Note: Follicular unit and graft is same.
Follicular unit extraction (FUE) is one of primary method of hair restoration. It is also known as follicular transfer (FT).
In this process individual follicular units are separated one by one directly from the scalp with the help of a motorised machine. The hand held unit of motorised machine is attached with micro punch that rotates at a high speed and makes a small circular incision around follicular unit. It thus separates the follicular units from rest of the skin. The follicular unit is pulled from the scalp, leaving behind a small open hole. This whole process is repeated until the surgeon extracts the desired number of follicular units. Once the follicular units are extracted, they are stored in suitable solution. The surgeon then transplants them in the required area with the help of needle, implanter or forceps. There are many variations of FUE based on some change in variables. In actual, every surgeon is trying to perfect the process, hence they keep on improvising and changing the process for better results.
Manual FUE: The scoring is done by a sharp punch (That is aided by finger movement of the surgeon).
Motorised FUE: It is the most common method. It is carried out with the help of a motorised FUE machine.
Robotic FUE: A robot is used to secure the graft.
Suction assisted FUE: A suction pressure is applied to the follicular unit after initial scoring. This is mainly for speed and transaction less extraction.
Direct FUE: The extraction and implantation are done simultaneously.
Bio FUE: The grafts are stored in a special growth serum and the same growth serum is injected with graft.
If you are updated about any new variant of FUE in any clinic apart from those mentioned above, it is simply a marketing gimmick to present to you that they are unique and have researched some new technique which is superior than any other technique. In short, it is a bluff
Local anaesthesia is used in all hair transplant procedure. Local anaesthesia means absence of sensation in specific parts of the body (such as a small part of the skin or tooth). During a hair transplant, anaesthesia is injected on an area of graft extraction, i.e. back of the head and area where grafts need to be transplanted (front part of the forehead). The first step is injections of local anaesthesia.
