DHT/DHI Hair Transplant: Advanced Techniques for Hair Restoration

Hair transplant techniques can be broadly divided into two basic categories: FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplantation). Here’s a breakdown of how these categories have evolved and led to the development of DHT and DHI Hair Transplant techniques:

There are three steps involved in any hair transplant

Extraction

In this step hair roots are extracted from donor area. Donor area can be any part of body. Normally we take scalp as a donor area, but this can be beard , chest, hands, legs, pubic area, axilla.

Storage

Grafts extracted in previous step are stored in solution outside the body. This solution can be normal saline, ringer lactate, or plasma (not recommended). Once extraction is over we move to next step.

Plantation

Insertion points are made in bald area, in simple words small holes are created in bald area with special instruments. The extracted grafts are planted one by one in bald area, or inserted in holes. This insertion can be done with different tools.

Entire modification in techniques is based upon modification in these three steps, either variation in time of each step or the instruments used in these steps.

Basic Methods of FUE and FUT Hair Transplantation

FUE (Follicular Unit Extraction)	FUT (Follicular Unit Transplantation)
Extraction: Involves extracting individual hair follicles from the donor area using dental motors. Storage: After extraction, the grafts are stored outside the body in normal saline or ringer lactate before being implanted. Plantation: Insertion sites or holes in scalp are made with simple hypodermic needle.	Extraction: A strip of scalp is surgically removed, and hair follicles are extracted from it under the microscope. Storage: After extraction, the grafts are stored outside the body in normal saline or ringer lactate before being implanted. Plantation: Insertion sites or holes in scalp are made with simple injection needle.

FUE to DHT (Direct Hair Transplant)

DHT is an advancement of FUE

FUE is the basic technology for hair transplants but has some drawbacks. It uses a high-speed dental motor, which can cause graft loss and result in gaps in the hairline. This technique is older, having come after the FUT hair transplant method. DHT Hair Transplant is an improvement over FUE. With DHT, the time the grafts spend outside the body is very short or even negligible. This reduction in body-out time helps improve the survival rate of the grafts. DHI Hair Transplant also offers benefits similar to DHT, ensuring better results for those seeking hair restoration.

Body out time is less

Extraction is with dental motor

Graft survival better than fue

Dental Motor

Extraction

The extraction process is with dental motor , which is similar to FUE.

Not Stored Outside Body

Storage

Graft storage time outside body is limited or is sometimes eliminated completely and the graft storage step is ommited.

Needle

Plantation.

Slits or holes for inserting grafts is done with injection needle as in fue. Grafts are planted immidiately after extraction. This reduces the time the grafts are outside the body, resulting in improved survival rates and a more efficient procedure.

DHT to DHI (Direct Hair Implantation)

DHT is an advancement of FUE

DHI is similar to DHT but differs in the implantation process. DHI Hair Transplant uses a Choi Implanter, a pen-like device with a needle for graft insertion. Although it appears more advanced, the Choi Implanter can cause more trauma to the grafts during insertion, as the Choi Implanter is nothing but a needle placed inside a pen; needles are more damaging to skin due to their shape leading to potential damage.

Extraction is with dental motor

Storage medium normal saline

Choi planter introduced

Graft survival 85-90%

Dental Motor

Extraction

The extraction process remains similar to fue i.e dental motor .

Not Stored Outside Body

Graft Storage

In DHI technique, graft storage time outside body is limited. Some clinics prefer immidiate insertion of grafts.

Plantation

Implanters are often used in hair transplants, but studies show they cause similar levels of trauma to the scalp as traditional FUE techniques. These implanters are essentially needles with a steel rod inside.

What is Neo DHT?

The precision of sapphire blades ensures seamless graft placement with minimal trauma, providing natural-looking results. The combination of these advanced tools helps Neo DHT Hair Transplant achieve a 99% graft survival rate.

NeoPlatinum DHT Hair Transplant is the most advanced hair transplant technique, developed by Dr. Nav Vikram, incorporating cutting-edge technology for optimal results. Here’s how Neo DHT works:

Now moving further neo DHT is more advanced than DHI / DHT Hair Transplant

which improves upon DHI by using cutting-edge tools like Nano Motors and Sapphire Blades.

99% graft survival rate

Natural-looking results

Faster Recovery

No Need for Incision Slits

High precision & density

Nano Motor

Grafts Extraction

NeoPlatinum DHT uses advanced nano motors weighing only 23 grams and operating at a low speed of 600-700 RPM. This low speed reduces the risk of damage to hair follicles during extraction.
The nano motors are equipped with a fail-safe mechanism that automatically shuts off if positioned incorrectly, ensuring grafts remain undamaged and leading to a higher graft survival rate.

Graft Storage

After extraction, the grafts are stored in a special culture media that mimics the natural environment of human skin. This prevents graft shock while the grafts are outside the body, ensuring their health and viability until implantation.

Sapphire Blades

Graft Implantation

For implantation, ultra-thin sapphire blades are used to create the recipient sites. These blades are designed to minimize disruption to surrounding hair, reducing the risk of shock loss.
The precision of sapphire blades ensures seamless graft placement with minimal trauma, providing natural-looking results. The combination of these advanced tools helps Neo DHT achieve a 99% graft survival rate.

What is the Difference Between DHT and NeoDHT?

When comparing DHT Hair Transplant, DHI, and NeoDHT, significant improvements have been made, particularly in terms of technology and outcomes.

One notable option is the DHI Hair Transplant, which offers specific advantages that may appeal to individuals seeking effective hair restoration solutions.

	DHT (Direct Hair Transplant)	NeoDHT (Neo Direct Hair Implantation)
Grafts Extraction	Dental Motor	Nano Motors
Weight	Weight 340 Grams	Weight 25 Grams
Speed	Speed 7000-21000 rpm	Speed 600-900 rpm
Power Input	Power input D.C 12-18 Volts	Power input D.C 2-3.5 Volts
Plantation	Choi Planter	Sapphire Blades
Thickness	Well Thickness 0.3 mm	Well Thickness 0.1 mm
Metal	Stainless Steel Metal	Titanium Metal
Size	Size 0.9-1.2 mm	Well Thickness 0.1 mm
Graft Survival Rate	Graft survival rates are lower (75% to 85%) due to the use of high-speed dental motors (7,000-21,000 RPM), which can cause graft damage.	Achieves a graft survival rate of 99% to 100% due to the use of slow-moving nano motors (600-700 RPM), which minimize the risk of damage.
Motor Speed and Technology	Both use heavy dental motors that operate at high speeds (7,000-21,000 RPM), which increases the risk of damage during extraction.	Uses lightweight nano motors (23 grams), operating at a slower speed of 600-700 RPM, making the procedure gentler and safer for the grafts.
Tools for Inserting Grafts	Uses simple needles for graft insertion, which can cause more trauma and less precision.	Utilizes ultra-thin sapphire blades and tongs for implantation, providing greater accuracy and minimal disruption to surrounding hair, resulting in a natural and seamless look.
Trauma and Recovery	The use of high-speed dental motors can cause more trauma during extraction, leading to swelling and longer recovery times.	With slower nano motors and advanced tools, NeoDHT causes minimal trauma, resulting in no swelling and virtually no downtime.
Blood Supply and Final Results	High-speed motors can reduce blood flow to the transplanted area, impacting graft survival.	Maintains healthy blood flow, ensuring better long-term results and healthier hair growth.
Donor Area Preservation	These methods may cause damage to the donor area, reducing hair density and affecting the potential for future transplants.	Ensures no collateral damage to the donor area. Even after extracting up to 5,000 grafts, the blood supply remains intact, preserving donor area density.
