Raczej własna, trzeba też dobrze zrywać strupki i w optymalnym czasie żeby nie powstały tzw. dołki w skórze. Nie wiem czy to w moim temacie pało pytanie odnośnie czy Demorsoy używa mikroskopu do badania donoru, ale tak czy inaczej dostałem info od Muzaffera: Dr.Demirsoy uses microscope during the surgery.After he extract he is looking to the grafts to see the quality.some grafts are all hairs same length. Some of them shorter hairs.in 1 graft if there are shorter hairs it means that this hairs are effected from dht.So he is checking how the donor area health is and from the view how it looks.if it's weak or strong hairs. After he extract he can see only which one is shorter.because it's roots which is under the skin. To predict it's mostly if he see on the donor area sparse areas than the other areas on the donor from there he can predict that a this small part of the donor area is effected from the Dht hormone.
