NIC Barber Written (Theory) ExamHair Care ServicesHard
A barber is performing a consultation for a client who desires to lighten their natural black hair to a medium brown shade. The client has no previous color in their hair. Which type of hair color product is most suitable for achieving this result in a single application?
- ASemi-permanent hair color
- BTemporary hair color
- CPermanent hair color
- DDemi-permanent hair color
Show answer & explanationAnswer & explanation
Correct answer: C. Permanent hair color
To lighten natural hair, an oxidizing agent (developer) is required, which is only found in permanent hair color formulations. Temporary, demi-permanent, and semi-permanent colors can only deposit color, not lighten the natural pigment.
Why the other options are wrong
- A. Semi-permanent hair color deposits color but does not lighten natural hair.
- B. Temporary hair color only deposits pigment on the surface and does not lighten.
- D. Demi-permanent hair color deposits color but does not lighten natural hair.
Permanent Hair Color (Lightening)
Hair color products that use an alkaline ingredient (like ammonia) and an oxidizing agent (developer) to simultaneously lighten the hair's natural pigment and deposit new color, creating a permanent change.
- Lightens natural pigment
- Deposits new color
- Contains ammonia and developer
- Permanent results
Memory trick: To 'permanently' 'lighten' a dark room, you need a strong 'light' (permanent color).
