Hair transplant is a procedure which involves the transfer of grafts from the donor area to the recipient area. We can see that the balding pattern usually affects the front and the center of the head while the sides and the back show normal hair growth. The hair donor zone is generally marked out to be the sides and the back of the head. These zones are considered as safe as they show abundant hair growth due to DHT resistance. There is a scientific reason behind this phenomenon. DHT is actually a highly active form of androgen hormone which triggers genetic hair loss. The hair on the back and the sides are resistant to the effects of DHT. That’s why the males show balding in areas other than these. When the hair from these areas is transferred to the recipient area, it still remains DHT resistant. This feature lends the procedure the quality of permanency. So choosing the right donor zone is absolutely essential for the procedure to give the best and long lasting results.
Which is the safe zone?
As already discussed, the back and the sides of the scalp are known as safe donor zones. In the medical language, they are referred to as the occipital and parietal part of the scalp. These are resistant to the effect of DHT. While performing the procedure of hair transplant, the roots of the hair are extracted from the safe zone and grafted on the recipient zone. Doing this will ensure that the results of the hair transplant are permanent. FUT technique is generally used in hair transplant surgery. The roots are extracted and the scalp skin is closed using Trichophytic closure. After the extraction of the strip, the roots are separated by dissection done under the microscope. The roots are then implanted on the recipient area.
Significance of Safe donor Zone in the Hair Transplant Procedure
- Gives permanent results
- Gives high-density results
- The zone determines the grafts that will be required for complete restoration
- It is the best solution for all types of Norwood baldness, even if the grade is small or great.
- It occupies great importance in FUT transplant as it helps in giving the best possible results. It is only in case of DUPA (diffused un-pattern Androgenic alopecia) that it is rendered useless as it affects the roots of the safe donor zone as well.
Thus, we can conclude that deep research should be carried out before opting for the procedure.
