How to wash your hair two days before dyeing it darker
Well, to be honest, there’s not much of a mystery about how to wash your hair before coloring it. Actually, you can use your regular shampoo and conditioner.
But this is important. After washing your hair, don’t apply any oils, styling creams, or sprays.
Why not? Because your hair must be free of residues of any type of hair product before you can dye it darker. If any residue remains, the dye may not set and the color will turn out uneven.
