DHI Hair Transplant

Direct Hair Implantation — Maximum density through Choi pen technology

DHI (Direct Hair Implantation) is a specialized hair restoration technique that implants extracted hair follicles directly into the scalp using an advanced medical device known as a Choi Implanter Pen. Unlike the traditional FUE method, DHI does not require the prior surgical opening of recipient channels. Instead, the creation of the insertion site and the implantation of the graft occur simultaneously in a single, fluid motion. This direct approach offers unprecedented control over the depth, angle, and direction of each implanted hair, resulting in an incredibly natural appearance. DHI relies on precision, making it the ideal choice for targeted hair densification, lowering high hairlines, and working within existing hair without requiring a full head shave. Clinical data shows that minimizing the time grafts spend outside the human body significantly increases their survival rate to nearly 99%. Our surgeons exclusively perform DHI to ensure maximum density, faster tissue recovery, and a completely undetectable, lifelong result.

Direct Implantation

Extraction and implantation in one step — shorter time outside the body, higher graft survival rate.

Higher Density Possible

The precise Choi pen technique allows grafts to be placed more densely than with classic methods.

Minimal Bleeding

No pre-opening of channels means less trauma to the scalp and faster healing.

Ideal for Densification

Perfect for hair densification in existing hair areas without damaging existing hairs.

Treatment Process

1

Consultation & Planning

Thorough analysis of your hair loss and planning of optimal results. We clarify whether DHI or FUE is the best method for your case.

2

Graft Extraction

Individual hair follicles are precisely extracted from the donor area with a fine micro-punch.

3

Direct Implantation with Choi Pen

The extracted grafts are immediately loaded into the Choi implanter pen and directly placed into the recipient area — channel opening and implantation in one step.

4

Aftercare & Results

Comprehensive aftercare with scheduled check-up appointments after 1 week, 3, 6 and 12 months for optimal results.

Frequently Asked Questions

What is the difference between DHI and FUE?
With FUE, channels are first opened, then grafts are placed. With DHI, both happen in one step with the Choi pen. DHI is especially suitable for densification and targeted areas, while FUE can be more efficient for larger areas.
Who is DHI especially suitable for?
DHI is especially suitable for patients who want hair densification in existing hair areas, for hairline work, or when maximum density is desired.
Is DHI more painful than FUE?
No, both methods are performed under local anesthesia and are virtually painless. Most patients report a comfortable experience.
How long does a DHI treatment take?
Duration depends on the number of grafts. A DHI session typically takes 4-8 hours, as each graft is individually placed with the Choi pen.
