@htav Welcome to you. They are right there are many threads on cold caps. This one comes to mind..
http://onlinenetwork.bcna.org.au/discussion/15635/cold-caps/p2It really depends on your Chemo regime if it will be successful or not, I've know people who have used them but to no success. My Oncologist warned against it as I had FEC (red devil) and with the hard hitting chemo it's generally not successful. Or quite a few abandon as did my friends as hair thinned too much they had to wear headwear anyway. M x
