I've been colouring my clients hair for several years and she has majirel 7 and 7.3 20vol (more than 70 % grey) but every winter she asks for blonde and red/copperish pieces through it, she has a short crop style. Last time I tried 7.44 as the red colour but to b honest you could barely notice it, it's always in back of my mind that tint doesn't lift tint x would i b better to go with a shade 6?? Or can u suggest another idea? Thanks any help appreciated x
