The Choi implanter pen is a specialized medical device that looks like a pen with a hollow needle at the tip. It allows surgeons to create a recipient site and implant a hair follicle in one single motion. The pen controls the exact depth, angle, and direction of each graft, resulting in more natural-looking results and higher density.

Yes, DHI is the best technique for unshaved (no-shave) hair transplants. The donor area requires minimal shaving (or selective shaving in small patches that can be hidden), and the recipient area can remain completely unshaved. This makes DHI ideal for patients who need discretion during recovery.

DHI achieves higher density (80-120+ grafts per cm²) because the Choi pen creates very small recipient sites that can be placed closer together. The simultaneous channel-creation and implantation also means less swelling, allowing for tighter graft placement. This is especially valuable for hairline work.

Yes, DHI is typically 10-20% more expensive than standard FUE due to the specialized equipment (Choi pens are single-use), longer procedure time, and need for highly skilled technicians. In Türkiye, DHI starts from £2,500 compared to £1,800 for FUE, still significantly less than typical UK/US prices reported by patients.

A DHI procedure typically takes 8-10 hours for 2,000-3,000 grafts, longer than FUE because each graft is individually loaded into a Choi pen. The procedure includes breaks for meals and rest. Multiple technicians work simultaneously to load pens while the surgeon implants, maximizing efficiency.

DHI recovery is generally faster than FUE because there's less trauma to the scalp. Most patients can return to office work within 3-5 days. Redness and tiny scabs resolve within 7-10 days. With the no-shave option, the procedure can be virtually undetectable to others within 2 weeks.
