Adrenaline Infiltration in the Recipient Area During Follicular Unit Extraction Using the Implanter Technique: A Prospective Observational Study

This prospective observational study involving 50 patients assessed the efficacy and safety of using dilute adrenaline (1:200,000) infiltration in the recipient area during implanter-based FUE hair transplantation. The results showed a significant reduction in intraoperative bleeding, improved visualization, and enhanced control during graft implantation, with no major local or systemic complications. Transient head heaviness was reported by 14% of patients but resolved spontaneously. The study concludes that adrenaline infiltration can improve procedural efficiency and graft stability without compromising safety, though further controlled studies are recommended for long-term evaluation.
