A cosmetologist is preparing to perform a hair coloring service on a client who has 50% gray hair and wants a permanent color that will provide 100% gray coverage and a lasting result. Which type of hair color would be most appropriate for this client's needs?
- ASemi-permanent hair color
- BTemporary hair color
- CPermanent hair color
- DDemi-permanent hair color
Show answer & explanationAnswer & explanation
Correct answer: C. Permanent hair color
Permanent hair color is the only type that can provide 100% gray coverage and a lasting color change because it penetrates into the cortex and chemically alters the hair's natural pigment.
Why the other options are wrong
- A. Semi-permanent hair color deposits color but does not lift, and typically provides blending for gray hair, not 100% coverage, and washes out over time.
- B. Temporary hair color only coats the hair surface and washes out easily, offering no gray coverage.
- D. Demi-permanent hair color also deposits color without lifting and offers better gray blending than semi-permanent, but generally not 100% opaque coverage, and fades over time.
Permanent Hair Color
A type of hair color that lightens the natural pigment and deposits artificial pigment simultaneously, providing 100% gray coverage and a long-lasting color change that grows out rather than washing out.
- Requires developer (hydrogen peroxide)
- Penetrates cortex
- Provides 100% gray coverage
- Permanent change, grows out
Memory trick: Permanent color is for 'forever' gray coverage.
