As the person who pioneered FUE, it is now the most popular hair transplant done worldwide. The doctors starting doing FUE when I published the first paper on the subject here: https://baldingblog.com/wp-content/uploads/pdf/mp-2002-fue.pdf. The public started to demand it, and within a year, doctors from all over the world were offering it but were doing it very poorly. Then, I licensed the hair transplant robot that we invented in 1998 to hopefully standardize the FUE. Over time, instruments got better and better and so did the doctors. Now, in every country in the world, FUE is a standard procedure for hair transplantation. Be careful as not all doctors perform FUE well.
