Hair transplantation is the name given to the surgery performed for transplanting of hair. It is an effective alternative for restoring your lost hair. Hair transplant surgery has undergone considerable advancement in the last decade. The technique involved in the surgery has improved tremendously and new and better ways of grafting have been invented.
The procedure has received a shot in the arm by the introduction of large number of grafts in a small area and the transplantation of follicular units. Public awareness about this hair restoration procedure has also increased and this is supported by a spurt in the number of clinics that have opened up. These clinics have made this procedure quite accessible for those who can afford it.
Western world witnessed the first hair transplant procedure in late 1950 when Dr Orentreich, a dermatologist, started with the experiment of hair grafting. But after that surgeons were not able to successfully advance the research. In fact during 1980 to 1990, follicular unit transplant technique remained the preferred choice in which hair was transplanted exclusively in naturally occurring areas. In this procedure microscopic dissection of a donor piece was done and individual follicular units of 1-4 hair were relocated into minute punctures in the target area.
During the last decade hair transplant procedure has seen a lot of advancement. More emphasis was given to the angle and orientation of the transplanted grafts. This is a very delicate procedure and requires precision. So, a surgeon has to act like an artist to get the desired effect. It, therefore, becomes imperative to look for an experienced and deft surgeon who specializes in this procedure.
The latest advancement in hair transplant procedures has helped the surgeons to produce remarkable results; they are able to perform the procedure in limited time and with less dependability on the donors. What is most fascinating is the natural look that is restored after this. Of course, these procedures are not so easy to perform and require remarkable expertise. The new technique also comes with extra cost. Researchers made some attempt to automate the procedure but it was not successful as they had to compromise on the quality of the graft and also of the donor tissue.
These days the hair transplant is done in micro grafts and mini grafts. Micro grafts require grafting of 1-2 hair grafts while mini grafts need 3-4 hair grafts. This is a very significant advancement in the hair transplant procedure.
Patient has to be kept under intravenous sedation and local anesthesia is required to create occipital and supra orbital nerve blocks. A mild dose of epinephrine is given to reduce puffiness and temporary oedema. This is very beneficial advancement in hair transplantation technology.
