For professional use only. When used at home, hair dyes can cause serious allergic reactions and can leave stains on the scalp, plastic, or absorbent materials and towels. Schwarzkopf Professional Igora Royal is the first cationic developer lotion with healing properties. Thanks to it, products for bleaching and coloring get a uniform creamy consistency. The components contained in the developer and paint mix easily and quickly, perfectly combining. The product guarantees the softness of the dye and an impeccable distribution over the hair, so that we get a gorgeous even shade from the roots to the tips. The developer has a low pH level, so it has a very delicate effect on the scalp without disturbing the acid-base level. The special cationic component of STAC gives the product conditioning and antistatic properties, making hair look shiny, smooth and healthy. There are several developer lotions that vary in intensity. All of them provide full and high-quality control over the process, guaranteeing excellent results.
