Well I'm gonna see what happens. I still have a decent amount of hair although I receded in the front and have a small bald spot in the crown. The interesting thing is that I never shed or saw anything resembling regrow the with foam. I've been on the liquid for 5 weeks and I have experienced a slight shed, nothing major though. Also I have noticed peach fuzz in my temples and below my hair line. I never saw any of this on the foam. I'm wondering if PPG really makes a difference with absorption like some people say. I'll keep you guys updated with my progress as is is clearly way too early to notice anything significant. I'd really like to hear from others who started on foam and switched to the liquid. This is definitely interesting and a little exciting. I keep my hair really short so I am not affected by the greasy look so I apply it twice a day religiously. By the way, I've been on propecia for about 8 years but it doesn't seem to be working as well anymore
