Which color category lasts through several washes and generally does not require oxidation?

• A. Temporary color
• B. Semi-permanent color
• C. Permanent color
• D. Glossing treatment

Answer: (A)

Understanding how long hair color lasts and whether oxidation is involved helps you match the service to the result you want. The color category that endures through several washes without needing oxidation uses direct dyes that sit on the surface and may lightly penetrate the outer layer. Because there’s no developer to open the cuticle and form new bonds inside the hair, the color fades gradually with washing but remains visible for multiple shampoos. This makes semi-permanent color a good option for trying a shade without the commitment of a permanent color. In contrast, temporary color sits on the surface and washes out quickly, usually after one wash or a few, while permanent color relies on an oxidative process to create lasting bonds inside the hair, and glossing treatments provide a short-term, shine-enhancing result.
