Barber theory full analysis: what the $39 report shows

A real question from the full analysis

This is how each question you miss appears in the report. The question, the right answer, the explanation and the source are real. The answer shown as yours is an example, not anyone's data.

Before a first-time permanent color service, a barber performs a predisposition test. Where do NIC's barber practical examination criteria have candidates demonstrate this test?

• A Behind the ear
• B On the scalp at the crown
• C On a strand of hair at the nape
• D On the palm of the hand

Example answer, marked sure: B · Correct answer: A

A is correct. NIC's Barber Styling practical bulletin directs candidates to demonstrate the predisposition test behind the ear and the strand test on any area of the head, as two separate steps. The predisposition test checks the skin for a reaction to the product, so it is done on skin rather than on hair. FDA explains that coal-tar hair dye labels must carry a caution calling for a preliminary test, and it advises a patch test every time before dyeing. B is wrong because NIC places the test behind the ear, not in the area to be colored. C is wrong because a test on a strand of hair is the strand test. D is wrong because NIC names the area behind the ear. Rule: predisposition test on skin, strand test on hair.
