He has published numerous articles in medical journals and has been invited to deliver scientific papers at over 150 medical meetings throughout the world, the last three at the June 2015 World Congress of Dermatology, where he was also Chairman of the section of the meeting devoted to hair restoration surgery. He has written or co-authored 38 chapters on hair transplantation for dermatology and plastic surgery medical textbooks, eleven of them from 2006 to 2015, and is currently co-writing 4 chapters for 4 more textbooks. Nobody has remotely been honored by so many requests to author textbook chapters. His own textbook, Hair Transplantation, a multi-author work, has been widely considered the standard reference text for hair transplant surgeons from the publication of the first edition to the fifth published in 2011; it has been translated in Spanish, Korean and Chinese. He has been listed in Castle Connolly’s “Top Doctors”: New York from 2007 to present and has served on many journal editorial boards; at present he is a contributing editor for the Journal Dermatologic Surgery. Dr. Richard Shiell, at the time, the editor of Hair Transplant Forum International, the official publication of the International Society of Hair Restoration Surgery, wrote this about Dr. Unger:

comma When the history of hair restoration surgery is written in future years, the outstanding giant of our profession in this first half century will most likely not be a Japanese pioneer or some North American surgical entrepreneur, but Walter P. Unger, MD, a dermatologist from Toronto, Canada. His talents have shone like a beacon for over 20 years and his influence has been immense. We have all bathed in his illuminating insights while we avidly read his three books, 26 textbook chapters, and innumerable scientific papers. comma

Dr. Unger practices and lives in New York and Toronto with his wife Marcia. They have eight children. Dr. Unger’s past-times include: swimming, golf, travel, reading, and spending time at his farm.
