I was very fortunate that @SoldierCrab and @Molly001 sent me stuff. I've also used scarves that I already had - just on my head now instead of around my neck and I've bought a couple of nice ones from Op Shops. Best type are wide and reasonably long or really large squares. You can make a nifty turban or have a gypsy look and co-ordinate with your wardrobe. One of my trademarks during this has been medical staff, etc wondering what I'm going to be wearing next. One of my chemo nurses regularly introduced herself as she didn't recognise me.
