Texas Class A Barber Written ExamChemical ServicesHard
A barber is coloring a client's hair from a natural level 6 (light brown) to a level 3 (dark brown). The hair is highly porous from previous chemical services. What specific product knowledge is critical for the barber to consider to prevent an uneven, dull, or muddy color result?
- APre-softening the hair with an alkaline solution before coloring
- BUsing a higher volume developer to ensure deep penetration
- CIncreasing the processing time to allow the color to fully absorb
- DApplying a filler or pre-pigmentation product before the color application
Show answer & explanationAnswer & explanation
Correct answer: D. Applying a filler or pre-pigmentation product before the color application
When coloring porous hair darker, especially when going several levels darker, a filler or pre-pigmentation product is essential. This product replaces missing underlying warm tones, ensuring even color absorption and preventing flat, dull, or muddy results on over-porous areas.
Why the other options are wrong
- A. Pre-softening with an alkaline solution would open the cuticle further, making porous hair even more susceptible to uneven color and damage.
- B. A higher volume developer would lighten the hair, which is not the goal when going darker, and can further damage porous hair.
- C. Increasing processing time on porous hair can lead to over-deposit in some areas and an overly dark or dull result, rather than evenness.
Pre-Pigmentation / Fillers
Products used before a color service, especially when going darker on porous or lightened hair, to replace missing underlying pigment and equalize porosity for even color absorption.
- Used to restore missing warmth (red/orange/yellow)
- Equalizes porosity for even color deposit
- Prevents dull, muddy, or greenish results
- Applied before the final color application
