I think 5 years could end up being an exageration, for a few reasons. One is that these scientists know the method is sound, and have had results in trials, so now it's just an all-out race to the finish. Two, I remember reading a remark by someone that said silence from the researchers could be better than big updates. Why? Because starting about five-six years ago we were hearing a lot from them, when the technology was in its baby stages, now, it's so close that any one breakthrough could solve it - so why would researchers want to offer updates that could help out their competition? The third reason is that although many people say "it will take this procedure X amount of time to pass FDA trials", not every country will have as strict regulations as the U.S. I think in a few years people will be able to have real hair multiplication done in Europe and other foreign countries at least.
