## Description

DHI (Direct Hair Implantation) is a hair transplant technique in which follicular units are extracted from a donor area using a small punch (similar to FUE) and then implanted directly into the recipient site using a Choi pen-like implanter device. The Choi implanter creates the recipient incision and inserts the graft in a single action, allowing precise control of graft angle, direction, and depth, and eliminating the need for separate recipient-site creation. DHI is marketed as a distinct technique but is, mechanically, an FUE variant that uses an implanter rather than a forceps for graft placement.

## Overview

DHI emerged as a branded technique in the mid-2010s, particularly popularised in the Turkish hair-transplant market. The Choi implanter offers theoretical advantages over traditional forceps placement: faster implantation, better preservation of graft handling, more precise control of angle and depth, and the ability to implant into existing hair without prior site-making. The trade-off is a steeper learning curve for the implanting technicians and higher consumables cost (each pen requires sterile cartridges).

## FAQs

### How does DHI compare to FUE?

DHI and FUE share the same extraction technique. They differ in implantation: FUE uses a forceps to place each graft into a pre-made recipient site, while DHI uses a Choi pen-like implanter to create the site and place the graft in one action. Outcomes (graft survival, density, naturalness) are broadly comparable in experienced hands.

### Is DHI better than FUE?

Not categorically. DHI's advantages — faster implantation, better angle/depth control, ability to implant into areas with existing hair without prior site-making — are real but modest. The single largest determinant of outcome is the operating team's experience and skill, not the implantation tool used.

### How many grafts can be done in one DHI session?

Typical sessions place 1,500-3,500 grafts. The maximum is limited more by the donor area than by the implantation technique. Some clinics offer multi-day sessions for larger graft counts.

### Will my native hair be damaged?

DHI allows implantation between existing hairs without first creating recipient sites, theoretically reducing the risk of damaging native follicles. In practice, some shock loss of native hair is normal and usually reversible.

### How long until I can fly home?

Most surgeons permit flying 2-3 days after DHI. Avoid pressing the seat headrest against the back of the head; use a neck pillow. Drink plenty of water to prevent dehydration that can compromise graft survival.

### What happens if the technician does most of the work?

In many busy hair-transplant clinics — particularly in Turkey — much of the implantation work is performed by trained technicians under the surgeon's supervision. Outcomes are tied to the team's experience and to the surgeon's planning and oversight. Confirm in advance who performs which part of the procedure and whether the named surgeon will be present throughout.

### Why do some clinics quote DHI sessions in graft counts and others by area?

Pricing models vary significantly. Per-graft pricing is more transparent and allows comparison between clinics — the surgeon estimates the required graft count after consultation. Per-session pricing typically caps the number of grafts and is less directly comparable. Per-area pricing is the least transparent and is generally avoided by experienced patients.

### Can I have a DHI procedure if my hair has been previously transplanted?

Yes — DHI can implant grafts between existing transplanted or native hairs without first creating recipient sites, making it well-suited to revision and refinement work after a previous transplant. The surgeon should review the existing hair pattern and donor area before quoting.

## Alternative treatments

- **Sapphire FUE** — Same FUE harvest with sapphire blades for the incisions; comparable cosmetic result, lower per-graft cost.
- **FUT** — Higher graft yield per session for advanced baldness; linear-scar trade-off.
