“I found this very good however a few things that need to be noted. I have blonde highlights. First attempt I left on for a few mins as it stained my hands I got scared! Washed off hands, not much diff to hair.
Next time I left it on 15 mins and my hair did turn purple and dried out my hair loads. 2 washes later and a strong conditioner later it was a lovely white blonde and soft.
So in short, stains your hands, will turn your hair purple and dry your hair out but I would buy it again. It’s not a dye so will wash out. Wear gloves and make sure you have a good conditioner at hand”
