  1. The outermost protective layer of the hair shaft composed of overlapping scales is the:

    Answer: Cuticle

    The cuticle is the outermost layer of the hair shaft; its overlapping scale structure protects the inner cortex and medulla.

  2. Chemical hair relaxers permanently straighten hair by:

    Answer: Breaking and reforming disulfide bonds within the cortex

    Relaxers use chemicals to permanently break the disulfide bonds in the cortex, altering the curl pattern until new hair grows in.

  3. What is the approximate pH range of a lye (sodium hydroxide) hair relaxer?

    Answer: 12.0–14.0

    Sodium hydroxide relaxers have a very high pH of 12–14, making them highly alkaline in order to penetrate and restructure the hair shaft.

  4. A client allergy patch test for hair color should be performed:

    Answer: 24 to 48 hours before the scheduled color service

    A 24–48 hour window gives enough time for any allergic sensitivity reaction to develop and become visible before the full application.

  5. During a permanent wave (perm) service, the neutralizer is applied in order to:

    Answer: Stop the waving action and re-form disulfide bonds in the new shape

    The neutralizer oxidizes the broken disulfide bonds, locking the hair into its new curled shape around the perm rods permanently.

  6. 20-volume hydrogen peroxide developer contains what percentage of hydrogen peroxide?

    Answer: 6%

    20-volume developer contains 6% hydrogen peroxide; each 10-volume increment equals approximately 3% H₂O₂ concentration.

  7. Before performing any chemical service, a barber should always begin by:

    Answer: Performing a thorough scalp analysis to identify abrasions, sensitivity, or contraindications

    A scalp analysis identifies cuts, sores, sensitivity, or other conditions that would make a chemical service unsafe before any product is applied.
