I actually had only a very slight wave until puberty, but I always wanted curly hair, so at the end of the 8th grade I decided to give myself a perm at home. Lol, bad idea. I decided to let it grow out even though I hated my not quite wavy natural hair. To my disbelief, it grew in very wavy/curly! (2b/c/3a). Of course, my parents did were not quite as happy because they thought I did another perm, lol. So for the next 3 years I had to try to convince them that the curls were real.
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!
