spiral curling specifically employs heat to manipulate the hair's texture into curls.

Correct Option: C) To check for allergic reactions.
Rationale: Performing a patch test is critical before applying hair color products to
identify any allergic reactions the client may have to the colorants. This is a safety
measure that can prevent severe skin reactions, ensuring the well-being of the client
before the chemical treatment is applied.

dissatisfaction.

• A) 2.5 to 3.5
• B) 4.5 to 5.5
• C) 6.0 to 7.0
• D) 8.0 to 9.0
Correct Option: B) 4.5 to 5.5.
Rationale: The pH of hair and scalp typically falls within the range of 4.5 to 5.5, which is

cuticle layer closed and intact, preventing damage and dryness.
9. Hair is primarily made of which protein?
