I read online that igora Royal -00 was supposed to be used with their 9% 30 vol developer however the hair Im doing is a Level 6 with some greys so I was intending to use 6% 20 vol with 5-00 as base colour but it’s thrown me seeing that the -00 colours are to be used with 30 vol. does anyone know which one is best to use?
