I've been on 1mg finasteride a day for 3 days now, I know this basically no time at all but I thought finasteride lowered your DHT levels almost instantly? I thought this would then lead to the itch stopping basically straight away? Obviously I was wrong in this as it hasn't, it's nothing bad, I don't actually have to scratch it or anything, it's just annoying and almost like a constant "reminder" of what's going on..
