Can anyone give me some advice or tips on which box colour dye might suit my hair. I've always thought of myself as having auburn hair but being honest its a boring light brown with quite a lot of grey. I've tried Garnier Olia gloss (cowboy copper) but my hair turned out rather "mauvy". I'd rather try a 24 wash one as I wash my hair everyday so if it turns out to be a disaster it will soon fade. Maybe going lighter might be a better idea.
Any tips gratefully received.
