DHI Hair Transplant
Precision-driven implantation for natural-looking results no shaving required.
At Rehaira, we perform DHI (Direct Hair Implantation) to offer patients the most refined, personalized hair restoration experience available today. This advanced technique allows for the direct placement of hair follicles into the recipient area using a Choi implanter pen without the need to open channels beforehand.
Unlike other implantation methods, DHI offers superior control over angle, direction, and depth producing dense, natural, and aesthetically tailored results.

What is DHI?
DHI is a modern implantation technique in which harvested follicles are directly implanted into the scalp using a pen-like device known as the Choi implanter.
What sets DHI apart is that no incisions or channels are opened before implantation. Instead, follicles are gently inserted in a single, controlled motion minimizing tissue handling and allowing for precise placement even between existing hairs.
It’s important to note:
DHI refers specifically to the implantation method.
Hair follicles are still typically extracted using the FUE (Follicular Unit Extraction) technique, after which DHI takes over during the placement phase.
Who Is It For?
DHI is ideal for individuals who:
-
Want a no-shave or partially-shaved transplant experience
-
Require high density or refined hairline design
-
Have existing native hair and want to preserve it
-
Are undergoing a second hair transplant
-
Have mild to moderate thinning or localized baldness
Our medical team will determine your suitability during the consultation process, based on scalp condition, donor area capacity, hair type, and design expectations.

How It Works – Step by Step
-
Consultation & Planning
Scalp analysis, donor capacity measurement, and customized hairline design. -
Anesthesia Application
The appropriate type of anesthesia local or general is determined based on the patient’s specific needs and comfort. -
FUE Extraction
Hair follicles are individually harvested from the donor area using a micro punch (typically 0.6–0.9 mm in diameter). -
Implanter Preparation
Grafts are gently loaded into multiple Choi pens (usually 5–6 pens of varying sizes), managed by trained assistants to ensure continuous workflow. -
Implantation
Each follicle is implanted directly into the scalp using the Choi implanter pen no pre-opened channels are required. This allows for precise control of angle, depth, and density. -
Post-Procedure Wash & Aftercare
The first wash is performed at the clinic one day after the procedure. After that, patients are guided on how to care for their scalp and apply special solutions at home.
Recovery Timeline
-
Day 1–3: First wash at clinic, return to light daily activities
-
Week 2: Shedding may begin this is normal and temporary
-
Month 1: Shock loss phase ends
-
Month 3–6: Visible regrowth begins
-
Month 12–18: Final results become fully visible

Frequently Asked Questions
DHI (Direct Hair Implantation) is a technique where hair follicles are extracted using the FUE method and then implanted directly into the recipient area with a Choi implanter pen. In this method, there is no separate channel-opening stage as the follicle is placed in one motion.
In both methods, hair follicles are extracted using FUE. In DHI, implantation is performed with a Choi implanter pen without opening channels beforehand, which allows grafts to be placed without damaging existing hair. In FUE Sapphire, channels are prepared using sapphire tips before implantation, which is often preferred for covering larger, completely bald areas.
No. The micro-sized entry points heal quickly and do not leave visible scars.
DHI is suitable for patients who want to increase density between existing hair, refine their hairline, or restore small areas without shaving or with minimal shaving.
Crusting usually disappears within 5 to 7 days. Mild redness may persist for a few days. Most patients return to daily activities within 1 to 2 days.
In a single session, 2,000–3,500 grafts are typically implanted. In certain cases, with a larger and well-coordinated medical team, it is possible to reach 4,500–5,000 follicles.
Initial hair growth begins around 3 to 4 months after the procedure. Noticeable improvement is visible by 6 to 9 months, with full results in about 12 months.
Yes. The transplanted hair comes from the donor area, which is resistant to hair loss, and therefore the results are permanent.
