Engineered Extracellular Vesicles for Tissue Repair and Regeneration

Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle 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.

The discussion is about using ASCEplus HRLB exosomes for hair loss treatment, which combines 10 billion exosomes with growth factors, nutrients, biotin, and copper tripeptide. The treatment is expensive and typically administered via scalp injections, but in Europe, it's done with microneedling.

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

Exosomes are being discussed as a potential hair loss treatment, with some users skeptical about their effectiveness and stability. There is interest in different types of exosomes, including those derived from centella asiatica, and comparisons are made to other treatments like finasteride.

Microneedling with exosomes is being considered for hair regrowth, but concerns exist about their effectiveness and safety, especially since exosomes degrade quickly and lack FDA approval. The user is seeking alternatives for non-responders to minoxidil and dutasteride, as exosomes may not provide additional benefits.

The conversation discusses new hair loss treatments like stem cell therapy, exosome treatments, and DHI, with mentions of GT20029, Amp303, and Plated PRP Serum as promising options. It also notes the use of dutasteride, topical finasteride, and minoxidil, but the focus is on non-hormonal innovations.
