Found this from follicle thought. At least, this company is more transparent and professional than the Italian ones. Could be another disappointment / scam, but, yet another option is not bad at all cause we dont have much choice here. Mechanism: "The product itself is a stem cell-derived serum which has been tailored to be effective at preventing hair loss and stimulating hair growth. To do this, Medipost takes a specific type of stem cell called a mesenchymal stem cell or MSC. The MSCs are then subjected to an in vitro environment, in the laboratory, which mimics the biology of androgenic alopecia. The theory here is that by creating an artificial alopecia environment around these stem cells, they will react by secreting hair growth promoting factors or proteins to create balance. Medipost then collects these factors in what is referred to as a “stem cell conditioned medium” and puts that into a nice little bottle for you to use at home" Status: "To date, Medipost has conducted two clinical trials with NGF-574H and both resulted in successful outcomes. There is also another larger 6 month study planned which is set to begin this month in Korea. Note that this is an additional study and the NGF-574H product is already expected to launch in Korea in Q1 2019." So we may have official trials done by the company and non-official trials done the consumers.
