Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hairfollicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.
PP405, a topical LDH inhibitor, has shown to stimulate hairfollicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.
A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hairfollicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
NMN shows promise in promoting hair growth by reducing oxidative stress and weakening androgens. It may be a beneficial addition to hair loss treatments like Minoxidil and Finasteride.
PP405 may damage hairfollicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
