When using color-correcting shampoo to get rid of yellow tones, there are times when the hair can turn a khaki color. Since I really dislike khaki, I avoided using color correction until I went to a salon where they did it for me. When done lightly, it turns out a nice color like Cotori Beige. But I got greedy and wanted to get rid of the yellow tones completely, so I ended up purchasing both the daily shampoo and the silver color-correcting shampoo. Using the color-correcting shampoo really helped eliminate the yellow, and then using the daily shampoo afterward definitely helped reduce the khaki tones as well. I also think that compared to other color-correcting shampoos, there are definitely fewer stains. I plan to use the daily shampoo a little at a time until the color fades, and I think I can achieve Cotori Beige. For the first wash, I used the color-correcting shampoo once, and for the second, I used the color-correcting shampoo twice and the daily shampoo once. I adjusted the colors in the photos because the current color wasn't showing well. I didn't skimp on the shampoo; I applied it to the lighter bleached areas first and then added a little more product to the yellow parts while massaging it in. After rinsing, I finished with the daily shampoo. It says in the instructions that using a lot will definitely help with color correction, but it can also darken the hair. (I guess I won't need to dye it ash gray separately. Haha.)
