It didn't last very long at all, and didn't really stay pink. I'd bleached my hair beforehand, it seemed to work at first but was very quick to fade and come out, so this might only work on very strongly bleached hair, probably not on natural tones of blondes even if they are light. I've since tried a different brand of dye and that has come out on my hair very vividly, and is still bright after a wash.

Would definitely recommend and use again!
