Thanks @Sister. My oncologist told me about cold caps and that it can be time consuming and doesn't always work that well. I will look more into whether I want to try it. I have booked into a Look Good Feel Better course in September, and I am looking forward to that (I have actually never been that good at styling my hair or putting on makeup).
My mum told me about a place her friend went to where they have wigs and other products for people with cancer and we are going to check it out together. There was also a lot of useful information about services in Canberra at the Canberra Hospital which I took home with me after my appointment last week.
