new to this site so not sure where to post this question. I've got a client with a base 5/6 and a 50% root growth of grey hair. Do I use a 5 colour and a 3% to cover the grey. I have a 5.75 colour for her but not sure if that will do the trick. The root regrow the is about 1cm long.
Colour help please
