Hairloss PI

Ok, so I have suffered from hair loss now for 3 years (31 now and strated notocing my hair was getting thin 3 years ago). I started on propecia 6 months ago (the only product I use for hairloss) and I experienced the dreaded shedding.

I thought I would stick to it and it would pass. Now it has been 6 months and the shedding just continues. Everytime I pull my hair for about a minute or two I easily get 40-50 hairs in my bathroom sink. Is this really normal? Why wont the shedding stop?

I dont know if I want to continue but alot of people here and on other forums say it will get better but my hair is getting thinner and thinner.

Last month I cut my hair and my hair looked fine short. This time short is not even working, it seems like the last month I have thinned so much that I can see my scalp in the front (hairline) and the crown.

The hairloss was never so aggressive before I started propecia 6 months ago. What is going on here? My doctor says he does not have an answer. I have one more week of dosage and need to decide if I want to continue for another 3 months. So far I have only shed and lost tons of ground.

What should I do, right now I'm so confused??
