Cross-check both sides of a finished cut for balance by using the nose, ears, and jaw as reference points.

Explain when to use shears, clippers, trimmers, razors, and thinning shears for texture and weight removal, and state the safety rule for each.

Describe the chemistry of an oxidative color versus a temporary or semi-permanent color, and state which one requires a developer.

Explain the safe handling, storage, and disposal of peroxide, bleach, and color products, and the safety rule for metal tools near chemicals.

Explain how a relaxer alters the hair's disulfide bonds and why a neutralizing shampoo is mandatory afterward.

Compare the two relaxer strengths and the two application methods, and state the risk factors that make a client unsuitable for a relaxer.

List the implements and tools in a barber kit, state the purpose and maintenance of each, and identify which require disinfection between clients.

Draft a shop policy covering client records, consent for chemical services, pricing, and late or no-show handling.
