Poor you! I spent 30 years of my life with dark brown to black hair, spent 1 year blonde and when I returned to what was supposed to be mid brown I felt like a lego character with helmet hair. Never underestimate how miserable this can make you! I tried everything! Some people suggested washing up liquid but I tried the detox shampoos designed to strip hair of product build up. It did have some sort of effect, but you will need some time to get used to the look. Also wash hair twice a day with the detox shampoo and see how that helps speed the fading process. Good luck!!!!
