L’Oreal İnoa 5: Light Brown : I think it’s not light brown hair dye. Medium brown hair dye. You can use this if your hair is not dark brown hair dye. If your hair is dark hair becomes darker. 1,2,3,4,5 are the primary colors dye colors like natural hair. You can mix with different hair color, but I’m using one particularly hair dye number 5. Do not mix with different dyes. Already medium brown hair color. And my hair is closing this very nice white hair dye.
