Turned my hair from bright red back to my bleached blonde in one use. I have tried this product on blue hair too, but it only removed it a little bit (my hair went 1-2 shades lighter blue). But that was expected since blue is basically impossible to get out without a bleach bath. In love with this product, even though it doesn't have a pleasant smell.
