Practically, the most important risk of a hair transplant procedure is ‘failure’, as life-threatening risks are very little. Failure of a hair transplant may be, some or all of the transplanted hairs not growing, donor damage and depletion and an unnatural looking result. Fortunately, most of these risks can be controlled by experienced clinics, with the only exception of some of the grafts not taking, which requires a bit of help by the nature. The frequency of this complication must be low and the clinic must have an ethical policy in dealing with this situation. The incidence of grafts not taking at AEK Hair Clinic are very low and the patients are guaranteed that if this happens, a free touch-up procedure will be offered or even a refund.
