Grey/ green tinges

[traimai]

hi, i have had my hair coloured to a lovely grey, but i find it tends to go back to the blonde quite quickly, what can i put on to keep it grey for longer, ideally non damaging, and will purple shampoos make it look a little green? and again what can i use to cancel out green tinges..i was thinking directions as used it before when my hair was red..:-)

Purple shampoo shouldn't make it green, and it's the best way to get grey in my opinion. Just leave it on for a few minutes.

If it does give a slightly green tint, just add a tiny bit of pink directions dye so it's very pale pink and use that. The pink will do to the green what purple does to yellow.
