The number of hair follicles collected in 1 session varies in hair transplantation process methods. In the FUT method, since the roots are taken and transplanted collectively, it is usually a single session and 2.000 – 2.500 grafts can be planted. In the SAPPHIRE FUE technique, the roots are taken and transplanted one by one, so it is a longer procedure than the FUT method. It can take an average of 4 -7 hours. The number of grafts taken in a single session is around 3.000 – 6.000.
