Which guideline relates to the complete hair design service?

• A. Recommend products to maintain the appearance and condition of your client's hair.
• B. Check scalp for any diseases or disorders.
• C. Postpone treatment of burn until after the service.
• D. Ensure equipment is clean and disinfected.

Answer: (A)

Aftercare guidance is part of delivering a complete hair design service. Recommending products to maintain the appearance and condition of your client’s hair directly supports the finished look, helps keep the style, and preserves hair health between visits, which is why this option best fits the concept of a complete service. The other guidelines focus on safety checks, injury management, or sanitation—essential practices—but they do not directly pertain to concluding the service with guidance on maintaining the result.
