Hair Restoration Publications & FUE Research |
Kenneth L. Williams Jr., DO, ABHRS, FISHRS
Dr. Kenneth L. Williams Jr. has contributed to the medical literature and professional education of hair restoration physicians through peer-reviewed journal articles, medical textbooks, clinical research, and scientific presentations.
FUE Research
Dr. Williams Published Work on FUE Safety
His published work has focused particularly on Follicular Unit Excision (FUE), donor-area safety, complications of hair transplant surgery, surgical instrumentation, physician responsibility in hair restoration surgery, nonsurgical hair-loss treatment, and the physical demands associated with performing hair transplant procedures.
Rather than approaching hair restoration exclusively from the perspective of clinical practice, Dr. Williams has participated in the study, publication, and professional teaching of many of the same surgical issues he encounters in patient care.
His academic work is especially concentrated around one question central to modern FUE surgery:
How can hair be harvested effectively while preserving the patient’s limited donor area and reducing avoidable complications?
Areas of Published Expertise
Dr. Williams’ professional literature and textbook contributions support several interconnected areas of expertise.
These include Follicular Unit Excision (FUE), donor-area management, donor-site injury, FUE complications, overharvesting, punch design and instrumentation, FUE versus FUT decision-making, physician oversight of hair transplant surgery, nonsurgical hair-loss treatment, and ergonomics in hair restoration surgery.
This body of work complements his clinical experience and his professional roles educating and examining other physicians in hair restoration surgery.
Peer Reviewed Publications
Complications with Follicular Unit Excision
Kenneth L. Williams Jr., DO; Shady El-Maghraby
Facial Plastic Surgery
2024; 40(2):234–244
DOI: 10.1055/a-2201-8302
PMID: 37907286
What the publication examined
Follicular Unit Excision is often described primarily in terms of its advantages. This publication examines FUE complications- temporary and permanent complications that may occur when FUE is performed improperly or when surgical planning, technique, or patient selection is inadequate.
The article addresses the technical demands of FUE harvesting and discusses complications affecting both the donor and recipient areas.
Why this work is important
FUE removes individual follicular units from a finite donor supply. Poor extraction planning or technique can therefore affect not only the appearance of the donor region but also the patient’s future options for hair restoration.
Understanding complications is particularly relevant when evaluating donor overharvesting, visible donor thinning, scarring, graft damage, and patients seeking corrective hair transplant surgery.
Dr. Williams’ authorship of this publication directly supports his professional focus on FUE complications, donor management, and corrective hair restoration.

Current Practices and Controversies in Cosmetic Hair Restoration
Ken L. Williams Jr., DO
Dermatologic Surgery
2013; 39(5):797–801
DOI: 10.1111/dsu.12163
PMID: 23464750
What the publication examined
This article reviewed the development of modern hair restoration surgery, the emergence of Follicular Unit Extraction (as it was defined), and differences between FUE and Follicular Unit Transplantation, and controversies surrounding the adoption and marketing of FUE technology.
The paper also discussed physician responsibility and concerns regarding the delegation of surgical care to unlicensed personnel.
Why this work remains relevant
Technology has changed considerably since the article was published, but the underlying issue remains important.
A hair transplant device does not replace medical judgment, surgical planning, donor assessment, or physician responsibility.
The publication demonstrates that Dr. Williams’ interest in FUE has extended beyond performing the technique itself. His professional work has also examined how FUE is practiced, who should perform surgical steps, how patients should be protected, and how emerging technology should be incorporated responsibly into surgical care.

Minimizing Injury to the Donor Area in Follicular Unit Extraction (FUE) Harvesting
Georgios Zontos, MD, BSc, MS, PhD; Ken L. Williams Jr., DO; George Nikiforidis, PhD
Journal of Cosmetic Dermatology
2017; 16(1):61–69
First published online August 24, 2016
DOI: 10.1111/jocd.12267
PMID: 27557792
What the study examined
This study investigated injury created in the donor area during FUE harvesting.
Thirty-five patients were evaluated using two extraction approaches, with researchers examining differences in wound surface area and the amount of skin tissue removed during harvesting.
The study reported significantly lower mean wound surface area and skin mass in the technique involving intradermal saline before extraction.
Why this work is important
Every follicular extraction creates a small wound within the donor area. This is referred to as a “punctate” lesion that is composed of scar tissue.
The individual extraction wounds only are observed when the hair is cut to a number one length. When the hair is longer, the scar tissue is not observed, but the extraction scars and wounds are produced during a typical FUE procedure. The cumulative effect of those extractions makes punch selection, extraction technique, spacing, density, and donor planning clinically important.
This research directly supports one of the central principles of Dr. Williams’ approach to FUE:
The goal of donor harvesting is not simply to obtain grafts. It is to obtain intact follicles or grafts while preserving the appearance, density, and long-term value of the donor area.
The study was published in the Journal of Cosmetic Dermatology. Review the paper here.
The Shifting Preferences of Patients and Physicians in Nonsurgical Hair Loss Treatment
Aditya K. Gupta, MD, PhD; Emma M. Quinlan; Ken L. Williams, DO
Journal of Cosmetic Dermatology
2021; 20(3):929–936
DOI: 10.1111/jocd.13681
PMID: 32892459
What the study examined
This study evaluated changes in patient and physician interest in nonsurgical hair-loss therapies.
The authors compared worldwide Google search trends with physician prescribing patterns reported by members of the International Society of Hair Restoration Surgery.
Treatments evaluated included established pharmaceutical therapies as well as other commonly discussed nonsurgical approaches.
Why this work is relevant to patient care
Not every patient experiencing hair loss is an appropriate candidate for surgery.
Determining the cause of hair loss and understanding available medical and nonsurgical treatments are important parts of developing an appropriate long-term treatment plan.
The publication also illustrates an important distinction between what patients search for and what physicians actually recommend.
Dr. Williams’ contribution to this research supports a broader approach to hair restoration in which surgical and nonsurgical options are considered within the context of the patient’s diagnosis, pattern of loss, age, available donor hair, and anticipated progression.

The Ergonomics in Hair Restoration Surgery
Ken L. Williams Jr., DO; Aditya K. Gupta, MD, PhD; Hayden Schultz
Journal of Cosmetic Dermatology
2016; 15(1):66–71
DOI: 10.1111/jocd.12188
PMID: 26440582
What the study examined
Hair restoration surgery often requires physicians to perform repetitive, visually demanding procedures for extended periods.
This study surveyed hair restoration surgeons regarding work-related musculoskeletal symptoms associated with performing hair transplant procedures.
Half of the responding surgeons reported musculoskeletal symptoms during or following hair restoration procedures, with pain reported more frequently in connection with FUE than with strip excision procedures.
Why this research matters
The study examines a less obvious aspect of FUE surgery: the demands placed on the surgeon performing repeated follicular-unit extraction.
FUE requires prolonged concentration, repetitive hand movements, visual precision, posture control, hand-eye coordination, and physical endurance.
These factors are relevant not only to physician health but also to understanding the technical nature of performing large numbers of individual extractions consistently.
Dr. Williams has subsequently lectured to other hair restoration physicians on ergonomics and the musculoskeletal consequences of hair transplant surgery.
The paper is indexed by PubMed and was published in the Journal of Cosmetic Dermatology.
Biocellular Regenerative Therapy in Hair Loss
Dr. Williams has also participated in registered clinical research examining regenerative approaches to androgenetic alopecia and female pattern hair loss.
ClinicalTrials.gov identifies Kenneth Williams, DO as the Principal Investigator associated with the Irvine location for:
Biocellular Regenerative Therapy in Hair Loss: Use of High Density Platelet-Rich Plasma Concentrates and Cell-Enriched Emulsified Adipose-Derived Tissue Stromal Vascular Fraction
ClinicalTrials.gov Identifier: NCT02849470
Study ID: GARM 6.1.16
The proposed investigation was designed to study combinations involving high-density platelet-rich plasma and adipose-derived tissue/cellular preparations for hair loss.
ClinicalTrials.gov currently lists the study as withdrawn, with enrollment of zero participants. The registry states that the study was terminated before patient enrollment and cites complications related to COVID and recruitment of qualified candidates.
This distinction is important.
Registration or participation in clinical research does not establish that an investigational therapy is effective. The study should therefore be considered part of Dr. Williams’ research history rather than evidence supporting the effectiveness of the investigated treatment.
The record does, however, independently document his role in research examining emerging biological approaches to hair loss.
Medical Textbooks and Professional Reference Works
Hair Transplant 360: Follicular Unit Excision (FUE)
Editors: Kenneth L. Williams Jr., DO and Samuel M. Lam, MD
Dr. Williams is co-editor of Hair Transplant 360: Follicular Unit Excision (FUE), a professional medical textbook devoted specifically to FUE hair transplantation.
The first edition was published in 2016, and the second edition was released in 2022.
The substantially expanded second edition was published by Jaypee Brothers Medical Publishers in 2022. The second edition contains 60 chapters across two hardcover volumes and covers subjects ranging from basic FUE principles and operative fundamentals to devices, donor management, complications, repair techniques, and advanced surgical approaches.
The textbook is intended primarily as a professional educational resource for physicians and surgical teams rather than as a patient guide.
Dr. Williams’ role as co-editor is particularly relevant to his FUE authority because editing a multi-author medical reference requires organizing and evaluating contributions across a broad range of topics within the procedure.
These topics include instrumentation, donor harvesting, patient selection, complications, repair, graft handling, surgical technique, and clinical decision-making.
The 2022 edition is independently listed by its medical publisher with Kenneth L. Williams Jr. and Samuel M. Lam as editors.
Publisher: Jaypee Brothers Medical Publishers
Second Edition: 2022
ISBN: 9789354652011
From Medical Literature to Clinical Decision-Making
Scientific publication does not mean that every patient should receive the technique, medication, or procedure being studied.
Research is most valuable when it improves the questions physicians ask before treatment.
In hair restoration surgery, those questions include:
Is the patient’s diagnosis appropriate for surgery?
How much donor hair can safely be harvested?
Which donor-harvesting method is most appropriate?
How can donor-area injury be minimized?
How should grafts be extracted without unnecessarily damaging surrounding tissue?
What factors increase the risk of overharvesting or visible donor thinning?
When should FUE be used instead of FUT?
What complications should the surgeon anticipate?
Can a previous hair transplant be safely repaired?
Why is medical treatment important for hair loss if surgery is being considered?
These are recurring themes throughout Dr. Williams’ clinical work, publications, textbooks, and physician education.
His research record therefore serves a practical purpose: helping inform the evaluation, planning, and performance of hair restoration treatment.
Considering Hair Restoration Surgery?
Published research and professional credentials are useful when evaluating a surgeon, but treatment recommendations ultimately depend on the individual patient.
A hair restoration consultation with Dr. Williams includes evaluation of the pattern and cause of hair loss, donor-area characteristics, treatment history, future hair-loss risk, and whether surgical or nonsurgical treatment is appropriate.
For patients considering FUE, particular attention is given to the long-term preservation and responsible use of the donor area.
