Product Description A PPD-free, two-step hair dye system formulated for sensitive scalps. Instead of conventional oxidative dyes, color develops through an iron-based (Ferrous Sulfate) reaction — delivering rich, natural-looking color without p-Phenylenediamine or Parabens. Every shade is enriched with four traditional herbal extracts — Sophora Flavescens, Panax Ginseng Root, Paeonia Albiflora Root, and Green Tea Leaf — plus Camellia Japonica Seed Oil to condition hair during coloring. The set also includes a Herb Oil Shampoo blended with seven nourishing oils, including Coconut, Jojoba, Argan, and Avocado.
