to make it short, most of the thing the salon advices you, sadly is useless for MPB.
as for Aminexil. it was out in the market around late 1990s. except for good internet "review", i have never read anything good about about it in forums for long over so many years. to me it a total waste of money. to make things worst, Loreal took picture from merck propecia website and pass it off as their own

during those days.
i did try it for a period of time. it was the same ingredient found in Spectral DNC. as for spectral DNC, the generally feeling is it is not much better then plain old minoxidil.
Edited:
Oh, and for the 130person study? it lasted 42days. someone could properly grow hair with lemon juice with the number of days.
