luvmylocs, I'm taking Viviscal too. Haven't noticed an improvement to my brows or lashes yet, but I will be hopeful now that you mentioned it.

I have seen and felt an improvement in my hair though. Reduced shedding and my hair is looking and feeling a bit fuller. It's been about 6 weeks using Viviscal for me.

Back to brows...I get mine threaded. More precise than waxing, IME, so I don't lose more in thickness than I want to. I have Carprost but I can't seem to remember to use it every night anymore. In the beginning when I was more diligent with it, it did seem to help. Now I am back to a few flicks of brow pencil to fill in sparse areas.
