Hair Transplant: Follicular Unit Grafting (FUG)

What is FUG?

Follicular Unit Grafting (FUG) is a surgical technique to treat hair loss. Dr. Yael Halaas performs FUG transplants as an outpatient procedure at her New York City office.

What is the difference between hair transplant techniques?

Dr. Halaas uses two types of methods to restore the hair: Follicular Unit Grafting (FUG) and Follicular Unit Extraction (FUE). The main distinction between the two rests in how the hair is harvested.

Transplant Method Comparison Follicular Unit Grafting (FUG) Follicular Unit Extraction (FUE)
Harvesting method Strip of scalp Individual follicles extracted one-by-one
Procedure time Depends on the number of grafts, but generally 3-6 hours Labor intensive process, multiple session may be necessary
Graft survival and regrowth rate Typically produces a higher yield than FUE Lower individual graft survival rate than FUG
Scarring More noticeable linear scar at donor site, but can be hidden by hair growth Scars are more dispersed in donor site, making them almost imperceptible

How is FUG performed?

Also referred to as the “strip method”, the FUG procedure involves excising a patch of scalp with hair from a donor site and grafting it to a bald area. The donor site is typically located the back of the head.

Before the procedure, the scalp will be numbed. Dr. Halaas will remove a strip tissue, which is then closed as a fine linear scar. The removed tissue is then cut into smaller units under microscope dissection. To prepare the recipient site to receive the grafts, small holes are made in the scalp. The follicular units are then placed and carefully arranged so that the hair will look natural when regrowth occurs.

What is the recovery process?

Typically, patients can resume their normal activities in 24-48 hours. Strenuous activities or exercise should be avoided for about 10 days. Scabs are usually present at the recipient site for a week. After a FUG hair transplant, you may experience some numbness or tightness at the donor site. Any discomfort can be well managed with medication.

Who is the ideal candidate for FUG?

If you have permanent hair loss and adequate hair density at the back of the head, you may be an ideal candidate for FUG. Candidates should be in overall good health and have realistic expectations.

The Benefits and Risks of FUG


  • Results are permanent
  • High graft survival rate (usually higher than 90%)
  • Natural-looking results


  • Infection and healing problems (very rare)
  • Scarring (higher risk of scarring than the FUE method)
