@yayapapaya I'd like to know specifically which pics you regard as a scam. Are you referring to the reddit guy from the OP?
If so, I don't get why you, who have been in these forums for years, do not understand the broad variability of human individuals regarding the response to a treatment. We not only observe variation in studies, but in this very forums. We always have seen a continuum of response for all mainstream treatments (minoxidil/finas) from absolute non-responders (the poor complaining souls who frequently dwell in these web forums) to unbelievable lucky freaks (check out the section of success stories).
Of course, this applies to every treatment and regime in human life. You can watch some guys subscribing to a gym and undergoing the same weightlifting regime and diet, and although most of them will gain muscle, some will still be skinny/chubby, others will bulk up and gain an enviable amount of muscle, while the majority of them will get average or moderate gains.
If you plot this kind of data into a graph, you will almost always find that most people will be clustered around an average value. As soon as you get away from the average value, the frecuency of observed people decreases (both poor responders and extremely good responders).
In statistics, this is what we call a Normal distribution. It is exactly what we are informally observing in this thread, as with the majority of phenomena in nature: most people are getting some regrowth, very few people (about 3 or 4) are saying they have No Results at all yet, and another minority (about 2 I think) are getting impressive results, almost on par with the OP.
Given this, it is fairly believable that the pics of the OP are legit, because he is one of the lucky ones of the right extreme of the normal distribution, a hyper responder. He is clearly away from the average value, away from us, average responders. Of course, as a normal distribution would dictate, people like him are a minority.
If you don't think that those pics are legit and that there couldn't be responders like him, then you would be implying that the response to a treatment should be Uniform, rather than normally distributed. In any king of treatments, uniform distributions are almost never observed, so such a tremendous claim from you should be supported by overwhelming evidence.
I partially agree with you in some points. There was some kind of hype and a bit of delusion at the start of this thread, because people were thinking that the results of the OP could be easily replicated (as if he was an average responders) and were seeing needlind as an absolute cure. Fortunately, the thread is more realist now and most of us know that this is just an additional weapon to fight hairloss. A good one. Most of us are aware we are not going to get our original full heads of hair, but we are believing it will get us to a considerable better state without having to worry about drug sides.
The thread has matured and will keep evolving.
