FUE has a long learning curve longer than that of the traditional FUT procedure. FUE requires long hours of patient learning under high magnification. Once you take up FUE as a profession, you are married to it since it requires the whole day to accomplish if the doctor is doing the harvesting himself. Most doctors cannot-
Use high magnification
Sit for long hours in difficult postures
They usually cannot leave their lucrative dermatology/ plastic surgery practice they are used to in favour of FUE which requires complete sacrifice of time and attention.
Leave doing FUT procedure which gives them a lot of free time for other avocations. (A strip surgeon typically spends just one hour)
Lastly, FUE learning centers are few. Since it is a new technique, most centers remain closeted with their technique and do not open their doors to those seeking FUE training.
