Hi Jesse, I did a test strand with Light Mountain for gray Auburn today. I have med. brown hair with grays. I put about 20 gray/white strands in with the rest of the brown and left it on for about 5 hours because i have coarse hair. The test strands came out black!! The step one came out a beautiful auburn color though. What should I do. I do not want black hair and i am so glad I did the test and not on my head i would have cried lol!!! How long did your mom leave hers on for? I know everyone is different but I was so surprised to see black.
