There are many factors that can cause hair loss. An increased sensitivity to hormones called androgens, especially dihydrotestosterone (DHT), is at its basis. In fact, androgenetic alopecia is caused by genetic sensitivity of hair follicles to this hormone. DHT causes a gradual shortening of the active stage of hair growth, causing thinning and ultimately hair loss. Hair transplantation is actually based on the fact that the follicles on the back of the head (donor site) are resistant to this hormone. Therefore, when a hair is transplanted from this region, it retains its properties, which means it is permanent and does not fall out. It is possible that androgenetic alopecia can be prevented if therapy is introduced early, while hair loss can certainly be slowed down. Nowadays, several important therapies are available, among which PRP therapy provided best results. However, hair transplantation remains the only safe and permanent solution for hair loss, being based on the fact that the donor site (back of the head) does not contain the 5alpha-reductase enzyme. Thus, transplanted hairs do not fall out. Hair transplantation is a procedure that takes several hours, depending on the size of the transplant. The technique used in the hospital S.tetik is “strip” technique, also called FUT procedure – follicular unit transplantation. Strip technique got its name because a strip of skin is harvested from the donor site. The excised strip is about 2 cm long and 10 to 15 cm wide and micro-grafts are taken from it. After the strip is excised, the skin is sewn in layers to make the scar less visible.
The second part of the intervention (graft implantation) is based on the same principles of successful and natural hair transplantation (natural direction of growth, arrangement of different grafts, appropriate hair density, etc.).
The intervention begins in the morning. The patients are advised to wash their hair in the morning and have breakfast. Prior to the intervention, the hair of the donor site is cut to 1-2 mm in length. The first stage involves extraction/harvesting of hair grafts. After induction of anesthesia, as the entire donor site becomes numb and painless, strips are harvested. Afterwards, the surgeon extracts each individual graft and arranges them as needed until implantation. If there are any damaged grafts, they are discarded immediately because these cannot be used. Depending on how much hair is needed, this stage can take up to four hours. In the second stage, the patient is lying down in the semi-supine position. After the last joint consultation on the new look of hair, the recipient site is anesthetized. A micro-surgical blade of 0.5-1.0 mm in diameter is used to make incisions-cuts angled as the existing hair, in a predetermined density and pattern, to promote a natural hair pattern once grafts are inserted in place. After this, the grafts are implanted by the team. This stage requires great precision and patience, which is why it takes a little longer than the first stage.
