Good vs. Bad Shedding-what's the difference? Please Help

[hairgrass]

I've been on 1mg Propecia for over 10 months now (and 0.5 mg for five months before that). My problem is that my hair constantly sheds. Doesn't seem to ever stop. It makes me look like I have dandruff because each hair that sheds has the little white thing on the end (ok my hair terminology sucks). Point being, the shedding rarely lets up and makes me look like I have dandruff, and thus hurts my confidence.

Should I stop Propecia? I'm not sure if its helping or not. If it is, it's subtle.
I'm confused. I'm tempted to stop and just see what happens.

You should always shed at a roughly constant rate (100-300 hairs/day) and the hairs should have a white bulb at the end.
