I have natural brunette hair with some colour at the front (also brown) to cover the first few grey hairs. Ive now decided to go natural and grow out the colour.
I've read quite a bit about purple shampoo being used for grey hair to make it less yellow (I would quite like my grey strands to be as bright as possible) but I don't have that much grey right now....what would the impact be on my natural brunette hair?
