What is the difference between 3% and 1.8%- The main difference is the intensity of the result: the 3% developer provides a bolder, deeper, and longer-lasting stain, ideal for coarse hairs, while the 1.8% developer offers a softer, more natural, and gentle stain suitable for sensitive skin, lighter results, or post-lamination treatments.Both activate the dye, but the higher percentage of hydrogen peroxide in the 3% developer creates a more powerful and faster result.
