Did not do much for my hair.I wanted to go from a lighter blonde to a darker blonde and this made for a complete hair disaster. I have ended up having to go brown, not happy as it made my hair look slightly green. Wouldn't recommend. I would like to note I seeked advice before purchasing the product from a qualified hairdresser who knows colour theory and who had did my hair previously so knew what colour I was prior.

Couldn't rate this high enough. My bleached highlights had made me hair so thin, I just needed to go back to natural and start again. I have light mousey brown hair, and this has blended in perfectly with my roots, which were 1-2 inches grown out. I didn't wack it straight on my head, I used my fingers to work from roots to end, focusing on the ends. I only left on for 10 minutes rather than the 20 it says. It has come out perfectly matching my roots. No stinging, no smell and shiny results even with no conditioner. I can now crack on with just letting it grow and thicken up again after all that bleaching. I would buy again. I can't comment on if it fades quickly but I don't think it will as bleached hair is more porous.
