Feel like dutasteride is over-hyped. My hair shed after taking duta was nuts. I took it for 3 months after 2.5 years on finasteride. No side effects on finasteride. Initial huge increase in sex drive on duta then a complete reversal and ED and low sex drive 2.5 months in. Had to quit ar inhibitors for a month after to reverse the sides and my hair is way worse than before. You could say the 1 month off ar inhibitors caused the loss but given the long half life of duta my dht levels should have actually still been much lower a month off duta after taking it for 3 months than when on finasteride alone. Feel like testerone causes hair loss for a lot of people not dht.
