I want to cover my greys. I have been using a box dye for years but colouring every 3-4 weeks is destroying my hair. I have a consultation next week with a hair dresser but I need something manageable. Do people go for foils/highlights every 12+ weeks and keep on top of greys by colouring the roots with a box dye? Have I made that up? No one does grey blending near me. I use a 7 box dye so it’s not too dark but I want healthier hair and can’t afford the hair dresser every time the greys show. How do people manage?
