This is a link I stumbled upon a while ago, and have exchanged some info with it's host too. At first site this looks like all about hair, but when you look around, there's a lot of studies the author posted about a good deal of supplements he himself takes--you can also see his updated regimen.
Anyway, this is definately relevant to many of us males--I have vertex Androgentic allopecia--DHT was off the chart last time I had it done. By the way, I've been using a laser brush to good results--been using it for 6 months now every other day as recommended, and there's regrowth--the area is not covered with hair yet, but it's getting there. I got lots of new sprouts.
Further, there seems to be a few common factors about the processes affecting hair and other declining processes.
Look at the various studies he posted.
