I am blonde and I bought the 9.1 to cover the white. My hair turned out gray-brown. I don't know why, but I was disappointed. It left my hair very soft but it has a very strong scent.

I used it a few months ago on my sister who has slightly lighter hair than me, afraid that it might turn orange on me. (my sister is the guinea pig) No relation, it lightened at least 4 shades. It needed one more application to lighten and become completely blonde, but I couldn't wait with the first platinum, it does what it promises and soon I will use it myself to share impressions.

EDIT 13/1: I also used it, although I forgot to inform, and it lightened the natural part of my hair from almost black brown to honey. It won't make such a big change on dyed hair unfortunately

I am already blonde with white hair in the front at the roots, but due to natural sunlight and the hair salon, I ended up having 4-5 different colors in my hair. It gave a uniform and stable color with a lot of shine throughout my head. Maybe the coverage on the white hair is not absolute, but it doesn't matter. Easy application.

I have used it on bleached blonde hair twice because I thought I was doing something wrong, but this color has no coverage at all and it is not intense at all, it's like I never applied it

Old-fashioned dye. My mother wanted it for her hair. She is 77 years old and her hair is completely white. This color works for her and does the job.

Due to the quarantine, I decided to try these hair dyes as I couldn't go to the hair salon. The 6.46 along with 7.43 (on the roots because I have jet black hair) gave a wonderful deep warm copper color that reddens just enough to not look orange or brown.

Although the color turned out good, it did not cover my white spots well. It only covered them slightly, and they are still visible in the light. Unfortunately, I was not satisfied
