I've been using Daniel Fields water colour on my hair. Whilst I really like it, I find that the grey coverage isn't great - within a week it's back.
My hair is curly and dry (I'm post menopausal) and not improving in this respect, probably because more grey is coming through - if I didn't dye it, I'd probably be completely grey quite quickly.
So - any recommendations for a non harming semi that does better grey coverage?
