The history of hair transplants dates back to the time of World War I. It was developed mainly in Japan and the USA. In the 50´s and 60´s it was further developed by the U.S. hair transplant dermatologist professor Dr. Normale Orentreichem.
Professor Dr. Orentreich in the U.S. initially transplanted skin grafts for up to 4 mm, which contained 10 to 20 hair follicles. This confirmed the fact that hair grafts, which transfer transplanted hair from one to part of the head to the affected area, grow and retain the characteristics of healthy growing hair and no longer succumb to androgenical lunge.
Early 80’s, the hair grafts are replaced by new mini-grafts and micro-grafts and this method was more successful. Today we use a hair transplant micro-grafts with 1 to 4 hairs.
A new method in hair transplants was called follicular unit transplantation or FUT - follicular unit transplant. It began to pursue in 1995 and was based on the new finding that human hair does not grow in isolation, but in groups. These groups contain 1 to 4 terminal hairs, 1 to 2 velus hair and their associated sebaceous glands - arrector musculum, drank, and neurovascular plexus perifolliculum that connective unit together. Transplant of follicular units allows us to achieve the result of natural hair growth. This also makes this method of hair transplant is currently the best.
Follicular Unit Transplant (FUT) is a method which can be transplanted in one procedure over several thousand grafts at once. This way you can achieve great hair density, natural looking result. This process therefore offsets a large number of follicular units.
The advantage of this method is that the hairs are transplanted in their natural forms "follicular units", consisting of hair micro-grafts of groups 1 to 4 hair. Pile groups that we called follicular units, are separated under a microscope and planted in a designated area on the head. The result follows by transplant of hair is indistinguishable from natural hair man.
The only possible drawback is a small thin scar that is visible when the hair is shorter than 5 mm.
The donor area should have a length of 10-20 cm and a width of about 1 cm. It depends mainly on the number of units needed for hair transplant. On average, you can get hair about 40 units per cm ², corresponding to 100-200 loss.
FUE method, "Follicular Unit Extraction" evolved from FUT method. From sampling areas in the occipital hair wreaths, which are all clipped before the procedure, small individual grafts are collected using a special needle -the follicular unit size is about 1 mm. This way the cut hair follicles are transplanted directly into the reception area. This method is very laborious and demanding with large losses. Root (follicle) damage may be collected from individual grafts simply because the direction of root growth is difficult to estimate. Very often they can get damaged and so the follicular units can be destroyed. Using this method we can remove and insert in one performance a maximum 700 grafts. This hair transplant method is suitable for minor procedures.
