This stuff was so awesome. I have brown hair and used the red manic panic color. It looked so pretty and even. I went to a costume party over the weekend and everyone loved my hair. They thought I actually dyed it! Lol. I see people saying it doesn't cover much, and I could see that if you're using it by itself. I hair 2 feet of hair, it reaches my butt. I bought 3 bottles because of suggestions from reviewers. I ended up only needing 1/2 a bottle of this stuff to cover all of my hair. I mixed it as 2 parts leave in conditioner and 1 part hair color. It worked great! I left my hair up still wet that night and the next day, oh my gosh, it was so red!! I styled it before the party that night and it looked so pretty! I washed my hair afterwards and my hair completely washed out the red, which is what I was mostly worried about.So my tips to you, instead of buying 2-3 bottles, just mix it with leave in conditioner or similar hair product. It goes a looong way. Also just a heads up, if you touch your hair, your fingers will be the hair color. So try not to touch it. I was messing with my hair all day at school and work before the party and it looked like I was eating Cheetos all day :P Good luck and have fun with this!
