The colour is vibrant on the area where I put the developer which was on the greys. So the colour was vibrant at the roots. The colour was uneven. I have washed it once since dying. I like the uneven colour and the colour has reduced on the roots. The developer really works well but I think it would have been a more even colour if I didn't put the developer on the greys, but the colour wouldn't have been as vibrant as there is not much colour on the rest of the hair, which was a coloured dark blonde. The kit and hair products were easy to use. I have medium length hair, it's curly but thin so I had a lot of product left, about half, so a waste. would have been good if they came in bottles like previous products I have used and I use just the amount I need.
