A client desires a hair coloring service that will deposit color but not lighten their natural hair color, and will fade gradually over several shampoos. Which type of hair color product would be most appropriate for this client?
- ABleach (Lightener)
- BDemi-permanent hair color
- CPermanent hair color
- DTemporary hair color
Show answer & explanationAnswer & explanation
Correct answer: B. Demi-permanent hair color
Demi-permanent hair colors are ideal for depositing color, enhancing natural tones, and blending gray without lifting the natural pigment. They fade gradually, typically lasting 4-6 weeks.
Why the other options are wrong
- A. Bleach removes natural pigment and does not deposit color.
- C. Permanent hair color lightens and deposits, providing a lasting change.
- D. Temporary hair color only coats the hair surface and washes out in one shampoo.
Demi-Permanent Hair Color
A hair color product that deposits color without lightening the natural hair pigment. It lasts longer than temporary color but fades gradually over several shampoos.
- Uses an alkaline agent (usually ethanolamine or ammonia derivative) with a low volume developer (peroxide).
- Penetrates the cuticle and partially into the cortex.
- Does not contain enough ammonia to lift natural pigment.
- Ideal for blending gray, enhancing natural color, or refreshing faded permanent color.
Memory trick: Demi-permanent: 'The 'medium' color, not too temporary, not too permanent, just right for a fade.'
