I would never buy this product again!!!

Just used the 9.1 'viking' light ash blonde (I normally get their 9.0 natural light blonde excellence creme but could find it in several shops!). I knew there was a problem when after 30min I went to wash it out and the 'gel' had turned almost black!! My hair is now dark GREY and looks ridiculous, you have been warned!!!

Colour doesn't last

Used 10.21 STOCKHOLM very light pearl blond
It was a lovely colour after the first use, however, the colour doesn't last and in actual fact it has made my hair turn yellow.
As these were on special offer 2 for £12 so I decided to try it again but still the same result after the first wash the colour washes out.
I'll never use this product again
