A client is seeking a hair color that will gradually fade with shampooing, deposit color without lightening their natural hair, and does not require a patch test. Which type of hair color best fits these criteria?
- ASemi-permanent hair color
- BTemporary hair color
- CPermanent hair color
- DDemi-permanent hair color
Show answer & explanationAnswer & explanation
Correct answer: B. Temporary hair color
Temporary hair colors only deposit color on the hair surface, wash out with shampoo, do not lighten natural hair, and typically do not require a patch test as they do not penetrate the cuticle or use developer.
Why the other options are wrong
- A. Semi-permanent hair color penetrates the hair shaft slightly more than temporary, lasts longer (4-6 shampoos), does not lighten, and typically does not require a patch test, but temporary is the best fit for 'gradually fade with shampooing' and definite no patch test.
- C. Permanent hair color requires a developer, lightens natural hair, provides long-lasting color, and always requires a patch test.
- D. Demi-permanent hair color uses a low-volume developer, deposits color, can slightly darken, but does not lighten, and usually requires a patch test.
Temporary Hair Color
Hair color products that coat the hair surface with color molecules, washing out easily with shampoo, do not require a developer, and do not lighten the natural hair color.
- Coats hair surface only
- Washes out with shampoo
- No developer required
- Does not lighten natural hair
- Generally no patch test needed
Memory trick: For a quick splash of color that washes away, temporary's the way.
