Unlike conventional hair color products that can leave your hair dry, brittle, and damaged, Natural Miya uses cutting-edge technology that quickly opens up the hair cuticles allowing for faster absorption of the hair colorant and vital nutrients. This results in longer-lasting hair color. While most hair color products use a chemically corrosive, “paint-style” coverage process that damages the hair. Natural Miya, the plant-based water-soluble ingredients that we use, naturally nourish the hair and scalp, leaving no chemical residues in or on the body. Combining the natural essences of soybean, ginseng, henna, vitamins, and wheat oil, Natural Miya leaves the hair thoroughly refreshed, hydrated, smooth, and shiny. It is odorless, leaves your scalp feeling clean, and makes even very sensitive skin feel great! Shampoo, dye and conditioning in one easy 10 minutes step, use 1packet a time.
