Pre-op, I had read here about a product that you can comb through your hair to clean it in lieu of a shampoo. I sent my husband all over the hospital in search of it, which he was finally able to locate. But be warned: IT DOES NOT WORK ON LONG HAIR! Post-op, I kept my hair pulled up in a valley girl explosion on top of my head with a scrunchee for most of the time but the dirty hair was one of the things that bugged me the most post-op (aside from the pain of course). That's when I found out that other stuff does not work well for long hair. If/when I have another AVR, I'm going to cut my hair much shorter, because post-op I lost LOTS of it anyway (either from the surgery or the post-op meds) and it had to grow back in anyway.
