Hairdressers (or home colourers)- developer question.....
If we have any hairdressers or home colourers, can I ask a question? I am getting some colours online (no hairhouse warehouse close to me).
I have probably at least 50% grey hair - when colouring at home (box colours just not covering the greys these days), what % developer should I get for great grey coverage? I think it should be 20 vol or possibly 30 vol.
Help me if you can!!
