The color used in the hair color shampoo should be water soluble or oil soluble. 2. Can I use hydrogen peroxide if I don't use it, or is there another option to bleach my hair before dyeing? every product what function Can we use another one? - Sodium Sulfite - Sodium Erythorbate - Sodium Stunnate Thank you very much for your advice.
