I bought 2 boxes of Berina Hair dye in A21, which is light silver/grey. Firstly, the product comes with enough dye to actually cover quite a bit of hair, unlike other dyes. It went on very creamy and thick. It turned out as a pastel blue colour, not so much silver, but it dyed basically all my hair and faded out to a more silvery light blue. The only thing that was annoying, is that the peroxide it comes with, is 9%, so if you have any roots or regrowth, it will slightly lighten it and make it very brassy. Other than that, its affordable and lasted a very long time. I actually had to bleach the colour out to change it
