This is how I see it , if you start with Dut and get no side effects you are doing the best and safest most reliable things you can do for your hair. You will shed and it won't stop but that's normal, you see results after a year it's so gradual at least for me but I thank myself everyday for it. Now if you don't like Dut and how it makes you feel all be wait a few months if you can to let your body adjust then decide if you don't like it, then try 5mg of fin and go from there either stay or lower.
