Which color type uses a developer as part of its chemistry?

• A. Demi-permanent color
• B. Permanent color
• C. Oxidative tints with ammonia
• D. Temporary color

Answer: (C)

Oxidative color systems rely on a developer to activate dye precursors and open the hair cuticle so color can form and deposit. The option describing oxidative tints with ammonia clearly signals this process: ammonia raises the pH to allow the color molecules to oxidize, and a developer (oxidizer) drives that reaction. This explicit combination of an oxidizing agent with an alkalizing agent is what makes the developer a core part of the chemistry in this color type. Temporary color sits on the surface and doesn’t involve oxidation, so it doesn’t use a developer; the wording here specifically points to the oxidative chemistry, which is why this is the best answer.
