The procedure begins with the surgeon removing a donor strip from the donor site, which is often located on the back or side of the scalp. The donor strip is further cut into 3 sizes of grafts — the micro graft, the follicular unit, and the bi-follicular unit. The grafts are inserted into pre-cut micro slits that are strategically designed to aesthetically improve the density of your existing hair, lower the hairline, and fill in balding areas.

Preparation of the Donor Site

We shave about 1/2 an inch for donor harvesting. Leave your hair at least 1 inch long to cover up the suture site immediately after surgery, don’t cut your hair too short or you will have problem to cover the incision line right after the surgery.prep

Harvesting the Donor Area & Suturing

harvest1NHT Medical Center prides itself on using what we call the “Twilight Zone Anesthesia” technique to provide our patients with the safest and most comfortable procedure. We have the patient in the sitting position during donor harvesting. Then we close the donor site with suture.

Donor Strips

LFStrip1

Caucasian patient’s donor strips. High density, but finer hair.

LFStrip2

Asian patient’s donor strip. Coarser hair, but lower density.

The hair grows in groups. It may yield one to four hairs. These groups are called a follicular unit. A single follicular unit will contain 1 to 4 hairs. If a patient has a lot of hair then they will have a lot of 3 to 4 hair follicular units. If a patient has very thin hair, typically this patient will have 1 or 2 follicular units. High density vs low density.
Hair grows three to five years then it will shed. After three to five months it will regrow again. During this period we can’t see the hair from just looking at it. When the strip is removed, then we are able to see the follicles. These are the small dots in the tissue. This is about 10 to 15 percent of the total hair. So if the grafts were cut too small, a lot of the hair follicles will be removed. This is why we will use bi-follicular units often to yield as much hair as possible. Study compare chubby graft and skinny graft.

Cutting Under the Stereoscope

NHT Medical Center uses the latest state-of-the-art, MANTIS stereoscopes. These stereoscopes provide our skilled surgical technicians with detailed visibility when cutting the grafts. This follicular dissection technique provides the greatest quality of grafts, as well as preventing the least damage to the hairs.
Our surgical team has one surgeon and four technicians. Other hair transplant clinics typically only have 2 to 3 technicians.

Sizes of Grafts

We use three types of grafts.

  • 1 to 2 hair Single follicular unit
  • 2 to 3 hair Single follicular unit
  • 3 to 4 hair Bi-follicular unit

The surgical technicians divide the donor strip into the three sizes of grafts.
A combination of each of these types of grafts will provide a natural and dense looking result.

Slits Making

There are two different types of slits in the photos (horizontal and vertical).

The horizontal slits are made for one or two hair grafts. This creates a softer and more natural hairline. The next three lows of vertical slits are for 2 to 3 hair grafts. Then behind those rows, there will be 3 to 4 hair grafts to create the thickness and dense part of the hairline.

The cowlick/vertex area is the center where the slits will be made by the surgeon in a circular/spiral direction. All the silts are made for 3 to 4 size of grafts.

Implantation of Grafts

Depending on the size of the coverage area, two to three surgical technicians implants the grafts. The technicians use micro forceps to pick up the grafts and insert them into the pre-cut slits. The direction of the slit is decided and created by the surgeon.

Immediately After the Surgery

Immediately after the surgery, the patient will have to wear a bandage over his/her head to provide pressure to the donor incision site.
Patients can wear a hat to cover up the bandage.
After 24 hours, the patient may remove the bandage themselves.

Two Weeks Post-Op

These pictures were taken after the surgery.

The first picture was taken right after the procedure. Take a look at all the transplanted hairs on his scalp. In about 7 to 10 days after the surgery, the scabs begin to come off.

The second picture was taken two weeks after the procedure. Note that all the scabs are gone.

Undetectable Donor Area Scar

The surgical technique to reduce the appearance of the donor scar has improved remarkably in the last five years.
A lot of patients will have nearly invisible donor scar results, as the photos show below. Each person’s skin is different, so we can’t guarantee that each individual’s results will be perfect.
