A client with 25% gray hair desires a subtle, translucent color enhancement that will gradually fade over time without a noticeable line of demarcation. Which type of hair color product would be most suitable?
- ATemporary hair color
- BPermanent hair color
- CDemi-permanent hair color
- DMetallic hair color
Show answer & explanationAnswer & explanation
Correct answer: C. Demi-permanent hair color
Demi-permanent hair color is ideal for clients desiring a subtle color enhancement, blending gray, and a color that fades gradually without a harsh line of demarcation. It uses a low-volume developer and does not contain ammonia, so it cannot lighten natural hair.
Why the other options are wrong
- A. Temporary color washes out quickly and offers minimal gray blending.
- B. Permanent color provides full gray coverage and a permanent change, creating a line of demarcation.
- D. Metallic dyes are progressive, unpredictable, and generally not used in professional salons.
Demi-Permanent Hair Color
A hair color product that uses a low-volume peroxide developer but no ammonia. It penetrates the cuticle but does not lift the natural hair pigment, providing rich color, blending gray, and gradually fading without a harsh line of demarcation.
- No ammonia, low-volume developer
- Deposits color, does not lighten natural hair
- Blends up to 50% gray hair
- Fades gradually, no harsh line of demarcation
- Lasts 4-6 weeks, good for enhancing natural color
Memory trick: Permanent Stays, Demi Fades, Temporary Plays.
