A new technique developed by scientists in Japan to reverse balding using hairfolliclecell transplants, and the discussion around the effectiveness of this approach compared to other treatments such as Minoxidil, finasteride, RU58841, Replicel, and Hairclone.
Hairfollicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
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.
Hairfollicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.
Microneedling with needle lengths of 1.5mm to 2.5mm to stimulate hairfollicle stem cells for potential hair growth. Using needles longer than 2.5mm is not recommended due to risk of puncturing veins in the scalp. A dermastamp is suggested over a roller.
