Review (5/5): The smell isn’t that bad!
I’ve been dying my hair “ultimate black” for about 4 months after having it dyed at the salon a lighter black a couple of months before that. I used this once and was back to my natural color with a little red tint. I’m super happy with the result especially since the alternative was bleaching. My hair is still super soft. My only complaint was when I received the product one of the bottles had burst open and squirted quite a bit all inside the box.
