Looking for advice on hair colour. I’m mid 40s and greys are coming in thick and fast. Natural colour was a sort of chestnut brown, I’ve been having blonde highlights for over 20 years now, with an all over brown tint applied too now to cover the greys. I’m hating the blonde/brown/grey mix now and it’s getting to the point where I’m really needing colour done around every 3 weeks. I don’t want to be paying for colour that often. Should I go for an all over colour and stop the highlights? If so what colour, should I do it at home, and if so are there any recommended brands? I have green eyes and quite dark brows/lashes, fairish skin.
