Works great for medium brown hair! Definitely be thorough with it.

I realize there are a lot of mixed reviews for this product but it worked fantastically for me. My natural hair color is a medium brown and it worked excellently. My best tip would be to definitely over-do it to be safe. I don't use a brush with it, I just took globs and worked it into every inch of my hair and roots thoroughly. Basically rub it in like you would shampoo for like 15 minutes. Then, put on your shower cap and use your hair dryer on it for a few minutes. On the outside & sneak some inside so it can kind of "steam" in there. I left it in longer than suggested, about 50 minutes versus 30.
It turned out perfectly jet black and I was very pleased. For me, I actually didn't want it to last very long so I showered a few days later and shampooed 3 times. I can already see the tint of brown coming back which is definitely what I want. If you want it to last longer, definitely be more conservative with how often/thoroughly you wash your hair. I've used other manic panic colors in the past with that mentality and they last more as promised.
