Which term describes permanent color?

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

Answer: (D)

Permanent color works through an oxidative process that uses an alkaline agent to lift the cuticle and an oxidizer to develop and embed pigment inside the cortex. When ammonia is present, the cuticle opens more readily, allowing dye molecules to penetrate, and the oxidizer then drives chemical reactions that create larger, stable pigment molecules that stay in the hair. That combination—oxidation plus an ammonia lift—produces lasting color, unlike direct dyes that just sit on the surface, or demi-permanent and temporary colors that don’t involve this full oxidation/deposition process.
