California Barber Written ExamHair Care ServicesEasy
A barber is preparing to perform a hair coloring service on a client who has 50% gray hair and desires a natural-looking, permanent color that will cover the gray effectively. Which type of hair color formulation is best suited for this purpose?
- APermanent color
- BTemporary color
- CDemi-permanent color
- DSemi-permanent color
Show answer & explanationAnswer & explanation
Correct answer: A. Permanent color
Permanent hair color is the only type that can effectively cover 100% of gray hair and provide a lasting color change, as it penetrates the hair shaft and chemically alters the hair's natural pigment.
Why the other options are wrong
- B. Temporary color only coats the hair surface and washes out with one shampoo, offering no gray coverage.
- C. Demi-permanent color blends gray hair but does not provide 100% coverage, and it fades over 20-28 shampoos.
- D. Semi-permanent color stains the cuticle and only lasts 4-6 shampoos, providing minimal to no gray blending, not coverage.
Permanent Hair Color
Hair color formulation that uses an oxidative dye and ammonia/alkalizing agent to penetrate the hair shaft, lift natural pigment, and deposit new color for lasting gray coverage.
- Provides 100% gray coverage.
- Chemically alters hair pigment.
- Requires developer for activation.
Memory trick: PERMANENT color is PERMANENTLY good at covering gray.
