A client with 70% gray hair desires a permanent hair color that will provide full gray coverage and a vibrant, long-lasting result. Which type of hair color product is best suited for this purpose?
- APermanent hair color
- BTemporary hair color
- CDemi-permanent hair color
- DSemi-permanent hair color
Show answer & explanationAnswer & explanation
Correct answer: A. Permanent hair color
Permanent hair color is formulated to provide the most effective gray coverage and long-lasting results because it penetrates the hair shaft and chemically alters the hair's natural pigment.
Why the other options are wrong
- B. Temporary hair color only coats the hair surface and offers no gray coverage.
- C. Demi-permanent hair color provides blending for gray hair but generally not full coverage, and it fades over time.
- D. Semi-permanent hair color stains the cuticle and offers minimal to no gray coverage, washing out over several shampoos.
Permanent Hair Color
Hair color product that mixes with a developer to penetrate the hair shaft, permanently altering natural pigment and providing lasting color and gray coverage.
- Uses oxidative dyes and an alkaline agent (ammonia) with hydrogen peroxide developer
- Lifts natural pigment and deposits new color simultaneously
- Provides 100% gray coverage
- Creates a permanent change, requires touch-ups for new growth
Memory trick: For 'Full Gray' coverage, 'Permanent' color is the only way.
