Length of time for Proscar to work + what happened to Dr Singh?

[Plan C]

I've been taking 1mg Proscar/day for 2 months and I'm still shedding. However, my hairline has continued to recede. Does anyone have any idea whether the Proscar simply isn't working or I need to wait for a longer period of time?

Also, I have a query about ukfinasteride. I noticed that Dr Singh recently stopped using ukfinasteride and when I asked why, I was informed that Dr Singh was no longer well enough to work. Does anyone have any futher information on this?
