Is it possible to use Special Mix 0/88 on it's own with a developer, say a pea size of colour with 100-120ml developer (1.9%)? I struggle to get my hair looking neutral/cool! Base level is 4-5 and has been bleached over the years. I've just bleached it about 0.5-1 level lighter, then used Colour Touch 8/81 (with 4%) a day later. Before pic is left, After pic is right - barely a difference! I know I have high porosity hair which doesn't always help. I've tried various shades of CT, Illumina and Koleston over the years but with little success.
