Ensuring that the follicular unit remains intact and is dissected and implanted into the scalp in the shortest possible is essential for increasing the chances of the hair follicles surviving the process and growing. But whenever an assistant was not able to take care of this important aspect, it affected the results.
For the above mentioned reasons, a technique that leaves the follicular unit intact but at the same time advocates the use of three and four-haired follicular groupings for surgical hair restoration was evolved by the innovative hair transplant surgeons. This procedure was found to have many advantages over follicular unit transplantation.
A single hair follicular unit does not necessarily comprise a single hair 脫髮改善 and may contain 2-4 hairs in a single hole. When the follicular units are found very close to each other in the donor skin sample it is not advisable to separate them as it can cause iatrogenic damage to them. Advantage of this fact is taken to form three-and four-haired groupings when 2 two-haired follicular units or a three haired unit and one-haired unit are naturally placed very close to each other. A group (of 1-4 follicular units naturally placed close to each other) transplanted as a single graft results in superior hair growth and at the same time lessens the surgical damage and trauma to the recipient site.
