Thanks for the quick response! I have 2 more questions: 1. Do I need to buy 2 seperate bottles and mix them myself (the black and dark ash brown), or can I order one bottle that you guys mix there? 2. Im concerned b/c you stated to only leave the color on the rest of my hair for 5 min. Is this long enough to really set in and make the color stay on and last ? I have brown hair with highlights, and even some gray in areas (not just on my roots). Im worried that I'll end up with really dark hair on top and lighter everywhere else. Thanks so much for walking me through this!!! (my first attempt to stray from the chemical laden products from most salons! ) Tez
