I am considering starting with these, as suggested on this forum, so I have a few questions. These may be answered elsewhere, but I couldn't find the responses. I also thought it would be good to have all explanations on the same spot.
1) Is it true that finasteride is same as propecia? If so, is there any preference? Is there any brand that's supposed to be best?
2) Do I need doctor's perscription/check up to get these? Do I go to a general doctor or dermatologist, or something else?
3) How frequent, severe and permanent are the side effects? In other words, what fraction of users see side effects? How serious they are? Do they go away if the user stops taking them?
4) How effective it is? Does it only stop hair loss, or also promotes hair regrowth?
Thank you very much in advance.
