Follicular Unit Extraction or FUE is the modern technique for Hair Transplantation. This technique uses a specialised extraction machine and the specialised doctor takes hair follicles from the donor area. Through this technique, units are implanted in the balding area and it works really well for small patches. The follicles are transferred to the required area using a surgical needle. The surgeon has to puncture the area of the scalp that has to receive the grafts. It might get uncomfortable due to the length of time it takes.
