I've just been using this one:
as far as the DHT blocker and Biotin shampoo goes, IDK. Seems like it would be more of a preventative maintenance type thing if you are going to experience an increase in DHT like I might with epiandro and dhea. I agree that it doesn't sound like it would improve hair growth, as much as help protect it, whereas the minoxidil "should" create some recovery if it's not too late...
that's my understanding. I'm throwing the kitchen sink at it and hoping for the best while simultaneously accepting that i'm 41 and it is what it is. the only thing that irks me is that there is zero male baldness on either sides of my family so that's why I felt inclined to try something.
