A new hair loss treatment using dermalexosomes can restore up to 90% of lost hair in mice. Users discuss potential human trials and compare it to Minoxidil and Finasteride.
Japanese scientists discovered ABM cells, enabling successful human hairfollicle cloning, potentially curing hair loss. The treatment may be available in Japan by 2028, but it will be expensive and require travel.
PP405 is the most promising future treatment for hair loss, aiming to reactivate dormant hairfollicles. Clascoterone 5% is the most promising near-term drug, while current strategies include using finasteride or dutasteride to stabilize hair loss and minoxidil to stimulate growth.
A new serum claims to enhance hair regrowth by amplifying oxygen delivery, improving the effectiveness of treatments like exosomes and peptides. Users are skeptical, questioning its efficacy compared to established treatments like Minoxidil and Finasteride.
This study found that dermalpapilla cell-derived exosomes promote hairfollicle regeneration during wound healing by enhancing fibroblast activity and activating the Wnt/β-catenin signaling pathway in mice.

This study suggests that exosomes from dermalpapilla cells can regulate hairfollicle stem cell proliferation via the Wnt3a/β-catenin signaling pathway, potentially informing treatment for human hair problems.
In this study, researchers found that dermalpapilla cell exosomes can enhance hairfollicle stem cell proliferation and reduce apoptosis through the Wnt3a/β-catenin signaling pathway, offering insights for potential hair problem treatments.

This study found that decorin treatment significantly enhances dermalpapilla cell proliferation, promoting hairfollicle growth by influencing the SMAD3/TGF-β signaling pathway through exosomal miR-129–2-3p, which may aid in novel strategies for treating hair disorders and enhancing wool production.

How does SCUBE3 work on hairfollicles compared to treatments like minoxidil or finasteride?Laboratory research in mice reports that SCUBE3, a protein released by dermal papilla cells, signals dormant follicles to grow through the TGF-β pathway downstream of Hedgehog; minoxidil and finasteride instead work on blood flow to the follicle and on DHT, and unlike SCUBE3 they have decades of human trial data behind them. SCUBE3 has not been tested in human clinical trials and is not available as a medicine.
What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth?PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
