Actually that is false, strength training cause increase of testosterone. Which is good for a majority of reasons but one, that is hairless. More testosterone leads to more DHT, hence more hair loss.
I turned 20 this June and I had absolutely no excitement of turning 20 because I look like fucking 28. I have had hair loss since I was about 17 and from few hair strands caught in my between my fingers while playing with my hair in the classroom to huge semi-circles on both sides of my temple has rendered me helpless. I used to be very confident but now when I look in the mirror, I do not see my MYSELF. I see some aging looser. I am thinking of getting a hair system.
