Experiences with Docetaxel, Herceptin, and Perjeta

Thanks to everyone  - there is a lot to research and look into. I am going to have the ice/cold cap (not sure which system). How have people gone with using that? One of life's ironies is that I still have my hair plaits that my mother insisted I keep when I had my hair cut when I was 12-- they are now 48 years old! Not sure if they are too old to use for a wig????
I have medium long hair and my daughter suggested that I have it cut short to start with -- did anyone else do that?
