Evolution of the Follicular Unit Extraction (FUE) Technique

The follicular unit extraction (FUE) technique for hair transplantation has evolved significantly with advancements in surgical instruments, leading to more natural results, faster recovery, and less damage to donor areas. The procedure involves extracting follicular units from donor areas using punches and implanting them in recipient areas. The use of precise tools like the sapphire blade reduces trauma, bleeding, and postoperative edema, enhancing aesthetic recovery. The technique is highly dependent on the surgeon's skill and experience, requiring a significant learning curve to ensure safety and effectiveness.
