Been on 0.5mg dutasteride every day for I think about 2 months now. Started taking it a few times a week on May 23rd, eventually upped it to every day. Basically I got 90 pills at the end of May and I just finished the last of that batch today. So technically I've been taking it for four months.
No sheds, no hair loss, no negative side effects. Hair's probably about the same. There's a big patch of those crappy bigger than velus\not real terminal hairs that I think is new and has sprouted on my left temple. Along the front of my hairline too, actually. Not cosmetically significant though.
Really hope to see improvement over the next 90 pills. If not, I might switch back to finasteride, just because it's supposedly "safer". I dunno...
