FUE vs. DHI Hair Transplants: Technical and Clinical Differences
Follicular Unit Extraction (FUE) and Direct Hair Implantation (DHI) represent the two primary methods used in modern hair restoration. While both techniques rely on the extraction of individual follicles from a donor area, they diverge significantly during the implantation stage. Selecting the appropriate method depends on the extent of hair loss, the desired density, and the patient's preference regarding surgical preparation and recovery timelines.
Frequently asked questions
Which technique provides the highest hair density?+
DHI generally allows for higher density because the Choi pen permits closer placement of follicles without damaging existing hair or surrounding tissue.
Is DHI more expensive than FUE?+
Yes, DHI is typically more expensive due to the specialised equipment used and the longer duration the surgeon must spend on the meticulous implantation process.
Can I have a hair transplant without shaving my head?+
DHI is the preferred method for unshaven transplants, as it allows the surgeon to work between existing long hairs without a full shave.
What is the typical graft limit for FUE vs. DHI?+
FUE is often used for large sessions up to 4,500–5,000 grafts, while DHI is typically limited to 2,000–3,500 grafts per session due to its time-intensive nature.
