I used this for the first time and was anxious as I'd used the same dye for over 10 years and it was no longer available. My hair has gone very grey and it has covered all my grey better than the brand I had used before. No unpleasant smell when applying it. The colour is darker than I expected but I'm getting used to it. My husband kept telling me how good it looked !! Very happy. This will be my regular colour now
