I just began taking 0.5mg Propecia this week. It was a decision of mine because I was a bit paranoid of the side effects and figured I would start halfway and at least save my hair. My plan is to increase to 1mg at 4-5 months. Is there any danger to this transition, like increased likeliness of a shed after going to 1 mg?
There is no problem with this approach, but I can not understand your doing it. I would understand if you got negative sexual side effects, which is 1 in a hundred chance. The full dose is the way to go for best results.
