Hi there! I didn't have time before starting chemo to cut my hair, so just left it (shoulder length). The nurses all said to avoid washing it at all if I could - so I didn't use shampoo (just rinsed in cold water every week or so) - after the first 3 or 4 weeks, your hair just balances itself and looks fine. The only hair I lost was from one week where the cap wasn't fitted properly (lost a very small patch on the top of my head), so definitely agree that you need to speak up if you can feel that it isn't tightly fitted. I took Panadol about 20 mins before the cold cap went on. The first 20-30 minutes are unpleasant (think: ice cream headache) but definitely persevere. I managed to get through the entire treatment without anyone noticing any hair loss and that was my goal. Good luck with your treatment!
