Mix medium ash brown and dark ash brown with equal parts developer. Be sure to always apply the color full strength to the roots only(equal parts color and developer). If you want to repigmentize the ends, ALWAYS use the remaining color mixture diluted by HALF with distilled water on the ends for the last 5 minutes of processing time. Make sure you allow the roots to process for 30-45 minutes. ALSO Be sure to use a shampoo that is sodium lauryl sulfate free..or sodium free or sulfate free.Also stay away from tea tree, camomile and castille in shampoos.
