Which guideline is performed prior to the hair design service?

• A. Check scalp for any diseases or disorders.
• B. Check nails for health.
• C. Check makeup suitability.
• D. Check client history.

Answer: (A)

A scalp health check is performed before the hair design service to protect the client and guide the treatment. By screening the scalp for diseases or disorders, the stylist can spot infections, inflammation, or conditions that could be contagious or aggravated by products and styling techniques. This allows the service to proceed safely, be adjusted if needed, or be postponed with a professional referral if necessary. While other checks like nails, makeup suitability, or past history might appear in broader intake, they don’t directly address the immediate safety and suitability of the hair service the way assessing scalp condition does.
