NIC Barber Written (Theory) ExamHair Care ServicesMedium
A barber is performing a chemical hair coloring service on a client who desires a significant lift in their natural hair color, from a dark brown (level 3) to a light blonde (level 9). To achieve this result, which type of hair color product would be most appropriate?
- ASemi-permanent color
- BDemi-permanent color
- CPermanent color
- DTemporary color
Show answer & explanationAnswer & explanation
Correct answer: C. Permanent color
Permanent hair color is the only type of hair color that can lighten natural hair color, as it contains ammonia and requires a developer (hydrogen peroxide) to open the cuticle and penetrate the cortex, allowing for both lift and deposit.
Why the other options are wrong
- A. Semi-permanent colors deposit color on the hair surface and cuticle, but cannot lighten the natural hair color.
- B. Demi-permanent colors deposit color but cannot lighten the natural hair color.
- D. Temporary colors only coat the hair surface and do not lighten or permanently alter the hair.
Permanent Hair Color
A hair coloring product that is mixed with a developer (hydrogen peroxide) to simultaneously lighten the natural hair pigment and deposit new artificial pigment into the hair cortex, resulting in a lasting color change.
- Lifts and deposits color
- Requires developer (peroxide)
- Long-lasting results
- Covers gray hair effectively
Memory trick: Permanent color lifts and lasts, unlike temporary tints.
