@DoctorHouse - hairdx would be great if it was still available, but I think at the price it would have been an expensive way to confirm what I already know - I'm balding (and it's in my genes).
One thing that would have been very interesting though is their probability of being a responder to finasteride. What do you think they were tapping into to produce such a probability?
Also I saw a post of yours from 2010 saying you wouldn't try RU because it's not regulated. Has your opinion on that changed since so many more people have been using it now?
