Q: How can I better understand how I will look after my hair transplant before I actually do the procedure? — E.M. ~ Wantagh, N.Y.
A: A key part of a hair loss evaluation is for the doctor to manage the patient’s expectations for possible benefits from both medication and surgery. The way we decide how to plan a hair transplant is through a careful history and examination, demarcating the extent of the hair transplant on the patient’s actual head and photographing it. When showing other photo results to patients, it is important to not only show before and after photos of the recipient area but also of the donor area; how the back of the head looks immediately after the procedure, at post-op intervals, and at different hair lengths. Most importantly, one should point out that every patient is different so that a picture of another person does not necessarily represent what you might achieve.
Q: How Many Hair Transplants Will I Need? — E.E., New York, N.Y.
A: The first session of a hair transplant should be designed as a stand-alone procedure with the following three goals:
Establishing a permanent frame to the face by creating, or reinforcing, the frontal hairline.
Providing coverage to the thinning, or bald, areas of the scalp with the hair transplant extending at least to the vertex transition point.
Adding sufficient density so that the result will look natural.
Achieving all of these goals will allow the first procedure to stand on its own.
Because of this, many people feel one hair transplant is sufficient.
Reasons for Second Hair Transplant
While the first session of a hair transplant is designed to stand on its own, there are several reasons why one would want a second hair transplant, such as increasing the density in a previously transplanted area; refining the hairline created in the first transplant; focusing on increased crown coverage, when appropriate; or addressing further hair loss that’s occurred after the first transplant.
Because of this last reason, addressing further hair loss, careful patient evaluation and surgical planning is needed to take into account your donor reserve and the likely extent of any future balding in the planning of your first transplant session.
Wait at least 10 to 12 months Before Getting a Second Hair Transplant
If a second transplant is warranted, patients are advised to wait at least 10 to 12 months after the first transplant before considering a second. This is because over the course of the first year, the first transplanted hairs have grown in and the progressive increase in a hair’s diameter, texture and length can markedly change the look of the hair restoration — this may influence the way a patient wants to groom his/her hair, and only after the hair has reached styling length can the patient and physician make the best aesthetic judgments regarding the placement of additional grafts.
For patients having an FUT (strip) procedure, another reason to delay a second hair transplant session for this time period is that scalp laxity will continue to improve making the donor hair easier to harvest.

Q: How many follicles can you transplant with robotic FUE compared to manual FUE? — R.V., Upper West Side, N.Y.
A: We can extract the same number of follicles robotically as we can manually.
That said, the goal of any hair transplant procedure is not to transplant as many hair follicles as possible but rather to achieve the best possible cosmetic result given your degree of hair loss and the number of hair follicles available in your donor area.
While there is no difference between robotic and manual FUE in terms of the number of follicles that each procedure can extract, robotic FUE does have the following advantages over manual FUE:
During the follicular unit extraction (or harvesting) phase of a hair transplant, there is less chance of damaging follicular units using a robot vs. a hand held device (e.g., Neograft), because the robot is more accurate. This means more grafts survive after transplant.
Robotic graft harvesting times are shorter than manual, e.g., while on average if a physician could manually extract 200-300 grafts per hour, the same physician could robotically extract up to 500-1000 grafts per hour ((Chang, H.H. Robotics, artificial intelligence, and the future of hair transplantation. Prime Dermatology, July/August 2014.)). This means a shorter procedure time for the patient.
Q: For patients who intend to keep their hair parted on the left side, do you follow any rule of making the left side more dense then the right or is it distributed evenly? — M.S., Simi Valley, C.A.
A: On a first hair transplant procedure, I generally place the sites/grafts symmetrically, even if a patient combs his hair to one side. The reason is that the person may change his styling after the procedure and I like to have the first hair transplant symmetrical for maximum flexibility. An exception would be a person with limited donor reserves. In this case, weighting on the part side is appropriate in the first procedure. Once the first hair transplant grows in and the person decides how he wants to wear his hair long-term a second transplant can be weighted to accommodate this. Weighting can be done in one, or both, of two ways: 1) by placing the sites closer together on the part side or 2) by placing slightly larger follicular units on the part side.
If a person decides to comb his hair back, then forward weighting is used. For greater details on this, please see some of my publications where I address the aesthetics of hair transplantation:
Dr. Bernstein is credited with introducing the “follicular unit” to surgical hair restoration, the innovation that allowed for a “completely natural-looking hair transplant” to be achieved. The commentary on Dr. Bernstein’s contributions to the field of hair transplantation are outlined in an historical review of dermatologic surgery that appeared in the Journal of the American Academy of Dermatology.
Dr. Bernstein is noted as being responsible for moving the field of hair restoration surgery away from large graft “plugs” and mini-micrografts to follicular units:
The 2 advances, the application of the stereomicroscope to follicular dissection and the use of follicular units as the basic element of hair transplantation, arose from a background in dermatology. They moved the field of hair restoration surgery from plugs and mini-micrografting, where this basic anatomical feature of the hair follicle was ignored, to follicular unit transplantation, where the follicular unit became sacrosanct. These 2 ideas, when put to clinical use, allowed the once elusive goal of a completely natural-looking hair transplant to finally be achieved.
Dr. Bernstein’s pioneering of the Follicular Unit Transplant (FUT) procedure still resonates, almost two decades later, as the follicular unit continues to be the anatomical structure that is transplanted in hair transplant surgeries worldwide.
The article then describes how Dr. Bernstein, along with his colleague Dr. Rassman, laid the foundation for the next major developments in hair restoration; first with his description of the Follicular Unit Extraction (FUE) technique and more recently with innovation in robotic hair restoration technology.
With the publication of the article, “Follicular unit extraction,” in 2002, the follicular unit extraction procedure gained popular appeal and was rapidly adopted by doctors worldwide. The authors cautioned on the limitations of this harvesting technique and the risk of follicular damage. Dermatologists Berman, Zering, and Bernstein, along with their colleagues in other specialties, continue to work on the problem of harvesting in follicular unit extraction, with the application of robotic technology showing particular promise.”
Taken together, these passages underscore how Dr. Bernstein’s research and medical publications have fundamentally transformed the field of hair restoration to the benefit of patients and physicians alike. While many other very talented physicians have had a substantial impact on hair restoration procedures ever since the hair transplant concept was first proposed by Dr. Norman Orentreich in the 1950s, Dr. Bernstein has contributed the key innovations that have made modern, natural-looking hair transplant surgery a medical and aesthetic possibility.
The article is titled, “Current status of surgery in dermatology.” The Journal of the American Academy of Dermatology is the official journal of The American Academy of Dermatology (AAD), the largest, most influential and most representative dermatology group in the United States.

The 21st Annual Scientific Meeting of the International Society of Hair Restoration Surgery was held in San Francisco from October 13 through 26, 2013. The meeting covers the most important scientific and clinical advances in the field of surgical hair restoration.
As a member of the panel on “Difficult Cases,” that explored challenging and atypical medical conditions and their treatment, Dr. Bernstein presented the “Management of Frontal Fibrosing Alopecia.” This condition is a form of primary scarring hair loss. Dr. Bernstein chose to discuss this disease because it can be mistaken for common baldness; however, since the transplanted hair will be destroyed by the disease process, it is a contra-indication for hair transplantation. Since missing this diagnosis can lead to unnecessary and ineffectual surgery, an awareness of its signs and symptoms are important for every physician managing patients with hair loss.
On the panel on “Post Finasteride Syndrome,” Dr. Bernstein was part of a group that reviewed the latest studies on the efficacy and safety of finasteride in the treatment of androgenetic alopecia. They discussed possible adverse events including claims of persistent sexual dysfunction (Post Finasteride Syndrome) and concerns relating to prostate cancer. They also discussed the challenges that arise in caring for patients when scientific research and the mass media give conflicting information.
In the Symposium “Question the Expert,” Dr. Bernstein presented a case of Diffuse Un-patterned alopeica (DUPA). This condition was first detailed by Dr. Bernstein in his landmark paper “Follicular Transplantation: Patient Evaluation and Surgical Planning,” that was published in Dermatologic Surgery in 1997. DUPA is a form of androgenetic alopecia that presents as rapid generalized hair loss in young adults. Besides being a significant psychological burden for young men and women, its identification is extremely important since medical intervention can have a significant positive impact when instituted early. On the other hand, a misdiagnosis that leads to surgery can result in a failed hair transplant and donor scarring that may become visible over time.
Dr. Bernstein was also the Keynote Speaker for the ARTAS International Users Forum. His presentation, titled “Follicular Unit Extraction: Then and Now,” discussed the evolution of FUT, FUE and Robotic-FUE and how it relates to today’s hair restoration practice. Of particular significance was the natural progression of FUE instrumentation from hand-held manual tools to robotic assisted hair transplantation. Dr. Bernstein explained that in the future, robotic capabilities will not be limited to graft extraction, but eventually will perform each aspect of the transplant including recipient site creation, and graft placement. See “Dr. Bernstein Gives Keynote Presentation On Robotic Hair Transplantation” for more details on the presentation and some photographs of the event.
Q: What is the Origin of the Term DUPA? — Z.Z., Darien, CT
A: The terms DPA and DUPA were first described by O’tar Norwood in his seminal 1975 publication: Male Pattern Baldness: Classification and Incidence. ((Norwood OT. Male pattern baldness: classification and incidence. So. Med. J 1975;68:1359-1365. Download)) In the paper, Dr. Norwood defined the two terms as:
Diffuse, Unpatterned Alopecia (DUPA). In this type there is a general decrease in the density of hair without any definite pattern, although it is usually more marked over the top and front. This type is common in women.
Diffuse, Patterned Alopecia (DPA). The patterns in this type of hair loss are essentially the same as in more common male pattern baldness, but the areas involved do not become totally bald; the hair only decreases in density. This also occurs in women.
Dr. Norwood’s realization that all hair loss did NOT follow his own Norwood patterns was a great insight, as well as his observation that DUPA was a common pattern in women and uncommon in men. The terms went relatively unnoticed and were not seen again in the medical literature until Drs. Bernstein and Rassman wrote about them again when they were developing Follicular Unit Transplantation. ((Bernstein RM, Rassman WR: Follicular Transplantation: Patient Evaluation and Surgical Planning. Dermatol Surg 1997; 23: 771-84. Download)) The importance of identifying these conditions is that that DUPA (either in men or women) is a relative contra-indication for hair transplantation and, with densitometry, can be readily detected in individuals at a relatively young age. Patients with DPA can be transplanted as if they were early Norwood Class 6’s.
Q: Can the crown be transplanted first instead of frontal area? Why is the crown the last choice? Any reasons behind it? — H.H., Ladue, M.I.
A: The crown can be transplanted first in patients who have very good donor reserves (i.e., high density and good scalp laxity). Otherwise, after a hair restoration procedure to the crown you may not be left with enough hair to complete the front and top if those areas were to bald.
Cosmetically, the front and top are much more important to restore than the back. A careful examination by a trained hair restoration surgeon can tell how much donor hair there is available for a hair transplant.
Q: I am 19 years old and seem to be thinning all over, including the sides. My father has all of his hair but my grandfather is totally bald. Should I have a hair transplant now or wait until I am older? — T.K., Garden City, NY
A: Most likely you have a type of androgenetic alopecia called Diffuse Unpatterned Alopecia (DUPA). In this hereditary condition, hair thins all over rather than just on the front, top and back as in the more common male pattern baldness. The fact that the back and sides of your scalp are thinning (the donor area) precludes you from being a candidate for surgery. The diagnosis can be made by observing a high degree of miniaturization (fine hair) in the donor area under a magnifier. This instrument is called a densitometer.
Q: Should you perform a hair transplant on a crown that is just starting to thin? — R.R. Philadelphia, Pennsylvania
A: A “thin” crown should first be treated with Propecia, as it may thicken the hair to a cosmetically acceptable degree without the need for surgery. If Propecia is ineffective in restoring enough hair, then surgical hair restoration can be considered.
The surgeon must also factor whether or not the patient has enough donor reserves to transplant the front and top part of the scalp if the patient becomes very bald. This is hard to predict in patients who are still in their twenties.
Q: If my hair is just starting to thin, when should I have my first hair transplant? — T.O., Bayonne, NJ
A: It is best to wait until at least 25 before considering hair transplant surgery, although there are exceptions. The most important thing is to wait until you have hair loss that is a cosmetic problem. A hair transplant is a treatment for hair loss — it should not be used as a prevention. When hair loss is just starting, medical therapy is generally a better choice than surgery as it can both regrow hair and prevent future loss.
