Regrowth previously included a list of all hair transplant surgeons certified by the American Board of Hair Restoration Surgery (ABHRS). However the list is constantly growing and changing as new hair transplant surgeons are certified by the board, so we have decided to link directly to their membership list. The board is now international and not only includes hair restoration surgeons within the United States but countries across the world. The ABHRS is the only entity which certifies transplant surgery as a specialty and conducts the same types of oral and written exams for certification which other board certifications include.
