I've only been CG for about 4 weeks now, but something I learned early was to truly treat the co-wash like shampoo. Really work it in, getting your scalp and hair clean, and rinse it all the way out. I didn't rinse it enough at the beginning, and had a terrible weekend that almost made me quit! But I happy to say that since co-washing properly, I am much happier, and plan to stick with it! Good luck!
