Follicular unit extraction is one of two primary methods of obtaining hair follicular units, naturally occurring groups of one to four hairs, for hair transplantation. The follicular units are harvested one-at-a-time from the back of the head (the “safe” zone) and implanted in the balding areas.

FUE (punch) and how is it different from FUT (strip)

A Follicular Unit Extraction (FUE) hair transplant is a surgical procedure used to treat hair loss by transplanting individual hair follicles from a donor area, typically the back or sides of the scalp, to areas affected by balding or thinning hair. FUE differs from Follicular Unit Transplantation (FUT), also known as strip harvesting, in several key ways:

Harvesting Technique:

FUE: In FUE, individual hair follicles are harvested directly from the donor area using a small, punch-like instrument. The surgeon makes tiny circular incisions around each follicular unit, extracting them one at a time.
FUT: In FUT, a strip of skin containing multiple hair follicles is surgically removed from the donor area. The strip is then dissected under a microscope to separate individual follicular units for transplantation.

Scarring:

FUE: FUE typically results in tiny, dot-like scars scattered throughout the donor area. These scars are less noticeable and may be easier to conceal, especially for patients who prefer to wear their hair short.
FUT: FUT leaves a linear scar along the donor area where the strip of skin was removed. While efforts are made to minimize scarring and ensure proper closure, the scar may be more conspicuous, particularly for individuals with short haircuts.

Recovery Time:

FUE: FUE typically involves a shorter recovery period compared to FUT. Since there is no linear incision or sutures, patients may experience less discomfort and faster healing.
FUT: FUT may require a longer recovery time due to the need for sutures and the potential for post-operative discomfort associated with the linear incision. Additionally, patients may need to refrain from strenuous activities to avoid stretching the scar during the healing process.

Hair Density:

FUE: FUE allows for precise extraction of individual follicular units, which may result in a more natural-looking hairline and distribution of transplanted hair. However, the total number of grafts that can be harvested in a single session may be limited.
FUT: FUT typically allows for the extraction of a larger number of grafts in a single session, as the entire strip of donor tissue can be dissected to obtain follicular units. This may be advantageous for patients requiring a higher density of transplanted hair.

In summary, FUE and FUT are both effective hair transplant techniques, each with its own advantages and considerations. While FUE offers benefits such as minimal scarring and a shorter recovery time, FUT may be preferred in cases requiring a larger number of grafts. Ultimately, the choice between FUE and FUT depends on individual patient factors, preferences, and the recommendations of a qualified hair transplant surgeon.
