Studysummary This study found that Pep-1-mediated mitochondrial transplantation was as effective as PRP therapy in restoring hair loss related to aging in mice, with distinct improvements in hair and skin-related measures. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the effectiveness of platelet-rich plasma (PRP) therapy and mitochondrial transplantation in treating hair aging in 100-week-old mice. The mice received weekly injections of 200 µg of allogeneic mitochondria or human PRP for a month. Both treatments stimulated hair regrowth, but Pep-1-conjugated mitochondria (P-Mito) maintained hair length until day 28 and yielded more anagen follicles with abundant dermal collagen, similar to the PRP group. P-Mito also increased the thickness of subcutaneous fat compared to the control and PRP groups. The study concluded that P-Mito treatment was as effective as PRP treatment in reducing aging-associated gene markers and increasing antiaging Klotho gene expression, suggesting mitochondrial therapy could be effective in restoring aging-related hair loss.
