i agree with sirchugalot, being a NW2 doesnt necessarily mean anything- for all we knpw you were a NW1 this time last year. anyway, with that said, i used revivogen for a month and then dumped it. why? partly out of my OCD tendencies when it comes to treating hair loss (i worried that the zinc in rev would interfere with minoxidil, ive since come to believe that i was in fact just being over-paranoid) but also cuz i realized that since my hair loss is obviously aggressive (diffuse NW2.5 @ 23 years) i dont have time to mess around, so i got on finasteride (been nearly 11 weeks now)
however, in that month of revivogen use, i gotta say i liked it. it took care of my male pattern baldness scalp itch for the most part, and just made my scalp feel gooood (one of the most soothing topicals ive ever used)
so anyway, if you think you have mild male pattern baldness, then why not give it a shot? again i agree with sirchugalot though, that you should probably incorporate some spironolactone into your routine (perhaps at the opposite end of the day, just to always have something working against the androgens)
also look up the "New Revivogen Formula" and Revivogen challenge or something or other thread around here, drhouse and browny say it seems to be helping...
good luck any which way
