I have been using revivogen for the last 5-6 months but am approaching the end of the 3rd and final bottle. I am thinking about reordering but have noticed that it does not impress a lot of you out there. It is quite expensive so I am not sure about reordering if it is not going to do its job. Now, I won't be using propecia for one reason or another, so do you guys think it is better for me to reorder revivogen or go for something like xandrox, which contains azelaic acid and, according to Dr. Lee block DHT substantially. I have once used spironolactone before but felt it made my hair look very dull after each application, it seems to sap out all the moisture from the hair.
