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
Harvesting the Donor Area & Suturing
Caucasian patient’s donor strips. High density, but finer hair.
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
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.
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.
For the vertex-
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
Immediately After the Surgery
Patients can wear a hat to cover up the bandage.
After 24 hours, the patient may remove the bandage themselves.
Two Weeks Post-Op
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.
