What is DHI hair transplant?
DHI (Direct Hair Implantation) is a variation of FUE that uses a Choi implanter pen to create the recipient channel and implant the graft in a single motion — eliminating the separate channel-creation step used in standard FUE. DHI allows denser graft packing (60–75 grafts/cm²) and supports an unshaven recipient zone for sessions under 2,500 grafts.
At Eyeglow Health in Istanbul, DHI is performed at our partner accredited hair clinic by a board-certified hair restoration surgeon with documented DHI volume of 1,000+ cases. The Turkish Ministry of Health International Health Tourism Authority Certificate is held by both Eyeglow and the partner clinic. We follow International Society of Hair Restoration Surgery (ISHRS) consensus on technique selection — DHI vs FUE is a case-by-case decision, not a marketing-driven default.
DHI is the right technique for medium-sized sessions (1,500 to 3,500 grafts) with high density target, unshaven recipient preference, or female hairline restoration. For large sessions (4,500+ grafts) standard FUE remains faster and equally effective. That decision belongs to a hair surgeon who has personally examined your scalp and Norwood pattern — not to a marketing brochure or a price-list page.
From first consultation to recovery at home
- 01
Online consultation + photo assessment
You share four standardised photographs and your hair-loss history. Our hair surgeon reviews your case, determines whether DHI is the right technique (best for smaller-to-medium sessions with high density target or unshaven recipient preference), and provides a written graft estimate before a quote is issued.
- 02
Pre-operative assessment in Istanbul
On day 1: scalp examination, donor area density measurement, recipient hairline design, blood tests (CBC, INR, hepatitis B/C, HIV per Turkish Ministry of Health protocol) and informed consent. DHI requires donor shaving; recipient area can remain unshaven for cases under 2,500 grafts.
- 03
Hairline design + density target planning
The hair surgeon walks you through the planned hairline shape, graft count by zone, and density target per cm². DHI typically allows denser packing (60–75 grafts/cm²) than standard FUE (40–55 grafts/cm²), making it suitable for crown coverage and patients prioritising thick visual density.
- 04
DHI procedure (7–10 hours)
Step 1: Donor follicular units harvested with 0.7–0.9 mm FUE micropunches. Step 2: Each graft is loaded into a Choi implanter pen — a thin needle device with a hollow tip. Step 3: The pen creates the recipient channel AND implants the graft in a single motion, with no separate channel-creation step. Performed under local anaesthetic with light intravenous sedation. The surgical team typically uses 4 to 6 Choi pens rotating to maintain implantation pace.
- 05
Day 1 wash + day 3 review
First wash with antiseptic solution at the clinic on day 1. Mild redness and forehead swelling for 3 to 7 days. Crusts shed by day 10 to 14. Shock loss (temporary shedding of grafts and surrounding hair) between weeks 2 and 8 is normal; grafts remain alive and regrow.
- 06
One-year structured aftercare
1, 3, 6 and 12-month photographic reviews. First new growth visible at month 3 to 4; 50–60 percent of final density at month 6; final result at month 12 to 18. Concurrent finasteride and minoxidil guidance provided per ISHRS recommendations to protect surrounding native hair.
DHI vs FUE vs Sapphire FUE vs PRP
The right hair-restoration technique depends on case size, density target and donor reserve. Here is how the four main options differ:
| Aspect | DHI | FUE | Sapphire FUE | PRP |
|---|---|---|---|---|
| Channel creation | Choi pen — channel + graft in one motion | Separate step with sapphire/steel blade | Sapphire blade — separate step | Microneedle — supportive only |
| Density target | 60–75 grafts/cm² (densest packing) | 40–55 grafts/cm² | 45–60 grafts/cm² | Not applicable |
| Best case size | 1,500–3,500 grafts (medium) | 2,000–4,500+ grafts (any) | 2,000–4,000 grafts | Adjunct, not a session |
| Unshaven recipient | Possible for <2,500 grafts | Limited | Limited | Always unshaven |
| Procedure time | 7–10 hours | 6–9 hours | 6–9 hours | 60 minutes |
| Recovery time | 7–10 days crusts | 7–10 days crusts | 5–8 days (smaller crusts) | Same day |
| Price relative | Premium | Standard | Premium | Adjunct |

Are you a candidate for DHI hair transplant?
You may be a good candidate if
- You want the highest possible density in the recipient zone (DHI allows 60–75 grafts/cm² vs 40–55 for standard FUE).
- You prefer the unshaven recipient option (possible for sessions under 2,500 grafts) so you can return to work or social life immediately.
- You are targeting frontal hairline + mid-scalp coverage where density visibility matters most.
- You meet standard hair-transplant candidacy: Norwood 2–5 pattern, stable hair loss for 12+ months, sufficient donor density, realistic expectations.
Standard FUE may be a smarter choice if
- You need 4,500+ grafts in a single session — standard FUE is faster and equally effective at large case sizes.
- You want the absolute lowest price — DHI premium is 20–30% over standard FUE due to Choi pen consumables.
- You have advanced Norwood 6–7 pattern — donor reserve is the limiting factor, not the implantation technique.
- Active scalp infection, scarring alopecia, or other contraindications to hair surgery (see FUE candidacy criteria).
Disclaimer. Information on this page is consistent with International Society of Hair Restoration Surgery (ISHRS) practice standards, American Hair Loss Association (AHLA) guidelines and Turkish Ministry of Health International Health Tourism Authority Certificate requirements. The choice between DHI and FUE is a case-by-case clinical decision based on case size, density target, donor reserve and surgeon experience — not a marketing-driven default.
Realistic outcomes — the risks that actually matter
Every hair-restoration procedure has measurable risks. We list them here in the same plain language our hair surgeon uses in your consultation:
Same risk profile as FUE
DHI uses the same FUE-style follicular unit extraction; the difference is at the implantation step. Therefore the donor area risks (tiny dot scars, transient numbness, folliculitis) are identical to standard FUE. The Choi pen does NOT eliminate hair-transplant risks — it changes how grafts are implanted, not whether they survive.
Slightly higher graft trauma risk
Loading grafts into the Choi pen and the single-step channel+implant motion subject the graft to slightly more mechanical handling than the slower forceps-implantation method used in standard FUE. With experienced DHI surgeons graft survival remains 90–95%; with inexperienced operators it can be lower. We work only with hair surgeons who have a documented DHI volume of 1,000+ cases.
Density expectation vs reality
DHI can pack 60–75 grafts/cm² but this does not automatically produce 60–75 hairs/cm² visible result — single-hair grafts at the hairline plus multi-hair grafts behind give a natural look that depends on the surgeon's design, not the implantation density alone. We are honest in consultation about what DHI can and cannot do versus FUE.
Cost premium without proportional benefit
For large sessions (4,500+ grafts), the DHI premium over standard FUE may not produce a proportional aesthetic benefit. We recommend standard FUE for mega-sessions and reserve DHI for small-to-medium dense-packing or unshaven recipient cases.
