeon here on earth.

Will FUE Procedure Limit My Donor Site? – Hair Loss Information by Dr. William Rassman

Dear Dr. Rassman,

I am considering having a transplant procedure at your clinic. My preference would be to have the fox procedure since I would like the option of a very short haircut and am very physically active…. swimming, etc. and want the least amount of scar detection.
My question is this: Will having a fox procedure possibly limit my donor site options years down the line when I may need to come back to fill in other areas?

Thanks!

Everyone has a limited donor bank of hair and FUE will deplete that donor bank just like strip harvesting will do. The question I’ve been asked a few times is: Will there be more donor area with FUE than with traditional strip harvesting? The simple answer is only a guess as no one to my knowledge has pushed the donor supply far enough to find out the answer to that question.

Hair Loss InformationWill FUE Scars Be Noticable? – Hair Loss Information – Balding Blog

If I get the FUE procedure, to fill in the scar on the side of my head, will the fue scars be noticeable? I do a lot of television commercials and stuff on TV, so I really need it to not be detectabe, because I constantly have people doing stuff with my hair, and parting it in all sorts of ways. What I’m trying to say is, will the fue scars really be detectable if I want to have braids or my hair up? My agent actually told me I should get this scar repaired, and I really want to find the best, and I heard you are one of the best, and I’m really worried, becuase I don’t know what to do.
(The scar is not that big at all but my agent is bugging me about it).
PS- I got it when i fell against a desk when I was five. 🙂

Many doctors claim their expertise in Follicular Unit Extraction (FUE). Thank you for the complement. You may want to read the first article on the follicular extraction technique, which I co-wrote and was published in 2002 — Follicular Unit Extraction: Minimally Invasive Surgery for Hair Transplantation.

All incisions on the skin will produce a scar. However a FUE scar is so small, it would be virtually undetectable especially among your scalp hair. Furthermore, in covering up your desk accident scar, FUE would be an ideal technique from its minimal invasiveness to its fast healing times.

If you are interested you should set up a consultation so that the entire procedure can be explained in detail. You may also be interested in coming to one of our monthly open house events so that you can potentially see a patient who has had a FUE procedure.

FUE with a 0.75mm Instrument – Hair Loss Information – Balding Blog

Hi Doc,

Quick question regarding your “FUE Scars” response on May 30th. Are any tools under research or developement (at NHI or anywhere else) that will leave wounds in the 0.75 mm or less range? Or does “impractical” mean “impossible?”

Thanks!

CommandentsThere are some doctors using a 0.75mm sharp punch for FUE which is smaller by a factor of 30% from the 0.9mm punch. The follicular holocaust is very large. If it were reliable, I would be using it. Some doctors are telling their audience of patients that they CAN do this successfully with a 0.75 mm sharp punch. I am just a mortal and will not delude the public into believing what they may want to hear, or selling them a ‘bill of goods’ that I believe promotes the business at the patient’s expense.

If the technique can be perfected (we are trying to do just that), then it would be superior to what we do now with a 0.9mm instrument, because the wound would be much smaller, faster healing (now it heals in 5 days), create a smaller scar (now the scars are 0.9 mm round) and possibly would allow more harvested follicles. But alas, the technology is where it is now, that is, except in those doctors who promote their godly likeness.

Doctor Advised Against FUE Due to Healing Dangers – Hair Loss Information by Dr. William Rassman

Hi Doctor,

I have been adviced by a hair transplant surgeon against FUE, instead he suggested FUT.

The reason he gave was – the scars of FUE, which are generally left open to heal are very dangerous in weather condition like south asia. The scars are prone to get infected. Also he mentioned about various types of sealing but he also added that it doesnt help much.

He advocated FUT over FUE for- its less prone to infection, it takes less time, its costing much less and the it suitable for large number of grafts (I need around 2000 grafts on frontal area).

I am confused as I dont want the scar involved in FUT, but want a safer procedure.

So is FUT more safer/better suited alternative than FUE for my condition?

First, if you are clean and wash your hair regularly, FUE is not a problem even in wet or warm climates.

I agree with your doctor otherwise. The FUT is less expensive, easier to get larger sessions, and probably in his hands, safer than FUE. I personally try to tell my patients that scarring above 3mm occurs in less than 5% of patients. The use of a trichophytic incision and fascial closures as discussed in this blog, should address the scarring risks in most patients.

Hair Loss InformationI’ve Had 7 Strip Surgeries – Hair Loss Information – Balding Blog

ive had about 6 or 7 full strip procedures over the past seven years and have developed a scar that runs almost ear to ear and is an inch wide!

My surgeon has tried twice unsuccessfully to cut out the scar. There feels like very little excess tissue when i try and pinch. Im a dentist and am sure the tension from looking downwards post surgery was a factor although my surgeon says no. He is now talking about FUE from my chest. Would i be better suited seeing a plastic surgeon. He doesnt think anyone could achieve a better scar result. Ive had 2 colleagues get similar scars from the same doctor. Any advice would be greatly appreciated.

You must be careful here. Do you want to continue on a never ending process from surgery to surgery? There are creative options including:

  1. FUE — but not from the body, rather from the scalp where hair is active 85% of the time, rather than 20% of the time as with body hair
  2. Balloon expanders which can reduce scars very nicely if there is reasonable donor hair

Send me pictures (which I will keep confidential) and then I can offer you general advice about what is possible and what is not. You might consider coming to California after I get your photos for a one-on-one consultation if the photos lead me to believe that there may be a good solution for you.

I Want To Use Leg Hair To Fill in A Small Scalp Scar – Hair Loss Information by Dr. William Rassman

(female) Hi, I just wanted to say that I really appreciate the feedback you gave me about filling in the small scar on my head. I do however have another question. Since the scar on my head is so small, and I really don’t want to damage any further follicles on my head, is it possible to extract a few hairs from my leg or the back of my leg, and use it to fill in the scar? Because the hair on my legs doesn’t really differ from the hair on my head. And if transplanted, would the hair grow the same length as the rest of the surrounding hair?

Leg LampLeg hair has longer sleep cycles (as does most body hair) than scalp hair and that means that most of the hair is in its sleep cycle and not showing its presence. If you transplant 10 leg hairs and watch them grow, only about 2-3 of them will be evident at any one time (the others are there, but in telogen phase). Body hair also grows at different rates and it may not grow to regular scalp hair length. Furthermore, leg hair does not have the same quality and caliber as your scalp hair. More importantly, even if leg hair transplantation works, are you willing to live with a surgical scar on your leg?

The traditional FUE procedure (on the scalp) is a better solution and the hair is exactly the same quality that exists around it. In addition, it has only a 10-20% sleep phase at any one time. Although your idea sounds interesting, it is not a worthwhile endeavor.

Stretching Wounds and Scars – Hair Loss Information by Dr. William Rassman

How will these new wound closures you discussed in this blog impact people who have scars that stretch? I have scars that stretch every place I have had a surgery, including my hair transplant scar.

A trichophytic closure will not work if the wound widens more than 2-3 mm, because the hair growth from the trichotomy will only grow up to 2-3 mm from the edge of the wound where the trichotomy was done. The stretching may be helped by a sub-fascial closure below the occipitals muscle fascia. The tension reduction of such closures has value in reducing the wound size, but not necessarily in obliterating it. You might have some form of Erlos Danlos Syndrome (see here, here, and here), which comes about from defective collagen by its very nature. The story of EDS is not black and white, for I believe that some people have small amounts of this defective collagen and these people are the ones that may get stretching of the scars. In such situations, even the sub-fascial closures will not work, because eventually the body must heal the wound and as the sutures dissolve, the value of the sutures that hold the wound together will decrease over time.

Scars are at times a price one pays with surgery. For strip harvesting, this could be a price you will pay. If you have FUE harvesting (Follicular Unit Extraction), then this stretched scar problem should not become an issue with regard to your healing, as there is no large line scar to stretch.

Now with that said, putting the scar issue in perspective, the scar only exceeds 3 mm in about 5% of cases. If that happens and it bothers the patient, then I make this my problem as well and we work to solve the problem with whatever it takes.

Hair Loss InformationFUE Scars – Hair Loss Information – Balding Blog

Do FUE procedures form scars?

Block Quote

Yes, there are scars anytime the body is invaded by the surgeon, or any time you cut yourself. The scars come about when the edges attempt to close the gap. The FUE scars are circular, so the size of the scar somewhat reflects the size of the wound. To answer the question appropriately, let’s talk basic math and then convert the math to logic.

The chart here shows the size of the cutting punch and compares the size of the wound that is created. The scar reflects the size of the wound.

 

Diameter Area % change from smallest wound size
0.75mm 0.44mm square (baseline)
0.9mm 0.64mm square 44 % larger than 0.75
1.0mm 0.79mm square 78% larger than 0.75
1.5mm 1.77mm square 300% larger than 0.75

 

The reality of these number are that the 0.75mm leaves almost no scar, because the edges co-apt and there is minimal secondary healing as the scar fills from below as the side skin grows over it. With all of the wounds from strip harvesting, the scars are long and the wound is much larger. Such ‘line’ wounds can be seen when the scalp is shaved.

The 0.75mm wounds are impractical, but the 0.9mm wounds are the standard used in my practice. So in answer to your question; scars are related to the size of each wound. The smaller the wound for FUE (for example), the smaller the instrument used by the surgeon, the smaller and less noticeable will be the wounds in their final healing phase. Please see this previous post, Size of FUE Procedure, for discussion on actual yield rates. If only a needle is used (like the one you get with a flu shot) I sincerly doubt that you will ever find the scar with the naked eye.
