For patients with severe androgenic alopecia, it is time to consider hair transplantation (autologous follicular transplantation). Hair follicles are individually extracted from the back of the head using a micro-electric device and transplanted to the hair loss area in the direction of hair growth in a single unit. Suitable for: people with large hair loss areas or those who seek perfection, single extracted hair follicles, no sutures to remove stitches, faster healing, no traces left, can go about 2500-3000 units at a time. The hair follicles transplanted in the past will continue to produce normal hair and achieve cosmetic results. However, patients after transplantation still need to apply the above introduced medication in combination to ensure that the hair on the original top of the head will not fall out again so that the transplanted effect can be maintained.
