Lots of other items of interest in there besides the big three presentations that I outlined earlier.
Shiseido’s Dr. Jiro Kishimoto’s presentation seems to include results of their earlier clinical study and is titled:
“Autologous Cell-Based Therapy for Male and Female Pattern Hair Loss using Dermal Sheath Cup Cells.”
Dr. Young Sil Kim from South Korea will make an interesting presentation related to his study on ADSC and hair growth from May 2020.
“The application of the ADSC‐CE topical solution has enormous potential for hair regrowth in patients with AGA.”
A few other presentations entail using fat cells (microfat and nanofat) for hair growth.
The most unusual title award goes to: “Hair Follicle Stem Cells Activation with Polylactic Co Caprolactone Based Subdermal Implants in Androgenetic Alopecia.” — Dr. Salome Vadachkoria from Georgia.

28th ISHRS World Congress
I have covered the annual ISHRS Congress ever since starting this blog in 2013. The International Society of Hair Restoration Surgery (ISHRS) used to call these annual gatherings “Meetings” rather than “Congresses”.
The 28th ISHRS World Congress will run from October 17th, 2020 through October 25th, 2020. The ISHRS Instagram has more details. Due to Covid-19, this year’s conference is virtual (online). When I first heard this news, I was not expecting much at all.
However, the unforeseen bonus for us is that the ISHRS is already releasing very good content almost daily on its Youtube channel. In the past, we never got any decent content before the beginning of these meetings. Moreover, videos from the conferences were not even published online after the fact.
For several of the World Congress for Hair Research Events, people even crowdfunded “Scientific Event Horizon” to attend and film some of the sessions. I even donated one time when he went to Asia. I am grateful to him for delivering us the great content and learning how to film while on-site. Also a special thanks to “Hello User“.
Christiano, Plikus and Terskikh
The leading speakers are all well known to blog readers. Especially the 1st and 3rd below.
Dr. Angela Christiano — “Hair Follicle Bioengineering Producing Human Hair Follicles In Vitro Using 3D Printing Technology”.
Dr. Alexey Terskikh — “Hair Regeneration: Using induced pluripotent stem cells (iPSC) derived from dermal papilla cells with a 3D biodegradable scaffold.” I interviewed Dr. Terskikh in 2017 and he promised me another one last year. However, due to pending plans related to Stemson Therapeutics, he delayed the interview. He has not responded to requests this year. Luckily, we still get a chance to hear him tomorrow in a special event.
My favorite question is on page 25: “What do you think will be the next technological “leap” in hair restoration?”
Out of 929 surgeons who were e-mailed this survey, only 201 surgeons answered this question. Hair cloning and stem cell therapies were the most popular responses:
How Many Hair Transplants Each Year?
Only 270 hair transplant surgeon members responded in time to this main survey question. After extrapolation and adjusting for anomalies, the ISHRS estimated that 735,312 hair restorations procedures were performed worldwide in 2019. This number represents a 16 percent increase from 2016, when an estimated 635,189 hair transplant procedures were tallied globally.
World Hair Transplant Surgery Totals by Region, 2019
Whenever I see such survey results, I am always highly skeptical about the annual global hair transplant totals. Although the ISHRS has around 1000 members across 70 countries, there are likely several thousand surgeons in developing countries who do not join this organization.
Many of these “missing” surgeons offer hair transplants as a side offering at their general cosmetic surgery and dermatological practice. And many hospitals have surgeons who perform hair transplants infrequently. e.g., during emergencies such as burning accidents or scalp injuries.
This under-representation is even more exaggerated when you consider the numerous sketchy “roadside” hair restoration clinics in many developing countries. Most of these assembly line type clinics would likely not even get ISHRS membership applications approved.
Moreover, many legitimate clinics and surgeons in poorer countries cannot afford to join the ISHRS and pay annual dues. And many probably do not deem it worth joining a US headquartered organization. Especially if most of their local clients do not care about certifications and international association memberships.
I would therefore not be surprised if the actual number of hair transplant procedures that take place worldwide is closer to 2 million or even higher. The ISHRS totals for vastly populated China and India are likely heavily underestimated. The cost of a hair transplant in these countries is a small fraction of that in the developed world.
Moreover, an increasing number of studies and articles suggest that rates of balding in China and India have gone up significantly in recent years. I think that there is also significant underestimation when it comes to places such as Turkey, UAE (Dubai) and Thailand. In fact, a number of online news articles from reputable sites suggest that 100,000 hair restoration procedures take place in Turkey alone every year.
Among the other interesting hair transplant statistics and related findings in this census/survey include:
An 85 percent to 15 percent split in the male versus female share of the hair transplant clientele. Not surprising.
A 66 percent “FUE only” versus 30 percent “FUT (strip) only” procedure type performed division. Also not surprising to me. See my past post on FUE versus FUT. The vast majority of FUE procedures are performed by motorized techniques, usually without suction.
Robotic-assisted FUE represents only 5.3 percent of all FUE procedures performed in the world.
99 percent of FUE surgeons used punches of less than 1 mm size. No-one used punches of less than 0.8 mm size.
When it comes to FUE donor sites: 92.5 percent included scalp hair; 7.5 percent included beard hair; and 2.4 percent included chest hair. Body hair transplants (BHT) are therefore still not very popular.
57 percent of patients needed only 1 procedure to achieve their desired result. A bit surprising to me. However, my guess is that many of these satisfied customer will eventually come back for a second procedure after some years due to further hair loss.
81 percent of patients have between 1000-3000 grafts transplanted during their first procedure.
87 percent of patients were between the ages of 26 and 45.
Only 13.4 percent of hair transplant surgeons’ patients came from a different country.
Present Hair Loss Treatment Survey
Another great section also does not involve any hair transplant statistics.
On page 16, there is a table titled: “How Often Various Treatments Were Prescribed to Patients in 2019“. 204 surgeons responded to this question. Not surprisingly, Finasteride and Minoxidil were by far the most popular treatment recommendations.
These two are the only ever FDA approved medications to treat androgenetic alopecia (aka male pattern baldness). The Finasteride recommendation breakouts in the table were split into 1% and 5% doses; as well as a separate topical Finasteride category.
I was surprised by the following findings:
A higher than expected 10.2 percent of responding physicians stated that they “always or often” prescribed oral Minoxidil to treat hair loss. In my past post on oral Minoxidil, I mentioned how it was become increasingly popular in Australia and Thailand. I would be nervous about the side effects of taking such a medication to treat high blood pressure. Especially a potential increase in body hair. However, it seems like many hair loss sufferers are biting the bullet and hoping to get superior results to topical Minoxidil.
Only 5.9 percent of the doctors “always or often” prescribed Dutasteride to treat hair loss. Very low in my opinion. Almost all comparison studies show that Dutasteride is superior to Finasteride in treating hair loss. But the former also has greater rates of side effects. It seems like hair transplant surgeons are reluctant to prescribe Dutasteride off-label to treat pattern hair loss. Even natural DHT blocker Saw Palmetto was recommended as a hair loss treatment more frequently (8.5 percent) than Dutasteride.
Around 30 percent of patients were often recommended to take natural supplements, vitamins, herbs and Biotin. Nutritional deficiency related hair loss is not common, and is usually temporary in nature. So this number is higher than I would expect.
