The surgery is determined based on the patient’s medical history, donor site, recipient site conditions, patient’s lifestyle habits, current usage of drugs and expectations from the surgery. These things take one or two consultation sessions between the patient and surgeon to come to a fixed decision about the surgery.
Follicular Unit Transplantation is an invasive surgery which involves cutting out a strip of skin off the patient’s donor site, which is usually the back and sides of the scalp above the ears. The strip of skin containing numerous hair follicles is placed under a stereo microscope and very carefully the follicles with 1-5 hairs in one graft are carefully dissected from the skin strip and prepared and stored for transplant. Meanwhile the recipient site is created by the surgeon with hypodermic needles making tiny punctures to the recipient area. Once the recipient area is prepared the stored hair grafts are carefully inserted one by one. Surgeons strategically put the 1-2 hair grafts in the frontal area while reserve the 3-5 hair grafts for the center of the scalp to give a dense appearance.
This process is called strip harvesting that is the traditional hair transplant procedure, and the FUT hair transplant (http://www.hairtransplantclinic.org.uk/
Post surgery the patient will have a linear scar which is likely to be hidden in folds of hair and fade off in a month or two. Pain, swelling and bleeding for first couple of days post surgery is normal. For this reason you are always advised to choose a talented and compassionate surgeon who will give you a finer scar and ultimate care during your recovery. Full time recovery from the surgery takes a week and the scar to vanish takes maximum 2 months and final results a whole of 10-12 months to settle to.
Follicular Unit Extraction is a minimal invasive surgery that is carried out by individually extracting each follicular units and implanting it in the same way. Seeking patients are often quite attracted to this procedure than FUT because it leaves almost undetectable scars and a quicker and easier recovery post surgery. Moreover, with this procedure the surgeon can extract hair from the body also, with body hair follicular unit extraction (BHFUE) if there is limited donor hair.
However, it is a matter of fact that this procedure requires a larger donor area to extract the grafts than that needed for FUT. Given the fact that the donor site does not grow anymore hair since the follicles have been taken away from there, hence a smaller donor area is more wanted than less scarring. And FUE is more expensive than FUT given the strenuous work needed is also time consuming and might extend to 2 or more sessions for larger areas.
FUE is best when considering smaller areas of hair transplant and other areas like eyebrow transplants and patchy hair loss due to accidents or similar cases.
Given the whole idea, this is strongly advised to seeking patients to opt for a hair transplant surgery when at an advanced stage of hair loss than in the initial stages, because the androgen affected hair that is prone to fall, can't be saved with surgery and it would be a waste of cost, time and effort if you lose hair post surgery.
Shock loss is however, a normal side effect, which is when you lose hair after this surgery. This results as rather a post surgical reaction, which in most cases is a temporary loss and once after recovery the follicles would grow back the hair as is natural.
