Hair transplantation techniques have been transformed by Follicular Unit Extraction (FUE). The objective of this review paper is to examine the numerous FUE applications in the context of hair restoration and elsewhere. Individual hair follicles are removed from the donor location and transplanted to the recipient site during FUE. The versatility of FUE has led to its usage in non-hair applications such the treatment of acne scars and scar concealment as well as in the treatment of androgenetic alopecia, scarring alopecia, eyebrow and eyelash rebuilding, and facial hair transplantation.
FUE has been a ground-breaking procedure for treating androgenetic alopecia because, unlike the conventional strip harvesting method, it may remove hair follicles without creating a linear scar. It offers a minimally invasive method with results that seem natural. Scarring alopecia, which is characterized by permanent hair follicle damage, might also profit from FUE since it enables the transplanting of healthy follicles into scarred regions.
FUE has also become more popular in the field of aesthetic operations. With FUE, eyebrow and eyelash density can be restored and improved, making eyebrow and eyelash repair applications increasingly popular. Demand for facial hair transplantation, including the restoration of sideburns, mustaches, and beards, has also increased, and FUE has shown to be a successful method in these situations.
It's interesting to note that FUE has uses outside of the hair industry. It offers a practical option for scar repair and has demonstrated potential in the treatment of acne scars. Additionally, FUE can be used to disguise scars by implanting hair follicles to cover scars on various body parts.
FUE is a useful tool in the fields of hair restoration and aesthetic medicine due to its adaptability and efficacy in these various applications. This study emphasizes the potential of FUE to enhance cosmetic outcomes and boost patients' quality of life by examining the procedural elements, benefits, limitations, and outcomes of FUE in diverse applications.
