I use majirel 6.1 with 20 vol developer mainly to cover greys. I like the colour. However, in the sun, the colour lifts and turns quite brassy. I normally only do my roots, so the length is turning quite orange now. I know I could do the whole length of the hair, but I’m worried adding more dye/developer will damage the hair and also lighten it more quickly on the sun. Can I mix majirel with conditioner and apply that all over so there is no more bleaching effect? I hope I’m not rambling too much. Thanks
