Hi Beardyweirdy, I have been on dutasteride for about 9 years now with good results. I switched from fin as I felt it wasn't working anymore. The dust has definitely slowed down progression of hairloss and I believe helped me hang on to my crown longer than I would have done without. When I compare photos before and after taking it with a 10 year timeframe, I can say in my case, it has helped me maintain more of my crown. It also gave me overall density increases. I have a UK source for dutastaride which are also at an excellent price. You have to complete an online prescription every time you order but even factoring this in, it is cheaper than any other suppliers I have found. I will private message you the website address. Regards, NTW
