NIC Barber Written (Theory) ExamHair Care ServicesMedium
A barber is preparing to perform a hair coloring service. The client has 50% gray hair and wants full gray coverage with a natural-looking result. Which type of hair color product is specifically designed to provide 100% gray coverage?
- ASemi-permanent color
- BTemporary color
- CPermanent color
- DDemi-permanent color
Show answer & explanationAnswer & explanation
Correct answer: C. Permanent color
Permanent hair color is the only type of hair color that provides 100% gray coverage. It works by opening the cuticle to deposit color molecules into the cortex, effectively replacing the missing pigment in gray hair.
Why the other options are wrong
- A. Semi-permanent colors stain the cuticle and offer minimal to no gray blending, not coverage.
- B. Temporary colors do not penetrate the hair and offer no gray coverage.
- D. Demi-permanent colors can blend gray effectively (up to 50-75% depending on formulation) but typically do not provide 100% opaque coverage.
Gray Hair Coverage
The ability of a hair color product to effectively conceal or blend gray (unpigmented) hair, with permanent color being the only option for 100% opaque coverage.
- Gray hair lacks natural pigment.
- Permanent color penetrates the cortex for full coverage.
- Demi-permanent color can blend gray but not fully cover if 100% is desired.
Memory trick: Permanent Color is the 'P' for 'Perfect' Gray Coverage.
