1) if you have increased itching, burning, crawling, etc... on finasteride, then it's not f*****g working. basic logic. NO drug that's supposed to STOP hair loss should inflame the scalp.
2) if after 6-9 months your hair is noticeably thinner, then it's not working. "shedding phase" my ***.
I watched my crown / midscalp get almost completely obliterated throughout my 12 months on finasteride. it's over a year after quitting the garbage and none of it has grown back. FINALLY, after about a year, the crawling / tingling, pulsing heart beat in my scalp is slowing, but who the hell knows.
People need to REALLY REALLY consider that the "studies" on Propecia may not be as accurate as we assume. The drug is complete f*****g garbage for A LOT of people. just read through all the threads.
