The best one is Hongchang's "Traceless Art Transplantation of Hat Hair Follicles". When extracting hair follicles, a special extraction technology is combined with a complete set of imported hair removal equipment, which greatly shortens the operation time and improves the extraction rate of hair follicles. The whole removal process is painless, no scar is left after operation, no hair follicle is lost, and the postoperative effect is excellent.
