An Update on Hair Restoration

Abstract

Hair restoration therapy has evolved significantly over the past few decades. Aesthetically pleasing and natural results are achieved with modern techniques utilizing follicular unit transfer. While the concept remains the same, various techniques have been developed for harvesting follicular units safely and reliably. Here, we review some of the techniques of obtaining follicular units for transplantation, medical treatment of androgenetic alopecia, and future directions in hair restoration therapy.
