According to Dr. Umar, the µGraft device incorporates a number of unique features. Unlike traditional straight FUE punches, the µGraft’s cutting axis angles away from the graft, creating a gentle pulling action on the follicle and minimizing damage to the graft. This pulling action may also offer a distinct advantage in beard and body hair transplantation where the hair follicles curve beneath the skin. This is because it purportedly cancels the curve of the follicle, greatly reducing or eliminating the risk of transection (cutting) of the graft.
Another stated advantage of the µGraft is its irrigation system. This system provides a number of distinct advantages. First, it gently flushes impacted grafts from the punch without damaging them (other systems require pulling impacted grafts from the punch with tweezers that can result in trauma). Second, the irrigation system leaves a film of chilled physiologic fluid after each punch that helps to sustain the grafts in the time between scoring and actual extraction (a critical time interval crucial to FUE hair growth yield). Next, the film of fluid also keeps the surface lubricated; reducing the time it takes for the punch’s cutting edge to be dulled. Finally, it creates a seal that is partly responsible for the gentle pulling action that helps separate the graft from its tissue attachments.
Dr. Umar states that he has been using the µGraft for several years and believes it to be superior to all the punch systems currently available. At this time, he is working put the µGraft into production and making it accessible to other physicians.
That said however, there are many other viable FUE extraction tools and each physician has their own preference and belief as to which one is "superior". Evaluating a tool independent of the physician using it becomes a futile task. Thus, prospective patients should always put the skill and experience of the operating physician above which tool they use when selecting a surgeon for hair transplantation.
