Texas Class A Barber Written ExamChemical ServicesMedium
A barber is performing a consultation for a client who has previously undergone multiple chemical services, including coloring and perming. The hair feels rough, brittle, and breaks easily. Which product ingredient would be most beneficial for this client's hair to help restore strength and integrity?
- ASurfactants
- BHumectants
- CProteins
- DSilicones
Show answer & explanationAnswer & explanation
Correct answer: C. Proteins
Proteins help to reinforce the hair's structure, fill in gaps in the cuticle, and strengthen chemically damaged or brittle hair, improving its elasticity and reducing breakage.
Why the other options are wrong
- A. Surfactants are cleansing agents found in shampoos and would not be used to restore strength to damaged hair.
- B. Humectants draw moisture into the hair, which is beneficial for hydration, but not directly for strengthening brittle, broken hair.
- D. Silicones provide shine and slip, creating a smooth feel, but do not repair the internal structure of the hair.
Protein-Based Hair Products
Hair products containing protein (e.g., keratin, wheat protein, silk protein) that help to strengthen, repair, and rebuild the hair's structure, especially after chemical damage.
- Strengthens hair bonds
- Improves elasticity and reduces breakage
- Fills in cuticle gaps
- Beneficial for chemically treated, damaged, or brittle hair
Memory trick: PROTEIN for PROTECTION and structural repair.
