Are there any toners or blue shampoo that work on medium to darker hair? The only one I've found is Josh Wood gloss but it makes your hair reeeally dark (almost black) which is too ageing for me. It does tone away the red (it has green tones) but is way to dark. The lower half of my hair is brassy due to his total box dyes. My natural hair is cool medium to dark brown but the lower half is brassy reddish brown which doesn't suit me.
Is there a toner or shampoo that would work to retain the level of the hair as medium brown as opposed to making it darkest brown?
Thanks
