The term for permanent color includes which of the following components?

• A. Ammonia-free dye
• B. Oxidative tints with ammonia
• C. Direct dye
• D. Semi-permanent glaze

Answer: (B)

Permanent color relies on an oxidative color system. It uses a dye precursor that must be oxidized by a developer, and an alkalizing agent to lift the cuticle so the color can penetrate into the cortex. Ammonia is a common alkalizer that helps open the cuticle and drive the color molecules in, making the result long-lasting. Direct dye deposits color without an oxidative reaction, so it isn’t permanent. Semi-permanent glaze sits on the surface and fades with washing, not a true permanent color. Ammonia-containing oxidative tints are the component that defines permanent color.
