How hair transplant techniques evolved: FUT, FUE and today's tools

Hair transplantation developed from larger skin grafts to the use of small, naturally occurring groups of hair follicles. Today, FUT and FUE describe ways of obtaining donor grafts. Implantation devices and recipient-site blades describe other parts of the procedure. Understanding the difference helps patients compare what a clinic actually proposes.

A short history

The ISHRS historical overview describes transplantation experiments in 1822, Okuda's work in Japan in 1939 and Orentreich's 1959 publication on donor dominance. Donor dominance explains why transplanted follicles can retain characteristics of the donor area. Later, smaller grafts and follicular-unit techniques helped refine hair placement and appearance.

What changed with follicular-unit surgery?

A follicular unit is a small natural group of hair follicles. A graft is the piece of tissue moved during surgery; it can contain more than one hair. Using these groups allows the surgeon to plan their distribution across the recipient area. The graft count and the hair count are therefore different measures. Our FUE beginner guide illustrates this distinction.

FUT: obtaining grafts from a strip

In FUT, a strip of hair-bearing scalp is removed and divided into grafts. Closure leaves a linear donor scar. FUT remains an available surgical approach; it should not be described as universally obsolete. The ISHRS guide to surgical treatments explains the two main donor-harvesting approaches.

FUE: obtaining grafts individually

FUE uses small circular incisions to obtain individual follicular units. It avoids a single strip incision but creates multiple small donor wounds. It is not scar-free: ISHRS explains that both harvesting methods leave scars. The choice involves the donor area, treatment goals and a surgeon's assessment.

Where do DHI, sapphire blades and robotics fit?

DHI commonly refers to an implantation approach using an implanter. A sapphire blade is a tool used to make recipient sites. These labels do not, by themselves, describe a separate method of harvesting donor grafts. Ask how the grafts will be obtained and how they will be placed. ISHRS discusses confusing FUE terminology.

Robotic devices can assist parts of surgery. They do not remove the need for diagnosis, planning and accountable clinical judgment. The ISHRS position statement on scalp surgery treats robotic harvesting tools as surgical instruments operated within a clinical procedure.

Is PRP a transplant technique?

PRP is prepared from a patient's blood and may be discussed as a separate or supporting treatment. It is not a method of moving grafts. Preparation and treatment protocols vary, and an improvement in graft survival should not be promised. The ISHRS-hosted PRP overview explains the variability and limitations of this treatment.

What should a patient ask today?

• Which method will be used to obtain the grafts, and why?
• Who will perform the surgical stages?
• What donor scarring and limitations should I expect?
• What follow-up is included, and how will progress be assessed?

A technique's name is only part of a treatment plan. Learn more about Ulusan Clinic and its doctors, or contact the clinic to discuss an assessment.
