Definitely a toning product! I've tried a lot of color shampoos to get silver hair, but nothing works as effectively as this one. It seems like it's a toning shampoo, and the color payoff is amazing. I bought it when my hair was almost yellow, and after just one use, it turned gray quickly, and after several uses, it got closer to a silver-blue shade.
One downside that can't be overlooked is... the scent is a bit off. It's not unbearable, but it has a somewhat strange smell that falls somewhere between bad odor and fragrance. However, if the results are like this, I would be willing to use it a hundred times more.
I didn't take comparison photos of my hair color; I edited the closest photo I had to show the actual color before and after. I had been putting off managing the yellow tones, but now that it's yellow, I feel like this isn't right! I recommend it to anyone who wants to quickly banish yellow tones!
