Hi Angie, I have used the cold cap for both sessions of chemo and it is a strange sensation but I have kept my hair. I have very fine hair but a lot of it which feels greasy if not washed frequently, so I wash my hair every day, but keep the water as cool as possible. I did cut my hair to shoulder length because of the matting in the longer hair. I have noticed slightly more hair loss than I normally experience but nobody outside those I have told seem aware that I have breast cancer so I think the dignicap is working. My chemo nurse says everyone is different and if this experience has taught me anything it is that you do what is right for you.
