When my hair started falling out, I started taking the Biotin like you have, but I also started using Nutri-Ox Thinning Hair system, a series of shampoo, conditioner, and hair regrowth formula, I found at Sally's Beauty Supply. I also adjusted my supplement schedule to make sure my iron intake wasn't being impacted by coffee, tea, and cocoa (I had no idea those could block iron absorption!). The hair loss started at 4 months post-op, and I just entered month 9 and can definitely tell that not as much hair is falling out. There will still be some that comes out, but it's no longer a scary sight at my shower drain!
