What is Hair Grafting?
Hair grafting is term used for the surgical transplantation of hairs; the process involves harvesting of healthy hair follicles and implanting them to the area where those follicles are not present. Whereas, a word “Graft” is a standardized term referring to the strip of skin with healthy hairs. A hair transplant expert can take grafts from any point on the subject’s body but most of the times occipital scalp (the zone found on posterior scalp) is preferred because of its high growth sustainability. Moreover, the size and shape of grafts is based on availability of technology, tools and applied surgical procedure. The procedure starts by forming hair graft by means of taking out the tissues from the donor site with an objective to transplant the healthy tissues to the site that isn’t able to grow hairs. The tissues removal process can be categorized in two methods that are,

When it comes about applying the FUT procedure, here grafts are harvested by the use of stereoscopic -dissection microscopes. The process is initiated by conserving follicular units and then those are set ready to be inserted into the recipient scalp. Each strip consists of 2-3+ hair follicular units normally and it is made sure by the physician to mark the incision of same dimension as that of the graft. Finally those grafts are placed into each incision, one by one at appropriate distance and direction, so that it could replicate the already present hairs.

In FUE, the only difference is that tissues are removed as individual units rather than removing the whole strip at once. Rest of the transplantation process remains the same as it is for FUT.

Survival ability of Grafts
During the transplant surgery, survival of hair grafts is prime motive but still there are few factors that can prevent the survival ability. Let’s take a look,

Several studies reveal that grafts can survive in a dry environment for about 16- minutes until they die. Therefore, it is suggested to keep them hydrated by using salt based liquid solution.

A temperature can also risk the survival of grafts, keeping them chilled can help.

A proper flow of Oxygen is also an important factor to keep grafts alive because when grafts a separated from the donor site, they are rundown by oxygen. If the availability of oxygen is low or if they don’t get the proper flow of oxygen for a longer period of time, the proper growth of those grafts can effect.
