Hair Transplantation (FUE / FUT)
Surgical redistribution of donor follicles to rebuild hairlines and density
이 치료에 대해
Hair transplantation surgically redistributes follicular units from a stable donor zone, usually the occipital or temporal scalp, to the hairline, frontal scalp, crown, eyebrows, beard, or selected scars. FUE (Follicular Unit Excision) removes units individually with small punches, whereas FUT removes a donor strip that is microscopically dissected into follicular units. Both require recipient-site creation and graft placement.
DHI mainly describes an implantation workflow using an implanter pen; it is not a third donor-harvesting category equivalent to FUE or FUT. “Sapphire FUE” and robotic assistance similarly describe instruments or workflow variations. Naturalness and survival depend heavily on donor planning, transection control, graft handling, recipient-site angle, and physician oversight. Transplantation redistributes a finite donor supply rather than creating follicles, so progressive AGA/FAGA still requires a long-term plan that may include medical stabilization.
작용 기전
Occipital and temporal follicles tend to be less androgen-sensitive than frontal and crown follicles and retain part of this donor-site behavior after transplantation. FUE incises around individual units with a small punch, while FUT microscopically dissects units from an excised donor strip. Grafts containing approximately 1-4 hairs are placed into recipient sites designed for direction, angle, and density and enter a new growth cycle after revascularization. Native non-transplanted hair may continue to miniaturize from AGA/FAGA, and donor supply remains finite.

기대 효과
Transplanted shafts often shed 2-8 weeks after surgery, with regrowth usually beginning around 3-4 months. Major assessment is made at 9-12 months, while crown growth and caliber maturation may take 12-18 months. A meta-analysis of 57 surgical alopecia studies reported pooled graft survival of approximately 84.98-93.11% and satisfaction of 89.70-97.00% in nonscarring alopecia, depending on the graft method. These heterogeneous pooled data include older techniques and are not a guarantee for an individual clinic. Surviving grafts can remain long-term, but native hair may continue to thin.

위험 및 부작용
Postoperative pain, forehead edema, bleeding, crusting, folliculitis, infection, temporary shock loss, itching, sensory change, poor graft survival, inadequate density, unnatural hairline direction, and asymmetry can occur. FUE may cause punctate hypopigmented scars, follicular transection, and moth-eaten donor thinning from overharvesting. FUT may cause a linear scar, wound separation, hypertrophic scar or keloid, and prolonged numbness. Rare complications include skin necrosis, serious infection, and vascular or nerve injury. Delegating surgical steps to unlicensed personnel is a major safety risk.
