For the best results, there are two goals that we strive for. First, we want to make sure that the follicles can be extracted safely, without incurring damage to them. And secondly, we want to make sure that the patient can handle the incisions without incurring abnormal levels of scarring. Therefore we conduct Follicular Unit Extraction Feasibility tests.
As an example, with individuals of African descent, there is a relatively large risk of both transection (i.e. damage) and scarring. The shape of the hair follicles in these patients is curved, not straight. Encompassing atypically shaped follicles with punches can be challenging. The design of uGraft is intended to help overcome this challenge. But we still want to be clear about the rate of transection for the patient. Therefore, we perform a test extraction. [ Update: June 27, 2016: Dr U has invented an unconventional curved non-rotary punch called UPunch Curl which is capable of successfully extracting tightly curled afro-textured hair by FUE in all situatuions tested without the need for pre-testing ]
Some patients of African descent carry a very high risk of scarring, including keloids. Others may develop a normal extent of scar tissue. The test extraction also helps to determine this before a decision is made to proceed with a full surgery. To read more about FUE hair transplants in African Americans,
