I Used this on my level 5/6 hair it's turns my hair to a level 1/2 nearly black/ dark brown Nothing like the colour at all extremely unhappy as I'm not having to spend more to put it right, I've washed it a few times in the hope that it will lighten to the colour its supposed to be but nothing seems to be working, I'm not worried I'm going to have to bleach my hair to get rid of the DARK colour.
