Which color type is described as oxidative coloration requiring a developer?

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

Answer: (D)

Oxidative color types rely on a developer to activate pigment molecules and lift the cuticle so color can deposit in the cortex. The phrase oxidative tints with ammonia fits this idea exactly because it names the oxidative chemistry and the ammonia-based activator that opens the cuticle and drives the color reaction. Temporary color sits on the surface and doesn’t involve an oxidative process with a developer. Demi-permanent color uses a small amount of developer and involves some oxidation but is not described by ammonia-containing oxidative tints in the same way. Permanent color also uses a developer, but the specific category that matches oxidative coloration requiring a developer and emphasizes the ammonia-activated process is the oxidative tints with ammonia.
