Synopsis: Hair restoration has advanced dramatically in the past 25 years, most recently with the growing popularity of FUE. The challenge of FUE is that the grafts are more fragile compared to the follicular units generated in traditional FUT/strip procedures. Innovations such as the ARTAS Robot and other devices attempt to address this problem. With the increasing participation of ISHRS members – now 1,200 strong – progression in this field should continue at an accelerating pace.
A recently published study is the first to measure the perceived benefit of hair transplantation on a patient’s age, attractiveness, successfulness, and approachability – key factors that play an important role in workplace and social success. The pilot study, published in the Journal of the American Medical Association Facial Plastic Surgery, found that hair transplant recipients were perceived by others to be 3.6 years younger following their hair restoration surgery. The data indicate that the person’s attractiveness, successfulness, and approachability also showed statistically significant positive changes as a result of hair restoration surgery.
Synopsis: Follicular Unit Hair Transplantation in “Surgery of the Skin: Procedural Dermatology,” is Dr. Bernstein’s third update of the chapter in the core surgical textbook for dermatologic training programs. The chapter covers a range of topics including: the basics of hair transplantation, detailed descriptions of both follicular unit transplantation (FUT) and follicular unit extraction (FUE), the importance of patient evaluation in advance of surgery, and aesthetic considerations in hair transplant design. Robotic FUE is included in the chapter for the first time as a hair transplant technique.
Synopsis: When considering Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE) procedures, a person’s age and the ability to assess the permanence of the donor area are important variables in determining surgical candidacy. This FUT case study examines the importance of these variables in the patient evaluation.
Synopsis: This is a newly revised edition of the popular Hair Loss & Replacement for Dummies. The 2011 edition presents the latest information on a variety of topics of interest to those suffering from hair loss. The updated edition book discusses the latest in laser light and medical treatments for hair loss, the recent advances in Follicular Unit Hair Transplantation and the new, minimally-invasive hair transplant technique, Follicular Unit Extraction.
Synopsis: Dr. Bernstein’s newly revised chapter, Follicular Unit Hair Transplantation, in “Surgery of the Skin: Procedural Dermatology,” a core surgical textbook for dermatologic training programs, covers a wide range of standard topics including; patient evaluation, surgical planning, operating techniques and aesthetic considerations in hair transplant design. New topics include: follicular unit extraction, eyebrow and eyelash transplantation, long-hair transplants, trichophytic closures, automation and hair cloning.
Follicular unit extraction is a technique of removing one follicular unit at a time from the donor region. The most important limitation of this hair transplant procedure is a high transection rate during the extraction process. In this clinical study, the authors transplanted different parts of transected hair follicle when harvesting with the Follicular Unit Extraction (FUE) technique. Five male patients participated in the study.
In each patient, three boxes of 1 cm2 were marked at both donor and recipient sites. The proximal one-third, one-half, and two-thirds of 15 hair follicles are extracted from each defined box and transplanted in recipient boxes. The density is determined at 12 months after the procedure.
The authors concluded that the survival rate of the transected hair follicles was directly related to the level of transection. The authors demonstrated that even though some of the transected parts of the follicles can survive after being transplanted to the recipient site, the growth rate is not satisfactory and the hair is thinner than the original follicles. As a result of this study, the researchers recommend that the hair transplant surgeon does not transplant the sectioned parts and that they should be careful with the patients whose transection rate is high during Follicular Unit Extraction procedures.
Synopsis: Important information for men and women of virtually all ages anxious to preserve their full head of hair, put the brakes on balding, or explore the safest and most reliable hair replacement techniques currently available. The book offers readers not only the full gamut of modern-day hair-care options, but crucial tips on how to avoid unscrupulous hair transplant doctors and potentially harmful products as well.
Synopsis: The ability to achieve full cosmetic benefit in follicular unit hair transplantation depends upon a number of factors including proper patient selection, accurately assessing the patient’s donor supply, appropriately designing the hair line and correctly distributing the grafts. This paper reviews the major mistakes that doctors make in these key aspects of the hair restoration process and advises the practitioner on how to avoid them so that the patient will achieve the best possible results.
Synopsis: Running, continuous sutures and metal staples are the two most common closures used by hair restoration surgeons today. This commentary discusses the pros and cons of various suture and stapling methods and makes an argument that, with new advances in techniques, staples are possibly the best means of closing the donor wound during a hair transplant procedure.
Synopsis: In 1998, a group of hair restoration surgeons proposed a classification for follicular unit hair transplantation and mini-micrografting techniques, to improve communication between physicians and their patients. With recent advances in techniques, a number of new terms are being used that do not have clear definitions. This paper expresses the author’s opinions on which of these terms are useful and should be incorporated into the original classification and which are confusing and should be abandoned. The authors also suggest concise definitions for these new terms.
Synopsis: Densitometry and video-microscopy are techniques that analyze the scalp under high-power magnification to give information on hair density, follicular unit composition and degree of miniaturization. They can be used to help evaluate a patient’s candidacy for hair transplantation and help predict future hair loss. The measurements will enable the physician to better estimate the size of the donor strip and anticipate the aesthetic outcome of the hair restoration procedure. This paper describes the value of these techniques in the hair transplant evaluation.
In this paper, Dr. James Harris presents a blunt tip instrument to be used in a 3-step FUE hair transplant procedure. The instrument is described as a 1-mm dissecting punch that has a tapered blunt edge. After scoring the skin with a sharp punch, the dissecting punch is advanced to a depth of approximately 4-mm.
This instrument is similar to the one recently described by Bernstein and Rassman in New Instrumentation for Three-Step Follicular Unit Extraction, recently published in Hair Transplant forum International New Instrumentation. Dr. Bernstein’s instrument was, in turn, based upon ideas presented in a paper written by Dr. Harris in 2004.
Synopsis: Three-step FUE is a hair transplant technique that uses blunt dissection to prevent damage during the process of separating the follicular unit from the surrounding tissue. The 3 steps are: scoring, blunt dissection, and extraction. Performing Follicular Unit Extraction with a 3-step technique allows the surgeon to minimize damage to follicles and to keep follicular units intact. A disadvantage is the development of buried grafts, but this can be reduced by modifying the technique and using specially designed instrumentation.
Synopsis: The partial or complete loss of one’s eyebrows is a relatively common problem and can be caused by disease, accidents, the normal aging process, or can be been self-induced. This paper discusses the importance of eyebrows to one’s appearance and explains the special techniques and surgical skills required for eyebrow restoration.

Graft Anchoring in Hair Transplantation: Summary Read More »
Synopsis: This study determined exactly how long it takes after a hair transplant for the grafts to be securely anchored in the recipient area, so that they cannot be dislodged. This information is important in guiding the patient’s post-op care after a hair restoration procedure. The study also showed that preventing the formation of crusts following a hair transplant would shorten the time patients are at risk of dislodging grafts. It would also allow them to return to their normal hair care routines more rapidly.
Synopsis: This paper discusses the state-of-the-art in follicular unit extraction. It focuses on the new Three-Step Technique in which a sharp punch is used to cut the epidermis and then a dull punch is used to dissect the follicular unit from the surrounding tissue. The third step being the extraction itself. The “blunt” step significantly reduces follicular transaction, but creates a potential new problem, that of buried grafts. The Three-Step technique increases the number of patients in whom FUE is possible; however, other limitations of the procedure – particularly the lower total yield compared to strip harvesting – remain.
Synopsis: This writing discusses the current status of Follicular Unit Transplantation and some controversial issues regarding this procedure. These issues include: strip harvesting vs. follicular unit extraction, lateral vs. vertical slit recipient sites, which holding solution is best for grafts, the ideal density and the optimal number of grafts that should be performed in one hair transplant session.

SUMMARY of Dr. Perez-Meza’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
There have been great advances in hair restoration surgery over the past decade. New surgical techniques, instruments and medications have been developed to treat patients with hair loss. Some surgeons use needles to create the recipient sites and others use blades – both groups obtaining great results. There is some controversy, however, about the “ideal” instrument to make the recipient sites.
The objective of this study was to evaluate three different blades and three different needles used to make sites in the recipient area and to compare the wound healing and hair growth after the hair transplan
SUMMARY of Dr. Beehner’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
There is a need to find the “threshold” density at which follicular unit (FU) graft recipient sites may be placed and yield excellent survival following a hair transplant. It also needs to be determined whether or not a smaller recipient site makes a difference in graft survival. This study looks at hair survival in two patients 18 months after they were each transplanted with four different densities.
The objective of the study was to determine the optimal density for “dense packing” FU grafts without causing loss of hair from vascular compromise or other factors that can affect graft growth during hair restoration surgery.
SUMMARY of Dr. Abbasi’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
Edema of forehead and peri-orbital area is observed frequently after a hair transplant. To prevent this edema the authors introduced a new method (Abassi’s solution) at the 12th Scientific Meeting of ISHRS in Vancouver, Canada. The present study tries to determine if Abbasi’s solution can have a negative effect on the growth of transplanted grafts following hair restoration surgery.
In this study, the authors examined the effects of Abbasi’s solution on hair growth one year after a hair restoration procedure.
SUMMARY of Dr. Mohmand’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
The objective of this presentation is to share our experience and observations regarding the importance of the angle of curvature of the hair shaft during the hair transplant for producing a natural looking hairline.
Four important factors were kept in mind while performing the hair transplant regarding the natural looking hairline: 1) Avoidance of a straight line, 2) Keeping a transition zone between the bare forehead and the dense packing, 3) Density, 4) The acute angle of exit from the skin, 5) The angle of curvature of the hair shaft.
In our experience, since incorporating the angle of curvature of the hair shaft, the naturalness of the hairline has improved significantly. This is especially true for the frontal hair rows and the temporal peaks.
Summary of “Trichophytic Closure of the Donor Area” which appeared in Hair Transplant Forum International July/August 2005 by Mario Marzola, MBBS Norwood Australia
When hair transplant surgeons meticulously close the edges of a donor wound, they generally end up with a fine, linear scar that is approximately 1-2mm in width. Sometimes, the scar can be a bit wider and every once in a while, when the person’s connective tissue is weak, or the edges of the scar are closed too roughly or have too much tension, the scar can be a cosmetic problem. The educated patient, who has expectations of a thin scar, or the patient who is likely to wear his hair very short, hopes that their hair transplant doctor can produce scars that are practically invisible.
A Trichophytic closure is a way of improving the linear donor scars of hair transplant patients. A Trichophytic incision in hair transplantation involves trimming off the upper edge of the incision and then closing the wound in such a way the hair near the edge can grow through the scar. This has the potential to produce a scar that is virtually undetectable.
To perform a comparison study, Dr. Marzola conducted a trial using 26 consecutive patients. Each hair transplant patient had one side of their scar closed trichophytically (i.e., with the top edge removed) and the other side closed with the edge left as is.
SUMMARY of Dr. Harris’ Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
The SAFE System for FUE provided a novel methodology and new hair transplant instrumentation to increase graft production rates, decrease follicle transection rate, and expand patient candidacy for surgical hair restoration. However, the mechanism of the interaction of the blunt dissecting punch and the dermis produced follicular unit graft burial (approximately 7.2% of attempted extractions) that slowed the extraction process during the hair transplantation and resulted in inflammatory cysts requiring surgical excision in .02% of attempted graft extractions.
The purpose of this study was to assess the efficacy of a new dissecting tip that could potentially decrease the graft burial rate and increase the graft production rate in the hair restoration. In the study, three patients received a total of 422 grafts. The protocol utilized limited sharp dissection of the epidermis (using a 1-mm punch to a depth of approximately 1.3 mm) followed by the insertion of the specially modified dull dissecting tip to its full depth of 5 mm. The follicular units were then grasped with fine forceps and removed.
SUMMARY of Dr. Haber’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia
Harvesting high quality donor strips with minimal transaction remains an elusive goal for many hair transplant surgeons, particularly beginners. Hair restoration techniques that involve the use of scalpel blades demand the greatest skill and may cause significant transection. The Sandoval Score and Spread technique showed that non-traumatic dissection during hair transplantation is possible using a blunt instrument, but this technique is limited by poor ergonomics and the potential to cause tissue damage.
A new instrument for blunt dissection had been developed that is easy to use and is able to separate tissue along the natural planes of cleavage that causes minimal damage to hair follicles. This device has four sharp, staggered prongs aligned centrally and long handles developed for hair transplant procedures. This design utilizes the strong forearm muscles, as opposed to the weaker hand muscles, and distributes the spreading force over a larger area, minimizing trauma. A minimum depth scoring incision is made with a double-bladed scalpel to a depth of 1.5 mm. The device is inserted and expanded at intervals along the incision.
Synopsis: This paper reviews the core concepts of Follicular Unit Transplantation, including basing the surgical planning on the follicular unit constant, using only individual, naturally occurring units in the transplant and accomplishing the restoration in a few number of large sessions. The section then describes the techniques of follicular unit hair transplantation as the procedure enters its second decade.

Synopsis: “Surgery of the Skin: Procedural Dermatology,” covers the entire range of dermatologic surgical procedures. It was conceived to be used as the core surgical textbook for dermatologic training programs. Dr. Bernstein’s chapter on follicular unit hair transplantation covers a wide range of subjects including the history of follicular unit hair transplantation, evaluating the patient, planning the surgery, setting-up the operating room, and maximizing the cosmetic outcome of the hair restoration. Specific topics include the techniques of Follicular Unit Transplantation including density assessment, single-strip harvesting, follicular unit extraction, anesthetic use, aesthetic design and many other important topics.
Synopsis: This writing is the textbook version of the paper; “Limiting Epinephrine in Hair Transplant Sessions.”
Synopsis: This is the textbook version of the important 1999 paper; “The Logic of Follicular Unit Transplantation” that was instrumental in making follicular unit transplantation a mainstream hair restoration procedure.
Synopsis: This paper describes the technical and organizational skills needed for performing Follicular Unit Extraction Megasessions. It also points out some of the important long-term implications of FUE, especially regarding its inefficient use of donor area which potentially limits the ultimate donor supply.
Synopsis: This paper proposes that the old punch-graft technique may have a place in modern hair transplant surgery, particularly in patients with significant donor scarring and when further linear incisions are not possible. In these cases, punch harvesting (with subsequent microscopic division of the punch grafts) may be better than FUE, since extracting individual follicular units can be difficult in areas of scarring.

SUMMARY of Dr. Bernstein’s editorial commentary on Hwang SM et al. Does the Recipient Site Influence Hair Growth Characteristics in Hair Transplantation? The original article appeared in Dermatol Surg 2002; 28(9): 798-99. The field of hair transplantation in the United States began with Dr. Norman Orentreich’s famous 1959 paper on Donor Dominance. In it, he …
Synopsis: In 1959, Orentreich stated that, in a hair transplant, the transplanted grafts maintained the characteristics of the donor area and were independent of the recipient site. However, new evidence suggests that that the recipient site can influence the rate of hair growth, graying, and the formation of wavy hair. The editor points out that, although these observed effects may violate the principle of donor dominance, they will have positive implications for the success of cloning.
Synopsis: Patients with tight scalps and snug donor closures often heal with fine scars, whereas patients with loose scalps occasionally heal with wide scars. A patient with the rare condition Ehlers-Danlos Syndrome shed light on this phenomenon. After studying his case, the authors conclude that the integrity of the scalp’s connective tissue was more important than scalp laxity in determining who would heal with a fine donor scar.
Synopsis: This paper reviews the current status and future of automated devices in surgical hair restoration. Specifically, it discusses the Hair Implanter Pen, the Rapid Fire Hair Inserter, the Calvitron, and the Choi Hair Transplanter.
Synopsis: This study compares the hair replacement techniques of mini-micrografting, vertical sectioning and single-strip harvesting with stereo-microscopic dissection for the generation of follicular unit grafts. It validated the superiority of the latter technique and supported the idea that if one wants to perform Follicular Unit Transplantation properly, single strip harvesting and microscopic dissection should be required.
Synopsis: This popular guide on hair restoration is revised to include the latest advances in medical and surgical treatments for hair loss and an expanded section of before and after photos.

A New Suture for Hair Transplantation: Poliglecaprone 25: Summary Read More »
Synopsis: This paper introduces a new synthetic suture for surgical hair restoration called Poliglecaprone 25 or Monocryl. It is a strong, absorbable, suture with low tissue reactivity that can be used in hair transplantation to close the donor wound with a single, running stitch. This suture can provide a donor closure that ensures hemostasis, has little risk of infection and is comfortable for the patient, and generally results in a fine surgical scar.
Synopsis: This editorial emphasizes that an accurate representation of a hair transplant technique is important, even if it is with respect to how it is named, so that the public may make informed decisions about the procedures they choose.
Synopsis: This editorial discusses the important observation of Gandelman that the drying of grafts during a hair transplant is a common denominator for other forms of injury, as it makes the grafts more subject to damage due to crushing and warming during the procedure.
Synopsis: The risks of using too much adrenaline in a hair transplant are discussed and a number of alternative methods of establishing hemostasis are offered including; body positioning, florescent lighting, ring-block anesthesia, tumescence, pre-making recipient sites, applying bi-manual traction, and creating a snug fit between the recipient site and graft.
Synopsis: When follicular unit transplantation was still in its infancy, there were many detractors in the hair transplant community. This paper defended the procedure and explained its superiority over other hair replacement techniques in producing the best short and long-term cosmetic results.
Follicular unit hair transplantation offers many advantages, but hair transplant surgeons continue to debate whether it is worth the effort.
A recent paper that clearly differentiates this hair transplant technique from the older technique of mini-micrografting cut to size is a step toward resolution of this controversy, while a new implanting device minimizes some of the time intensiveness of the hair transplant procedure may further popularize follicular unit transplantation, said Robert M. Bernstein, M.D.
Synopsis: This section, published in a textbook for professional estheticians, explains basic concepts of follicular unit hair transplantation in easy-to-understand terms.
Synopsis: This article uncovers an attempt by the proponents of slot grafting to rename this technique (which produces poor cosmetic results) and call it “follicular unit coupling,” so that unwary patients will think that it is actually a variation of follicular unit transplantation.
Synopsis: This short paper summarizes the article that advises to physicians to limit the use of adrenaline when performing large hair transplant sessions and it explains various practical ways to accomplish this.
Synopsis: This paper argues for standardization in the classification of various hair transplant techniques in order to facilitate communication between hair restoration surgeons and their patients and to aid in scientific research.
Synopsis: As the twentieth century drew to a close, this paper looked into the future to try to discern the direction that hair transplantation was headed in the next millennium. Particular areas of interest were; the follicular unit/mini-micrograft controversy, graft storage mediums, how to maximize the donor supply, methods to enhance wound healing, automated devices, lasers, new medications, cloning and genetic engineering.
Synopsis: This editorial cautions that new instruments made to cut the donor strip rapidly, by placing the strip on a grid of knives, cause unacceptable levels of graft damage. The author advises that these devices should not be used in surgical hair restoration.
A New Surgical Instrument For the Automation of Hair Transplantation WILLIAM R. RASSMAN, MD, Los Angeles, CA ROBERT M. BERNSTEIN, MD, New York, NY Dermatologic Surgery 1998; 24: 623-627.

Synopsis: The “Carousel” is an automated device used for hair transplantation that simultaneously makes recipient sites and inserts grafts. The instrument can hold up to 100 grafts at time. In theory, the instrument could decrease the total operative time and eliminate some human factors that contribute to graft injury during the hair restoration process. The Carousel, however, was limited in that very close graft placement was not possible and it could not account for the great variability in the human scalp that sometimes rendered the device ineffective.
Synopsis: Dr. Bernstein heads a group of twenty-one hair restoration surgeons in an attempt to standardize the classification of follicular unit transplantation and other small graft procedures, including various technical aspects of graft harvesting, graft dissection, and placement. The goal is to standardize the nomenclature, and formally describe other factors in the surgery, so that communication between physicians and patients may be enhanced and different hair replacement procedures may be examined and compared.

I just returned from visiting Dr. Bob Bernstein in New York, and was impressed with his operation and even more impressed with his thoughts, observations, and insights into hair transplant surgery. He applies scientific methods to his work, is academically honest, and has an almost eerie instinctive knowledge of hair transplant surgery. Of course he has Dr. Bill Rassman to work with, but it is still remarkable. Dr. Bernstein is best known for introducing follicular transplantation to hair transplant surgery, an idea Bob Limmer has been pushing for ten years with the use of the binocular microscope, but no one would listen to him. Dr. Limmer, however, never used the term follicular transplantation. Using the microscope, you automatically dissect the follicular units. It can’t be avoided if done properly.
Synopsis: An editorial that challenges the assumption that insufficient blood supply in a hair transplant is the main contributor to delayed growth.

Follicular Transplantation: Patient Evaluation and Surgical Planning: Summary Read More »
Synopsis: This landmark paper details how a patient should be evaluated for Follicular Unit Transplantation, stressing densitometry as a means of assessing both miniaturization and donor supply. It also provides guidelines for the planning of the first and subsequent hair transplant sessions and discusses the management of patients with diffuse androgenetic hair loss.
Synopsis: This short article describes the design for a wall-mounted placing stand that can store, chill and protect grafts while they are waiting to be placed into the scalp during the hair restoration procedure.
Synopsis: Hypothesizes the possible causes of delayed growth following a hair transplant procedure. It differentiates between physiologic factors that cause normal variations in the growth cycle and those due to graft injury that can possibly be prevented by meticulous surgical techniques.
Synopsis: A short paper that describes the cause and treatment of the occasional itching that follows a hair transplant procedure.
Synopsis: This writing explains the rationale for using large numbers of grafts in surgical hair restoration. It discusses the advantage of megasessions in conserving the donor supply, increasing patient satisfaction, and providing greater flexibility to the surgeon in sorting and distributing small grafts.
Synopsis: This was the first paper to challenge those promoting laser hair transplants and who claimed that lasers would be the future in surgical hair restoration. The publication stressed that lasers caused damage to the recipient area and could result in scarring and poor growth. It explained why lasers were, in fact, inferior to cold steel techniques in making recipient sites.
Synopsis: This publication, written when scalp reductions were at the height of their popularity, cautioned that scalp reductions caused unnecessary scarring, used up precious donor reserves and caused more cosmetic problems than they solved. It suggested that, with the advent of the more robust follicular unit hair transplantation, scalp reductions should not be used in the treatment of androgenetic hair loss. This publication, along with the 1993 paper of O’Tar Norwood, played a critical role causing the rapid decline in the use of scalp reductions in hair restoration surgery. Fortunately, this once common procedure for male pattern alopecia is now rarely used.
Synopsis: This was the first paper on Follicular Unit Transplantation. This publication introduced into the medical literature the idea of using individual, naturally occurring follicular units exclusively in the hair transplant procedure and stressed using large sessions to maximize the aesthetic outcome. The paper defined the various components of Follicular Unit Hair Transplantation, explained the anatomic and physiologic advantage of using follicular units in the procedure and described how follicular units could be used safely in large numbers to complete the hair restoration as quickly as possible. This publication was instrumental in having hair restoration surgeons shift from the older mini-micrografting techniques to the cosmetically superior technique of using follicular units.
