What is autologous hair transplantation? Areas where hair can be added and differences from AGA treatment

Autologous hair transplantation is a surgical procedure that transfers your own hair follicles from the back and sides of the scalp to areas where hair thinning is a concern[1]. While hair follicles can be placed in areas without hair, the progression of existing non-transplanted hair must be managed separately[2].

Which areas can be augmented with autologous hair transplantation?

Autologous hair transplantation directly increases hair by placing transplanted hair follicles at the recipient site. Hair follicles are harvested by unit from donor areas in the back and sides of the scalp and transplanted to areas such as the hairline and crown[1]. The range that can be transplanted is determined not only by your wishes but also by the donor density, number of follicles, and hair thickness[3].

The difference from AGA treatment: moving hair versus protecting hair

Hair transplantation is a surgical treatment that moves hair follicles, while AGA drug treatment is intended to slow the progression of existing hair. Since AGA can progress in areas where transplants were not performed, surgery and medication are not opposing choices[2].

Harvesting methods center on two main approaches: FUE and FUT

The representative harvesting methods are FUE, which extracts hair follicles one at a time, and FUT, which separates hair follicles from scalp tissue harvested in a strip[3]. The scar shape, shaving area, and amount harvestable differ, and the evidence basis for direct comparison suggesting one is superior for everyone is limited[1].

Why does it take time to assess results?

Most transplanted hairs are shed once after surgery, and new hairs begin to grow from the hair follicles. Hair growth becomes visible over several months, and the final evaluation is generally assessed around one year post-operation[4]. It is important not to judge hair engraftment based solely on appearance at an early stage.

What is decided together during the consultation?

During the consultation, we confirm the cause and progression of hair thinning, donor density and hair quality, and your desired treatment area[3]. We make individual judgments including how to allocate limited donor hair between the hairline and crown, and how to continue treatment of existing hair.
