I was also told by my hairdresser to take Biotin [i got it from our local Walmart, not expensive.] It's a vitamin supplement and I started taking it a month before my surgery and I haven't lost any hair. This was a big concern of mine because I have fine hair to begin with. I'm still taking the Biotin, as a matter of fact, I picked up a new bottle yesterday. It also helps your nails and skin. I have crappy nails and it seems to have strenghened them also. I highly recommend taking it, just let them know at the OCC to add it to your "daily meds list" when you go to have your surgery. Best wishes, Darlene
