I had the same treatment as you are going to have and used the cold cap. As others have said it was uncomfortable for about 10 to 15 minutes and stretches out the treatment time, but for me it worked extremely well. My hair did thin out but not to the extent that I needed to wear anything on my head, in fact unless you knew me you couldn't really see much difference. It also grew back pretty quickly once the treatment was finished. I know everyone can have a different response but for me it was definitely worth doing.
