i am cautiously optimistic, as i've only been using it on my temples and sides for about 2 months. i may be crazy, but over that time my sides seem to have thickened considerably. they were looking terrible just weeks ago, enough to make me feel like giving up, but now it's really hard to tell that they're thinning. granted, 2 months is way too premature to judge something. but i feel like my recession/thinning could be due to poor scalp health moreso than dht, and with the increased thickness i feel much less itching.
