The right hair transplant procedure to opt for might be the most common words of how the question is put and the answer to this is much obvious too. That is, that both the FUT and FUE hair transplant procedures are good and it is the matter of the patient's condition on which suits whom. Both are right, and either can wrong, depending on the patient's hair loss syndrome.
First up, let's talk about FUT.  Follicular Unit Transplant is the invasive option of the two, wherein a strip of skin containing a much healthy baldness resistant hair of evened quality is removed from the back of the scalp and then the skin strip is put under a stereo microscope where the follicular units are dissected or separated from the skin strip identifying the naturally occurring 2, 3, 4 and hair follicular units and dissecting them along with a little fatty tissue, which holds or binds the hair follicles together, much like how a sapling would be unearthed to planting at a different zone. The whole thing of the hair follicular unit wrapped in the skin tissue is called a hair follicular graft or simply grafts. And while the graft dissection was happening at the back of the lab by the assistants, the hair transplant surgeon would be almost done preparing the recipient site. The bald area of the scalp is called is called the recipient zone where the hair transplant surgeon would make tiny slits to which the hair grafts will be implanted. And just like that with a forceps the tiny hair grafts are planted to the recipient area one at a time, along the pre-marked pattern that is to the credit of the hair transplant surgeon's artistry, which makes the final results look more fuller looking hair.
Now the FUE hair transplantation differs in the way the donor hair is extracted. While FUT cuts a strip of skin to harvest the donor hair, FUE harvests the donor hair directly from the donor zone. The donor area is shaved and the 2,3,4 and 5 hair groups identified under magnified view and thence it is extracted using specially designed forceps and punches that makes hole around the follicular units and plucks the a whole graft directly from the scalp. The hair grafts are further cut to perfection under a stereo microscope and planting of the grafts are same as FUT technique.

Now the question is which to choose?
•    With FUT, this kind of an invasive surgery might be appropriate if the patient has good scalp laxity. As long as a good and high class hair transplant clinic/surgeon is consulted, the patient would probably not feel a thing during surgery, but pain, discomfort and swelling is a obvious reaction of both FUT and FUE hair transplant.

•    Hair Transplant cost is another factor, FUE hair transplant cost London is more   

•    While a whole surgery of more than 2000graftign can be covered under one session of 6-7hours with FUT, for a FUE hair restoration exceeding 1200 grafts might require upto 3sittings of 10hours each.  

If the patient has prominent and good donor density then the FUT hair restoration is ideal to get it over with under one sitting and at a lesser hair transplant cost. However, the lesser price should not be prioritized, since a 2cm skin will be stripped off the patient's scalp, the patient must have positive scalp laxity to close the wound and proper healing. FUE is ideal to consider when the requirements of FUT are not fully met, and the patient has a brick thick wallet to spare as up to £ 10, 000 as their FUE hair restoration cost.
