When I used a different color-correcting shampoo, I was a bit disappointed because it didn't really show the yellow tones being neutralized, but this one clearly shows the yellow tones being neutralized and turns into a beautiful gray color, which I absolutely love!! There's no staining on my hands, and the scent is really nice too! If you've bleached your hair light and want to dye it gray but are worried about the condition of your hair, I recommend using this product! Since it's a shampoo, there's no worry about damage, and if you want to put the gray back in after some time, you can just use it again, which is really great. If the bleaching is less effective or if there are parts at the roots, it might not take as well, so if you pay a bit more attention, I think you can use it beautifully without any streaks. Highly recommend!!🤍🤍
