I love this hair colour. The colour is nice and rich, it lasts well. It doesn't have the overpowering odour of other dyes. I have found other natural brands leave an oily build up after a while but this has no build up. Its is also fast and fairly easy. There's only one minor issue that I have which is preference and not enough to remove a star is that the colour in the tube is a thick paste and developer a liquid. It can be hard to get ratios right if mixing and slow to combine, a bit easier if both were liquid. Still love this product, so quick and easy. Great on the greys!
