For those other hair geeks out there, I used - Directions 'Violet', Directions 'Carnation Pink' and Directions 'Pastel pink'.
I mixed the Violet with conditioner to dilute it and put it all over as a toner. I then mixed the Carnation and Pastel Pinks with Fudge 'Whiter Shade of Pale' to dilute then, and put the mix on the ends. I left it like this for 10 minutes, before massaging it all together on my head and leaving it for a further 10 minutes.
It lasts a few washes - I've already had to re-dye it, but I like the fact that it fades quickly!
