The following is a list of Dr. Bernstein's medical publications on Follicular Unit Transplantation, Follicular Unit Extraction, Robotic Hair Transplants, and other hair restoration topics. The publications are listed from the most recent down to the first publications.
  1. The Notable Articles Project: Revisiting the Articles That Helped Shape the Specialty

    Synopsis: The traditional order for the steps of a hair transplant sur­ gery has been to first perform donor harvesting then make sites and place grafts. Hair transplant surgery can often be a long procedure, and one goal of many teams is to find ways to decrease the length of the procedure to improve the patient experience, decrease the physical strain on the team, and specifically decrease the out-of-body time of the grafts to improve graft survival.

  2. Innovations In Robotic Hair Restoration
    Bernstein RM, Wolfeld MB

    Synopsis: With the latest version of the ARTAS platform, 9x, Restoration Robotics has designed a faster and more accurate system for hair transplantation. The improved accuracy of harvesting and shortened procedure time increases graft viability, while smaller needles reduce scarring and allow patients to wear shorter hairstyles. Many of the changes in this upgrade have been made as a response to specific physician feedback.

  3. Advances in Robotic FUE
    Bernstein RM, Wolfeld MB

    Synopsis: Since the publication of “What’s New in Robotic Hair Transplantation” (Hair Transplant Forum Int’l. 2017; 27(3):100-101), there have been important improvements to the robotic system in both its incision and recipient site creation capabilities. These advances fall into four overlapping categories:increased speed, increased accuracy, increased functionality, and improved artificial intelligence (AI). The overlap occurs since improvements in functionality, accuracy, and AI can also increase the overall speed of the procedure. A faster procedure decreases the time grafts are outside the body and allows the physician to perform larger cases without placing additional oxidative stress on the follicles.

  4. Commentary on Redefining the “E” in FUE: Excision = Incision + Extraction
    Bernstein RM, Rassman WR

    Synopsis:There has been a change in the nomenclature of the FUE procedure. It will not be called Follicular Unit Excision, describing the two main components of an FUE procedure, incision (separatioin of the follicle from the tissue) and extraction (the removal of the follicular unit from the scalp once it is separated). Drs. Robert M. Bernstein and William R. Rassman’s commentary explains the importance of this change in terminology.

  5. Innovation and Quality in Hair Restoration Surgery
    Bernstein RM. Innovation and Quality in Hair Restoration Surgery. Hair Transplant Forum Intl. 2017; 27(5): 187.

    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.

  6. What’s New in Robotic Hair Transplantation
    Bernstein RM, Wolfeld MB, Krejci J. What’s New in Robotic Hair Transplantation. Hair Transplant Forum Intl. 2017; 27(3): 100:101.

    Synopsis: Since the introduction of robotic FUE technology over five years ago, there have been numerous upgrades to the system. The current paper describes the most recent advances. These include a more user-friendly interface, the ability to select for larger follicular units, greater range-of-motion of the robotic arm, improved methods for stabilizing the scalp and newly designed needles for more accurate harvesting.

  7. Robotic Follicular Unit Graft Selection
    Bernstein RM, Wolfeld MB: Robotic follicular unit graft selection. Dermatologic Surgery 2016; 42(6): 710-14.

    Synopsis: The current robotic system harvests follicular unit grafts in a random manner. A new capability of the ARTAS robot is to select follicular units based on the number of hairs they contain, in order to increase the hair/wound yield. This bilateral controlled study of 24 patients was designed to evaluate this functionality. Results showed that, compared to random follicular unit harvesting, robotic follicular unit graft selection produced more hairs per harvest attempt (2.60 vs. 2.22) and more hairs per graft (2.72 vs. 2.44). The clinical benefit was statistically significant at p<.01.

  8. Follicular Unit Hair Transplantation
    Bernstein RM, Follicular Unit Hair Transplantation. In: Robinson JK, Hanke CW, Siegel DM, Fratila A, editors: Surgery of the Skin: Procedural Dermatology, Chapter 30. Mosby Elsevier Inc., London UK. 2015: 503-533.

    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.

  9. Long-Hair Robotic FUE
    Bernstein RM. Long-Hair Robotic FUE. Restoration Robotics White Paper. May 2015.

    Synopsis: A limitation of FUE procedures is the short-term cosmetic problem of clipping the entire donor area in the back and sides of the scalp. The long-hair robotic technique avoids this problem by harvesting through a broad band of clipped hair that is covered with longer hair combed down over the harvested area. This technique enables the physician to harvest relatively large amounts of donor hair without shaving the patient’s entire scalp.

  10. Commentary on Robotic FUE in Hair Transplantation
    Bernstein RM: Commentary on Robotic Follicular Unit Extraction in Hair Transplantation. Dermatol Surg 2015;41(2):279.

    Synopsis: In their excellent article, “Robotic Follicular Unit Extraction in Hair Transplantation,” Avram and Watkin give a review of the salient aspects of the newly evolving field of robotic hair transplantation. As the authors state, the appeal of robotic FUE is part of the “inexorable trend” toward minimally invasive surgical procedures. As with any new technology, it is up to the practicing physician to make sure that it is used appropriately and to the maximum benefit of our patients.

  11. ARTAS Robotic System Provides Minimized Donor Area Scarring
    Bernstein RM. ARTAS Robotic System provides a comprehensive suite of tools to minimize donor area scarring following hair transplantation. Restoration Robotics White Paper. September 2014.

    Synopsis: The ARTAS® Robotic System provides a unique, comprehensive suite of tools that physicians can use to minimize donor area scarring and offer the patient greater styling options post-surgery. Factors that influence scarring in the donor area include: dissection punch size, density of harvest sites, distribution of the harvest sites, total number of sites, and the ‘blending in’ of harvest zones with un-harvested areas.

  12. Robotic Recipient Site Creation in Hair Transplantation
    Bernstein RM, Wolfeld MB, Zingaretti G. Robotic recipient site creation in hair transplantation. Hair Transplant Forum Intl. 2014; 24(3): 95-97.

    Synopsis: The initial application of the ARTAS® robotic system (robot), released in the fall of 2011, was the separation of follicular units from the surrounding scalp tissue, the first step in a follicular unit extraction procedure. Subsequent steps in FUE include removal of the follicular unit grafts from the donor scalp, site creation, and graft placement. With its new hardware and software capabilities, the robot can now perform one more step in this process, making recipient sites. Preliminary observations suggest that it can accomplish this function with greater precision and consistency than when performed manually.

  13. Age and the Donor Zone in FU Hair Transplants
    Bernstein RM. Controversies: Age and the donor zone in FU hair transplants. Hair Transplant Forum International 2013; 23(3): 91-92.

    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.

  14. Robotic Hair Transplants
    Bernstein RM. Robotic Hair Transplants. The Link 2013; 5: 6-7.

    Synopsis: A major advance in Follicular Unit Extraction is the introduction of a robotically controlled, image guided system to remove intact follicular units directly from the scalp. The robotic device increases the accuracy of graft harvesting, which in turn minimizes damage to hair follicles and reduces harvesting time. Each of these factors potentially contributes to increased graft survival. The technology also enables FUE to be performed on a wider variety of patients. This paper discusses this new robotic technology.

  15. Integrating Robotic FUE into a Hair Transplant Practice
    Bernstein RM. Integrating Robotic FUE into a hair transplant practice. Hair Transplant Forum Intl. 2012; 22(6): 228-229.

    Synopsis: In addition to acquiring a robotic device, performing FUE hair transplant procedures using a robotic image-guided system requires special surgical facilities, staff training, and modification of the FUE procedure itself. This paper reviews some of the key elements that go into successful implementation of R-FUE into a physician’s practice.

  16. Pre-Making Recipient Sites in FUE and R-FUE Procedures
    Bernstein RM, Rassman WR. Pre-making recipient sites to increase graft survival in manual and robotic FUE procedures. Hair Transplant Forum Intl. 2012; 22(4): 128-130.

    Synopsis: In FUT procedures, once the donor strip is removed, follicular unit dissection and graft insertion can be performed simultaneously. In FUE procedures, graft extraction must be completed before placement can begin, increasing the time grafts are out of the body and subjecting them to hypoxic injury. Waiting for recipient sites to be made adds to this time. These authors suggest creating recipient sites prior to extraction to decrease the time the grafts are outside the body. Other potential advantages of pre-making recipient sites are discussed.

  17. Bimatoprost for the Treatment of Thinning Eyebrows
    Schweiger ES, Pinchover L, Bernstein RM. Topical Bimatoprost for the Treatment of Eyebrow Hypotrichosis. J Drugs Dermatol. 2012;11(1): 106-108.

    Synopsis: Topical bimatoprost was FDA approved in December 2008 for the treatment of eyelash hypotrichosis (thinning eyelashes). Since its approval, there has been interest in its “off label” for hair growth in other areas, such as the scalp or eyebrows, but there has yet to be published scientific evidence to support this use. We report one of the first cases of significant eyebrow hair growth in a patient after use of topical bimatoprost for eyebrow hypotrichosis.

  24. Avoiding Pitfalls in Planning a Hair Transplant
    Bernstein RM: Avoiding pitfalls in planning a hair transplant. Expert Rev. Dermatol. 2008; 3(4): 501-508.

    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.

  25. Staples Revisited: Surgical Staples in Hair Transplantation
    Bernstein RM: Staples Revisited. Hair Transplant Forum International 2008; 18(1): 10-11.

    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.

  26. Follicular Unit Plain Speak: Hair Transplant Terminology
    Bernstein RM, Rassman WR, Limmer B, Follicular Unit Plain Speak. Hair Transplant Forum International 2007; 17(6): 201-203.

    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.

  27. Densitometry and Video-Microscopy
    Bernstein RM, Rassman WR: Densitometry and Video-microscopy. Hair Transplant Forum International 2007; 17(2): 41, 49-51.

    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.

  28. New Instrumentation for 3-step Follicular Unit Extraction
    Bernstein RM, Rassman WR: New Instrumentation for Three-Step Follicular Unit Extraction. Hair Transplant Forum International 2006; 16(1): 229, 237-9.

    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.

  29. Eyebrow Transplants: From Scalp to Brow
    Rassman WR, Bernstein RM: From Scalp to Brow. Plastic Surgery Products 2006; 34-8.

    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.

  30. Graft Anchoring in Hair Transplantation
    Bernstein RM, Rassman WR: Graft anchoring in hair transplantation. Dermatol Surg 2006; 32: 198-204.

    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.

  31. Follicular Unit Extraction
    Rassman WR, Harris J, Bernstein RM: Follicular Unit Extraction. In: Haber RS, Stough DB, editors: Hair Transplantation, Chapter 17. Elsevier Saunders, 2006: 133-137.

    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.

  32. Follicular Unit Transplantation
    Bernstein RM, Rassman WR: Follicular Unit Transplantation. In: Haber RS, Stough DB, editors: Hair Transplantation, Chapter 12. Elsevier Saunders, 2006: 91-97.

    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.

    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.

  39. Back to the Future with the “Dissected–Punch” Technique
    Rassman WR, Bernstein RM, Jones RG, McClellan RE, et. Al. Back to the future with the “dissected–punch” technique. Hair Transplant Forum International 2003; 13(5): 409.

    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.

  40. Follicular Unit Extraction: Minimally Invasive Surgery for Hair Transplantation

  43. Donor Dominance Revisited
    Bernstein RM: Editorial Commentary: Donor Dominance Revisited. Editorial Commentary on Hwang SM et al. Does the Recipient Site Influence Hair Growth Characteristics in Hair Transplantation? Dermatol Surg 2002; 28(9): 798-99.

    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.

  44. Scalp Laxity Paradox
    Bernstein RM, Rassman WR: The scalp laxity paradox. Hair Transplant Forum International 2002; 12(1): 9-10.

    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.

  45. Automation of Hair Transplantation
    Rassman WR, Bernstein RM: The Automation of Hair Transplantation: Past, Present, and Future. In: Harahap M, ed. Innovative Techniques in Skin Surgery. New York, Marcel Dekker, Inc., 2002: 489-502.

  49. Importance of Accurate Nomenclature
    Bernstein RM: What’s in a name? Hair Transplant Forum International 2000; 10(2): 59.

    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.

  50. Graft Injury from Dehydration: H2O and the X-factor
    Bernstein RM: Commentary: H2O and the X-factor. Editorial Commentary on Gandelman M, et al: Light and electron microscopic analysis of controlled injury to follicular unit grafts. Dermatol Surg 2000; 26(1): 31.

    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.

  51. Limiting Epinephrine in Large Hair Transplant Sessions
    Bernstein RM, Rassman WR: Limiting epinephrine in large hair transplant sessions. Hair Transplant Forum International 2000; 10(2): 39-42.

    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.

  52. In Support of Follicular Unit Transplantation
    Bernstein RM, Rassman WR, Stough D: In support of follicular unit transplantation. Dermatologic Surgery 2000; 26(2): 160-2.

    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.

  53. Hair Transplantation – Section in Textbook for Estheticians
    Bernstein RM, Rassman WR: Hair Transplantation. In: Gerson J, editor: Milady’s Standard Textbook for Professional Estheticians, 8th Ed. New York, Delmar Publishers, 1999.

    Synopsis: This section, published in a textbook for professional estheticians, explains basic concepts of follicular unit hair transplantation in easy-to-understand terms.

  54. A Slot By Any Other Name
    Bernstein RM: A slot by any other name. Hair Transplant Forum International 1999; 9(6): 175.

    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.

  55. Hemostasis with Minimal Epinephrine
    Bernstein RM, Rassman WR: Hemostasis with minimal epinephrine. Hair Transplant Forum International 1999; 9(5): 153.

    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.

  56. Unified Terminology for Hair Transplantation
    Bernstein RM: Unified terminology for hair transplantation. Hair Transplant Forum International 1999; 9(4): 121-3.

    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.

  57. Logic of Follicular Unit Transplantation
    Bernstein RM, Rassman WR: The logic of follicular unit transplantation. Dermatologic Clinics 1999; 17 (2): 277-95.

    Synopsis: This paper discusses the evolution and rationale for follicular unit hair transplantation, as well as the logic for the various techniques used in its implementation. The central role of the follicular unit constant in the surgical planning is discussed, as well as the importance of keeping recipient sites small, using microscopic dissection and performing large hair transplant sessions.

  58. Future in Hair Transplantation
    Bernstein RM, Rassman WR, Seager D, Unger WP, et al. The future in hair transplantation. Journal of Aesthetic Dermatology and Cosmetic Dermatologic Surgery 1999; 1(1): 55-89.

    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.

  59. Blind Graft Production: Value at What Cost?
    Bernstein RM: Blind graft production: Value at what cost? Hair Transplant Forum International 1998; 8(6): 28-29.

    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.

  60. Rapid Fire Hair Implanter Carousel
    Rassman WR, Bernstein RM. Rapid Fire Hair Implanter Carousel: A new surgical instrument for the automation of hair transplantation. Dermatol Surg 1998; 24: 623-7.

    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.

  77. Laser Hair Transplantation: Is It Really State-of-the-Art?
    Bernstein RM, Rassman WR: Laser hair transplantation: Is it really state of the art? Lasers in Surgery and Medicine 1996; 19: 233-5.

    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.

  78. Are Scalp Reductions Still Indicated?
    Bernstein RM: Are scalp reductions still indicated? Hair Transplant Forum Intl. 1996; 6(3): 12-13.

    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.

  79. Follicular Transplantation
