During my relaxer years, I would get micro braids periodically over a few years. While I had the micros, I would use this thick anti itch oil that was supposed to keep dandruff away. I would shampoo every week or two with diluted shampoo. When I took my braids out, I went to my hairstylist to get relaxed since it had been few months. She put that relaxer in and as it combined with the anti itch oil it formed a paste that she couldn't remove. It was horrible. After about 4 or 5 shampoos (and serious prayer) the mix finally came out. Whew! That was the worst!
