Gold Thread Implantation Promotes Hair Growth in Humans and Mice

In a 2017 study, researchers discovered that gold thread implantation could effectively promote hair regrowth in both humans and mice. A 38-year-old female patient experienced increased hair growth 24 months after undergoing a facial lifting procedure that included gold thread implantation, without any hair growth medications. In mice, the implantation of gold threads resulted in a significant increase in the number of hair follicles by day 14 post-implantation, outperforming the results seen with a polyglycolic acid (PGA) thread group. Histological analysis showed stronger PCNA staining and higher collagen density in the skin of gold thread-implanted mice, indicating enhanced hair follicle development. The study, which included 19 mice per group, suggests that gold thread implantation could be a viable alternative therapy for hair loss, offering a potential substitute for FDA-approved drugs like finasteride and minoxidil, which can have adverse effects. However, further research is necessary to confirm the therapeutic mechanisms and assess long-term safety.
