Correct answer

Helpful before shampooing to loosen debris, but the scalp should not be irritated/scratched before a chemical service

A Never done
B Helpful before shampooing to loosen debris, but the scalp should not be irritated/scratched before a chemical service
C Required immediately before a chemical service
D Only for color

Why this is the answer

Brushing before a regular shampoo helps loosen debris and distribute natural oils, but before a chemical service the cosmetologist should avoid vigorous brushing or scratching that could irritate or abrade the scalp, since broken or irritated skin can react badly to chemicals. In general, the scalp should be intact and undisturbed before applying strong chemicals. Knowing when brushing helps and when it should be limited — especially protecting the scalp before chemical work — reflects the careful, safety-minded approach the exam rewards.
