The surgical restoration of hair allows the regrowth of hair from the area where it is lost via the hair transplant procedure. The hair transplant procedure is done either by the FUT technique or through the FUE extraction. In the context of hair transplantation, the donor part of the scalp that is also termed as the safest donor zone is basically the back and sides the scalp that contains the DHT resistant hair roots. The DHT or Di-Hydro Testosterone is actually a catalytic form of Androgen hormone that is concentrated in the scalp tissues. The DHT-hormone is responsible for the genetic cause of hair loss with the combined effect of the genes and hormone. Eventually, the DHT concentration in the scalp tissues causes the severe hair loss, miniaturization and baldness due to their loss sensitivity character. But, the hairs reside at the safe donor part of the scalp are extremely resistant to the effect of the DHT and remains forever on the scalp despite being transplanted onto another location on the scalp. The characteristic of the DHT resistivity of the scalp’s area has a prime value in the hair restoration world as it defines the permanent outcome of the procedure. The hair transplant cost is rated on the basis of the practiced technique and the role of the safe donor part cannot be ignored as it contains DHT-resistant hair roots.

The Safe Donor Zone of the scalp:

The occipital and parietal part of the scalp means the back and sides of the scalp is known as the safe donor zone because of its resistivity character towards the DHT effect. In the procedure of hair transplantation, only the safe roots are extracted in order to achieve the restoration goal of the surgery by the permanent graft/root implantation. However, the FUT technique is widely practiced to perform the restoration surgeries. The FUT hair transplant is the way of root extraction that follows the advanced closing technique, Trichophytic closure and a normal incision are made to excise the strip of the skin. The excised part of the strip contains the hair roots/graft are needed to separate by the dissection job performed under the higher magnification of microscopes. As a result, the FUT gives the permanent hair roots and also define the true meaning of the hair transplant procedure.

The Role of the Safe donor Zone in the Hair Transplant Procedure:

• It gives the permanent hair roots that lasted forever
• It makes the possibility of high-density hair transplant results
• The safe donor zone of the scalp actually defines the procedure of hair restoration by meeting the needed number of hair roots
• It is suitable for all categories of Norwood baldness, whether the grade is smaller or greater
• In reference to FUT hair transplant, it has prime importance, except the case of the DUPA (diffused un-pattern Androgenic alopecia) that affect the safe donor zone as well.

Thus, an in-depth research work is needed related to the procedure and one should apply both online and offline medium in order to know the relevant fact and information of the hair transplant procedure.
