I understand where you're coming from jarjar, yes, it's a pretty big distinction, but Norwood3 has a serious point. There are also big parallels between the two treatments. I think this is a better approach than PRP, but still it's just taking cells out of one part of your body, and injecting them into the scalp -- as Norwood3 mentioned, without selecting for or multiplying stem cells.
I think people get overly excited about treatments like Kerastem. Inevitably, in the British tabloid press and elsewhere, we see these developments hailed as potential "cures" (they always use that word.) But, they are just incremental developments, and rather small ones at that.
I think people are confusing "necessary" with "sufficient". Kerastem, with its injection of fat tissue, may be providing growth factors necessary for hair growth, but not sufficient to regrow a lot of hair in the vast majority of people with MPB. They're touting this as a treatment aimed at both women and men, but primarily targeted at women. Hmmm... I wonder why. Probably because women tend to suffer from much milder hair loss than men with MPB. But, even on the women tested as shown in the photographs, improvements are pretty minimal. Hmmmm... I wonder if what they're selling here isn't just one more in a long line of marginal treatments.
Just because a Yale study says that "all the growth factors you need for hair growth are in fat tissue" or ADSC's, doesn't mean that this can cure you of MPB. All the growth factors needed to grow hair are definitely in there, for sure -- but that's assuming that the subject is genetically healthy and not suffering from MPB. MPB is more than just an incremental removal of growth factors. It's a pervasive and chronic depletion of activated stem cells (the stem cells remain, but they don't go into active mode), and a progressive destruction of follicles. You can restore all the necessary growth factors, and maybe grow a bit of hair, but it won't necessarily cure you, because your HF stem cells and DP cells are still seriously being suppressed by an "outside" force -- DHT. Restoring growth factors is necessary for hair growth, but it may not be sufficient to do much in people with advanced MPB.
I think Kerastem will turn out to be a marginal treatment. Bottom line, the things it is providing are "necessary but not sufficient" to fix your hair loss problem. We shouldn't get "necessary" confused with "sufficient".
