Thanks and best!!
I know lots of guys will disagree, but I don't believe Propecia or Avodart cause you to shed. It is common for us to force ourselves to believe that a recent surge of hairloss is a shed because it is easier to deal with mentally. In fact and unfortunately it is just hair loss.
I never 'shed' on avodart. I did continue to lose some hair over the past 6 years but I would be completely bald today if it weren't for it (and of course my HT's).
Personally Ive read that the second drug you mention is quite potent, so would take one or the other, but not both together. You dont want to get sick for the sake of vanity. Or atleast maybe start with say half a dosage of each for example and build up the dosage. Best to ask your Dr for advice.
