I've hunted high and low for a natural high colour and this one is great. I have black asian hair with grey - and not all colours stick. This didn't have any problems. I didn't apply to washed hair - but to clean dry hair (easier to handle, far less drips). I also didn't leave in for the full 30 mins - as had overcoloured hair before and didn't want to risk it. Came out dark, shiny and soft.
Have ordered again.
