Follicular Unit Extraction: Advances and Challenges

In 2009, Follicular Unit Extraction (FUE) was described as a hair restoration technique that individually removes follicular units, offering advantages like less invasiveness, reduced pain, and no linear scarring. Challenges included a high transection risk and a steep learning curve, with initial transection rates at 5.6%, which could be reduced to less than 2% with experience. The SAFE System, using a dull punch, was developed to lower transection rates, with reported rates between 1.3% and 4% depending on the punch size. FUE was also less tissue-removing compared to traditional strip harvesting and allowed patients to wear hair short. The document noted the potential for FUE to become the standard for graft production due to improvements in techniques and instruments, predicting decreased operating times and costs, and the advent of mechanized and robotic technologies. However, the document also acknowledged the scarcity of published reports on FUE and based its information on anecdotal evidence.
