I haven't had Docataxel but I believe that it's extremely hard on the hair follicles. I had AC and did the cold cap for the first two treatments. I gave up when I developed a bald stripe across my head that I couldn't hide. I then lost most, but not all of my hair over the next 2 treatments. If it's offered, I would advise to give it a go. Find out if there's an extra cost associated with it and if there would be any difficulty in stopping if you change your mind. It does make the treatment much longer and the intense cold can be painful although you should be offered Panadol. I was also given one of those electric doonas. You have to make sure that it fits snugly to your whole scalp throughout the process.
