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?

  1. APermanent hair color
  2. BTemporary hair color
  3. CDemi-permanent hair color
  4. DSemi-permanent hair color
Show answer & 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.
