Has anyone used a good home hair dye, I'm only looking for one of the ones that lasts 6wks, that covers grey and gives a nice rich colour. I've got brown hair, so will stick to dark colours but maybe with a bit of red in, as it will only last 6 weeks if I don't like it. I've got a few grey hairs growing now, which I'm not happy about and need to get them covered up!! I like to use products that other people recommend if poss. as it's usually safer.
