Sample Practice Question & Solution
Question 1: When performing a permanent wave service on coarse, resistant hair with low porosity, which perm solution formula is recommended?
A) True acid wave (pH 4.5–7.0) requiring an external heat source
B) Ammonium thioglycolate (alkaline wave, pH 9.0–9.6)
C) Exothermic acid wave with low pH
D) Neutralizing solution only
Correct Answer: B) Ammonium thioglycolate (alkaline wave, pH 9.0–9.6)
Explanation: Alkaline waves (cold waves) formulated with ammonium thioglycolate process at room temperature and quickly swell the cuticle of coarse, low-porosity resistant hair without requiring heat.
