Texas Class A Barber Written ExamChemical ServicesHard
A barber is applying a tint back (darker) hair color to a client whose hair was previously lightened to a very pale yellow. To ensure the new color holds evenly and appears natural, what pre-treatment step is essential?
- AApplying a strong porosity equalizer
- BApplying a protein filler
- CApplying a deep conditioning treatment
- DApplying a clarifying shampoo
Show answer & explanationAnswer & explanation
Correct answer: B. Applying a protein filler
When coloring hair darker after it has been lightened to a very pale yellow, the hair often lacks the underlying pigment (red, orange, yellow) needed for the new color to appear natural. A protein filler helps to replace these missing pigments and equalize porosity, ensuring even color absorption and a true-to-tone result.
Why the other options are wrong
- A. While porosity equalization is important, a 'strong porosity equalizer' alone might not provide the necessary missing 'fillers' (underlying pigments) needed for a tint back to look natural.
- C. A deep conditioning treatment would improve hair condition but not provide the necessary underlying pigment or porosity equalization for a successful tint back.
- D. A clarifying shampoo would remove product buildup but wouldn't address the missing underlying pigments or extreme porosity.
Tint Back Pre-Treatment
Before coloring lightened hair darker (tint back), apply a protein filler to replace missing underlying pigments and equalize porosity for even, natural-looking results.
- Addresses missing red/orange/yellow pigments
- Prevents dull, muddy, or greenish tones
- Equalizes porosity for even absorption
Memory trick: Tint back needs 'Protein' to 'Pre-pigment' for perfection.
