Modern hair transplantation has evolved from punch hair transplantation into more advanced treatment options.1
Currently, the most common hair restoration techniques for commercial use are follicular unit transplantation (FUT) and follicular unit excision (FUE).2 FUT is an invasive surgical procedure where a long strip of scalp with hair follicles is excised in order to get donor hair grafts or follicular units. A scalpel is used to cut and remove a part of the skin, while stapling and suturing are used for closure.3
In contrast, FUE utilises small punches to detach demarcated hair grafts (follicular units) from the scalp.4 FUE requires hair grafts to be harvested individually in a two-step method – sharp punch placed into the scalp and forceps to manually separate grafts – which can be very laborious and tedious due to volumes of up to 2,000 to 3,000 grafts.
With many of the issues and challenges with harvesting and implantation discussed above, advancements in artificial intelligence (AI), machine learning and vision have allowed for mitigation of many…
