Yes, the principle of scar implantation is the same as that of hair transplantation. Healthy hair follicles were extracted from the occipital part of the head, isolated and cultured, and planted in the scar area to improve the scar. The implanted hair can grow normally like normal hair, and the effect is lifelong. Before scar surgery, you should do a hair follicle test to see if there is blood circulation under your scar skin. If so, you can have a hair transplant. If not, you can't have an operation. Therefore, preoperative hair follicle detection is an essential step.
