Treatment of hair loss has become quite common in recent years. Gone are the days where the unsightly toupees were the only reprieve for the people with hair fall. Now you can benefit from the state of the art procedures that work like magic. The two most common procedures are the Follicular Unit Transplant (FUT) and Follicular Unit Extraction (FUE).
Any hair transplant discussion is much about the extraction and insertion of grafts. Many people are curious as to how it happens and how the new hair grows. Here is a quick look into the phenomenon.
Grafts are the follicular units that are inserted into the recipient sites for the purpose of new hair growth. These are patient’s own hair taken from the donor sites thorough processes we will discuss shortly.
The numbers of grafts needed in the hair transplant vary with the required density of new hair. The capability of the donor area is also important in this matter.
In FUT, a strip of scalp is cut generally from the back of the head. It is a linear cut and does leave a scar. The hair follicles taken this way are then cut into groups of one to four hair known as the follicular unit or graft under a stereo microscope. It is then left in saline water as more dissection is done so that it does not get damaged.
In FUE, a punch like mechanism takes out individual grafts with precision. It allows for lesser chance of grafts being damaged ahead of the actual transplant.
Making incisions is the last step before the grafts are inserted. Perpendicular incisions are made by the surgeon who uses specialized needles for this purpose. It is critical that these incisions are made properly and at the right angle as the growth of new hair will be in the direction based on these incisions.
The last step is to insert these grafts in the incisions at the recipient site. It’s along procedure as each graft has to be placed in an incision. Grafts containing three to four hairs are inserted in areas where volume is desired whereas areas that require a more delicate look get a single hair graft.
Once completed, the surgeon carefully examines the whole process to ensure that everything is in order.
